[IA64] Move include/asm-ia64 to arch/ia64/include/asm

After moving the the include files there were a few clean-ups:

1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>

2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.

3) Some header files mentioned their own names in initial comments. Just
deleted these self references.

+ * Each BOARD consists of COMPONENTs and the BOARD structure has 
+ * pointers (offsets) to its COMPONENT structure.
+ * The COMPONENT structure has version info, size and speed info, revision,
+ * error info and the NIC info. This structure can accommodate any
+ * BOARD with arbitrary COMPONENT composition.
+ *
+ * The ERRORINFO part of each BOARD has error information
+ * that describes errors about the BOARD itself. It also has flags to
+ * indicate the COMPONENT(s) on the board that have errors. The error 
+ * information specific to the COMPONENT is present in the respective 
+ * COMPONENT structure.
+ *
+ * The ERRORINFO structure is also treated like a COMPONENT, ie. the 
+ * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
+ * structure also has a pointer to the ERRORINFO structure. This is 
+ * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
+ * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where 
+ * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
+ * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info 
+ * which is present on the REMOTE NODE.(TBD)
+ * REMOTE ERRINFO can be stored on any of the nearest nodes 
+ * or on all the nearest nodes.(TBD)
+ * Like BOARD structures, REMOTE ERRINFO structures can be built locally
+ * using the rboard errinfo pointer.
+ *
+ * In order to get useful information from this Data organization, a set of
+ * interface routines are provided (TBD). The important thing to remember while
+ * manipulating the structures, is that, the NODE number information should
+ * be used. If the NODE is non-zero (remote) then each offset should
+ * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR. 
+ * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
+ * 
+ * Note that these structures do not provide much info about connectivity.
+ * That info will be part of HWGRAPH, which is an extension of the cfg_t
+ * data structure. (ref IP27prom/cfg.h) It has to be extended to include
+ * the IO part of the Network(TBD).
+ *
+ * The data structures below define the above concepts.

+ * PIC AS DEVICE ZERO
+ * ------------------
+ *
+ * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
+ * be designated as 'device 0'.   That is a departure from earlier SGI
+ * PCI bridges.  Because of that we use config space 1 to access the
+ * config space of the first actual PCI device on the bus.
+ * Here's what the PIC manual says:
+ *
+ *     The current PCI-X bus specification now defines that the parent
+ *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
+ *     reduced the total number of devices from 8 to 4 and removed the
+ *     device registers and windows, now only supporting devices 0,1,2, and
+ *     3. PIC did leave all 8 configuration space windows. The reason was
+ *     there was nothing to gain by removing them. Here in lies the problem.
+ *     The device numbering we do using 0 through 3 is unrelated to the device
+ *     numbering which PCI-X requires in configuration space. In the past we
+ *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
+ *     PCI-X requires we start a 1, not 0 and currently the PX brick
+ *     does associate our:
+ *
+ *         device 0 with configuration space window 1,
+ *         device 1 with configuration space window 2,
+ *         device 2 with configuration space window 3,
+ *         device 3 with configuration space window 4.
+ *
+ * The net effect is that all config space access are off-by-one with
+ * relation to other per-slot accesses on the PIC.
+ * Here is a table that shows some of that:
+ *
+ *                               Internal Slot#
+ *           |

+ * Description:  This register's value is a bit vector that guards      *
+ * access to local registers within the II as well as to external       *
+ * Crosstalk widgets. Each bit in the register corresponds to a         *
+ * particular region in the system; a region consists of one, two or    *
+ * four nodes (depending on the value of the REGION_SIZE field in the   *
+ * LB_REV_ID register, which is documented in Section 8.3.1.1). The     *
+ * protection provided by this register applies to PIO read             *
+ * operations as well as PIO write operations. The II will perform a    *
+ * PIO read or write request only if the bit for the requestor's        *
+ * region is set; otherwise, the II will not perform the requested      *
+ * operation and will return an error response. When a PIO read or      *
+ * write request targets an external Crosstalk widget, then not only    *
+ * must the bit for the requestor's region be set in the ILAPR, but     *
+ * also the target widget's bit in the IOWA register must be set in     *
+ * order for the II to perform the requested operation; otherwise,      *
+ * the II will return an error response. Hence, the protection          *
+ * provided by the IOWA register supplements the protection provided    *
+ * by the ILAPR for requests that target external Crosstalk widgets.    *
+ * This register itself can be accessed only by the nodes whose         *
+ * region ID bits are enabled in this same register. It can also be     *
+ * accessed through the IAlias space by the local processors.           *

+ * Prescalar field, all IPRTE registers with their valid bits set       *

+ * (illustrated in the table above). Each row contains the 4            *
+ * registers required for a single CRB Entry. The first doubleword      *
+ * (column) for each entry is labeled A, and the second doubleword      *
+ * (higher address) is labeled B, the third doubleword is labeled C,    *
+ * the fourth doubleword is labeled D and the fifth doubleword is       *
+ * labeled E. All CRB entries have their addresses on a quarter         *
+ * cacheline aligned boundary.                   *
+ * Upon reset, only the following fields are initialized: valid         *
+ * (VLD), priority count, timeout, timeout valid, and context valid.    *
+ * All other bits should be cleared by software before use (after       *
+ * recovering any potential error state from before the reset).         *

+ * While the transfer is in progress, hardware will decrement the       *
+ * length field with each successful block that is copied. Once the     *
+ * transfer completes, hardware will clear the Busy bit. The length     *
+ * field will also contain the number of cache lines left to be         *
+ * transferred.                                                         *

+ *  Definitions of terms (these definitions are for IA64 ONLY. Other architectures
+ *  use cpuid/cpunum quite defferently):
+ *
+ *         CPUID - a number in range of 0..NR_CPUS-1 that uniquely identifies
+ *              the cpu. The value cpuid has no significance on IA64 other than
+ *              the boot cpu is 0.
+ *                      smp_processor_id() returns the cpuid of the current cpu.
+ *
+ *         CPU_PHYSICAL_ID (also known as HARD_PROCESSOR_ID)
+ *              This is the same as 31:24 of the processor LID register
+ *                      hard_smp_processor_id()- cpu_physical_id of current processor
+ *                      cpu_physical_id(cpuid) - convert a <cpuid> to a <physical_cpuid>
+ *                      cpu_logical_id(phy_id) - convert a <physical_cpuid> to a <cpuid> 
+ *                              * not real efficient - don't use in perf critical code
+ *
+ *         SLICE - a number in the range of 0 - 3 (typically) that represents the
+ *              cpu number on a brick.
+ *
+ *         SUBNODE - (almost obsolete) the number of the FSB that a cpu is
+ *              connected to. This is also the same as the PI number. Usually 0 or 1.
+ *
+ *      NOTE!!!: the value of the bits in the cpu physical id (SAPICid or LID) of a cpu has no 
+ *      significance. The SAPIC id (LID) is a 16-bit cookie that has meaning only to the PROM.
+ *
+ *

+/*
+ * DMA space
+ *
+ * The CA aperature (ie. bus address range) mapped by the GART is segmented into
+ * two parts.  The lower portion of the aperature is used for mapping 32 bit
+ * PCI addresses which are managed by the dma interfaces in this file.  The
+ * upper poprtion of the aperature is used for mapping 48 bit AGP addresses.
+ * The AGP portion of the aperature is managed by the agpgart_be.c driver
+ * in drivers/linux/agp.  There are ca-specific hooks in that driver to
+ * manipulate the gart, but management of the AGP portion of the aperature
+ * is the responsibility of that driver.
+ *
+ * CA allows three main types of DMA mapping:
+ *
+ * PCI 64-bit   Managed by this driver
+ * PCI 32-bit   Managed by this driver
+ * AGP 48-bit   Managed by hooks in the /dev/agpgart driver
+ *
+ * All of the above can optionally be remapped through the GART.  The following
+ * table lists the combinations of addressing types and GART remapping that
+ * is currently supported by the driver (h/w supports all, s/w limits this):
+ *
+ *              PCI64           PCI32           AGP48
+ * GART         no              yes             yes
+ * Direct       yes             yes             no
+ *
+ * GART remapping of PCI64 is not done because there is no need to.  The
+ * 64 bit PCI address holds all of the information necessary to target any
+ * memory in the system.
+ *
+ * AGP48 is always mapped through the GART.  Management of the AGP48 portion
+ * of the aperature is the responsibility of code in the agpgart_be driver.
+ *
+ * The non-64 bit bus address space will currently be partitioned like this:
+ *
+ *      0xffff_ffff_ffff        +--------
+ *                              | AGP48 direct
+ *                              | Space managed by this driver
+ *      CA_AGP_DIRECT_BASE      +--------
+ *                              | AGP GART mapped (gfx aperature)
+ *                              | Space managed by /dev/agpgart driver
+ *                              | This range is exposed to the agpgart
+ *                              | driver as the "graphics aperature"
+ *      CA_AGP_MAPPED_BASE      +-----
+ *                              | PCI GART mapped
+ *                              | Space managed by this driver          
+ *      CA_PCI32_MAPPED_BASE    +----
+ *                              | PCI32 direct
+ *                              | Space managed by this driver
+ *      0xC000_0000             +--------
+ *      (CA_PCI32_DIRECT_BASE)
+ *
+ * The bus address range CA_PCI32_MAPPED_BASE through CA_AGP_DIRECT_BASE
+ * is what we call the CA aperature.  Addresses falling in this range will
+ * be remapped using the GART.
+ *
+ * The bus address range CA_AGP_MAPPED_BASE through CA_AGP_DIRECT_BASE
+ * is what we call the graphics aperature.  This is a subset of the CA
+ * aperature and is under the control of the agpgart_be driver.
+ *
+ * CA_PCI32_MAPPED_BASE, CA_AGP_MAPPED_BASE, and CA_AGP_DIRECT_BASE are
+ * somewhat arbitrary values.  The known constraints on choosing these is:
+ *
+ * 1)  CA_AGP_DIRECT_BASE-CA_PCI32_MAPPED_BASE+1 (the CA aperature size)
+ *     must be one of the values supported by the ca_gart_aperature register.
+ *     Currently valid values are: 4MB through 4096MB in powers of 2 increments
+ *
+ * 2)  CA_AGP_DIRECT_BASE-CA_AGP_MAPPED_BASE+1 (the gfx aperature size)
+ *     must be in MB units since that's what the agpgart driver assumes.
+ */
+
+/*
+ * Define Bus DMA ranges.  These are configurable (see constraints above)
+ * and will probably need tuning based on experience.
+ */
+
+
+/*
+ * 11/24/03
+ * CA has an addressing glitch w.r.t. PCI direct 32 bit DMA that makes it
+ * generally unusable.  The problem is that for PCI direct 32 
+ * DMA's, all 32 bits of the bus address are used to form the lower 32 bits
+ * of the coretalk address, and coretalk bits 38:32 come from a register.
+ * Since only PCI bus addresses 0xC0000000-0xFFFFFFFF (1GB) are available
+ * for DMA (the rest is allocated to PIO), host node addresses need to be
+ * such that their lower 32 bits fall in the 0xC0000000-0xffffffff range
+ * as well.  So there can be no PCI32 direct DMA below 3GB!!  For this
+ * reason we set the CA_PCI32_DIRECT_SIZE to 0 which essentially makes
+ * tioca_dma_direct32() a noop but preserves the code flow should this issue
+ * be fixed in a respin.
+ *
+ * For now, all PCI32 DMA's must be mapped through the GART.

+ * Note that the ordering of these steps is crucial to avoid races on MP machines.

+ * This file defines various macros to transfer memory areas across
+ * the user/kernel boundary.  This needs to be done carefully because
+ * this code is executed in kernel mode and uses user-specified
+ * addresses.  Thus, we need to be careful not to let the user to
+ * trick us into accessing kernel memory that would normally be
+ * inaccessible.  This code is also fairly performance sensitive,
+ * so we want to spend as little time doing safety checks as
+ * possible.
+ *
+ * To make matters a bit more interesting, these macros sometimes also
+ * called from within the kernel itself, in which case the address
+ * validity check must be skipped.  The get_fs() macro tells us what
+ * to do: if get_fs()==USER_DS, checking is performed, if
+ * get_fs()==KERNEL_DS, checking is bypassed.
+ *
+ * Note that even if the memory area specified by the user is in a
+ * valid address range, it is still possible that we'll get a page
+ * fault while accessing it.  This is handled by filling out an
+ * exception handler fixup entry for each instruction that has the
+ * potential to fault.  When such a fault occurs, the page fault
+ * handler checks to see whether the faulting instruction has a fixup
+ * associated and, if so, sets r8 to -EFAULT and clears r9 to 0 and
+ * then resumes execution at the continuation point.

+ * Core file format: The core file is written in such a way that gdb

+ * follows:
+ *
+ *  upage: 1 page consisting of a user struct that tells gdb
+ *      what is present in the file.  Directly after this is a
+ *      copy of the task_struct, which is currently not used by gdb,
+ *      but it may come in handy at some point.  All of the registers
+ *      are stored as part of the upage.  The upage should always be
+ *      only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *      current->brk to pick up all of the user variables, plus any memory
+ *      that may have been sbrk'ed.  No attempt is made to determine if a
+ *      page is demand-zero or if a page is totally unused, we just cover
+ *      the entire range.  All of the addresses are rounded in such a way
+ *      that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *      backtrace.  We need to write the data from usp to
+ *      current->start_stack, so we round each of these in order to be able
+ *      to write an integer number of pages.

+ *
+ *      N       - Number of bits in the node portion of a socket physical
+ *                address.
+ *
+ *      NASID   - network ID of a router, Mbrick or Cbrick. Nasid values of
+ *                routers always have low bit of 1, C/MBricks have low bit
+ *                equal to 0. Most addressing macros that target UV hub chips
+ *                right shift the NASID by 1 to exclude the always-zero bit.
+ *                NASIDs contain up to 15 bits.
+ *
+ *      GNODE   - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
+ *                of nasids.
+ *
+ *      PNODE   - the low N bits of the GNODE. The PNODE is the most useful variant
+ *                of the nasid for socket usage.
