+
+           The added complication is that we don't know that the 5V slots are

+           plugged into a 3.3V slot, and this changes the bus numbering.

+           never been used in practice.
+

-          VESA. If you have PCI, say Y, otherwise N.
-
-          The PCI-HOWTO, available from
-          <http://www.tldp.org/docs.html#howto>, contains valuable

-          Enable this option if your platform does not have a CPU cache which
-          remains coherent with PCI DMA. It is safest to say 'Y', although you
-          will see better performance if you can say 'N', because the PCI DMA
-          code will not have to flush the CPU's caches. If you have a PCI host
-          bridge integrated with your SH CPU, refer carefully to the chip specs
-          to see if you can say 'N' here. Otherwise, leave it as 'Y'.

-           at the point where we cross from 5V to 3.3V is not the normal case.
-
-           The added complication is that we don't know that the 5V slots are
-           always bus 2, because a card containing a PCI-PCI bridge may be
-           plugged into a 3.3V slot, and this changes the bus numbering.
-
-           Also, the Cayman has an intermediate PCI bus that goes a custom
-           expansion board header (and to the secondary bridge).  This bus has
-           never been used in practice.

- *
- * When __up() is called, the count was negative before
- * incrementing it, and we need to wake up somebody.

- * This routine adds one to the count of processes that need to
- * wake up and exit.  ALL waiting processes actually wake up but
- * only the one that gets to the "waking" field first will gate
- * through and acquire the semaphore.  The others will go back
- * to sleep.
- *
- * Note that these functions are only called when there is
- * contention on the lock, and as such all this is the
- * "non-critical" part of the whole semaphore business. The
- * critical part is the inline stuff in <asm/semaphore.h>

+          A standard SEGA Dreamcast comes with a modified CD ROM drive called a
+          "GD-ROM" by SEGA to signify it is capable of reading special disks
+          with up to 1 GB of data. This drive will also read standard CD ROM
+          disks. Select this option to access any disks in your GD ROM drive.
+          Most users will want to say "Y" here.
+          You can also build this as a module which will be called gdrom.ko

- * reserved bits, with the real logic existing in data array 2.
- *
- * The downside to this is that we can no longer fit everything in to a 32-bit

- * side, this gives us quite a few spare bits to play with for future usage.

+ * Linux PTEL encoding.
+ *
+ * Hardware and software bit definitions for the PTEL value (see below for
+ * notes on SH-X2 MMUs and 64-bit PTEs):
+ *
+ * - Bits 0 and 7 are reserved on SH-3 (_PAGE_WT and _PAGE_SZ1 on SH-4).
+ *
+ * - Bit 1 is the SH-bit, but is unused on SH-3 due to an MMU bug (the
+ *   hardware PTEL value can't have the SH-bit set when MMUCR.IX is set,
+ *   which is the default in cpu-sh3/mmu_context.h:MMU_CONTROL_INIT).
+ *
+ *   In order to keep this relatively clean, do not use these for defining
+ *   SH-3 specific flags until all of the other unused bits have been
+ *   exhausted.
+ *
+ * - Bit 9 is reserved by everyone and used by _PAGE_PROTNONE.
+ *
+ * - Bits 10 and 11 are low bits of the PPN that are reserved on >= 4K pages.
+ *   Bit 10 is used for _PAGE_ACCESSED, bit 11 remains unused.
+ *
+ * - On 29 bit platforms, bits 31 to 29 are used for the space attributes
+ *   and timing control which (together with bit 0) are moved into the
+ *   old-style PTEA on the parts that support it.
+ *
+ * XXX: Leave the _PAGE_FILE and _PAGE_WT overhaul for a rainy day.
+ *
+ * SH-X2 MMUs and extended PTEs
+ *
+ * SH-X2 supports an extended mode TLB with split data arrays due to the
+ * number of bits needed for PR and SZ (now EPR and ESZ) encodings. The PR and
+ * SZ bit placeholders still exist in data array 1, but are implemented as
+ * reserved bits, with the real logic existing in data array 2.
+ *
+ * The downside to this is that we can no longer fit everything in to a 32-bit
+ * PTE encoding, so a 64-bit pte_t is necessary for these parts. On the plus
+ * side, this gives us quite a few spare bits to play with for future usage.

- * Core file format: The core file is written in such a way that gdb
- * can understand it and provide useful information to the user (under
- * linux we use the `trad-core' bfd).  The file contents are as 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.
