* [ARM] 4184/1: iop: cp6 access handler (undef_hook)Dan Williams2007-02-14
| | | | | | | | | | | | | | | Enable svc access to cp6 via an undefined instruction hook. Do not enable access for usr code. This patch also makes iop13xx select PLAT_IOP, this requires a small change to drivers/i2c/busses/i2c-iop3xx.c. Per Lennert Buytenhek's note, the cp6 trap routine is moved to arch/arm/plat-iop Per Nicolas Pitre's note, the cp_wait is skipped since the latency to return to the faulting function is longer than cp_wait.

* [ARM] 4183/1: do_undefinstr: read svc undefined instructions with svc privilegesDan Williams2007-02-14
| | | | | | | | | | | | do_undefinstr currently does not expect undefined instructions in kernel code, since it always uses get_user() to read the instruction. Dereference the 'pc' pointer directly in the SVC case. Per Nicolas Pitre's note, kernel code is never in thumb mode.

* [ARM] 4182/1: iop3xx: fix the ioremap implementation to not remap static rangesDan Williams2007-02-14
| | | | | | | | | | Implement a custom ioremap implementation for iop3xx. This saves establishing new mappings. It also cleans up the PCI IO resource to be a physical address rather than a virtual address as Russell pointed out on the original iop13xx port.

* [ARM] Move processor_modes[] to .../process.cRussell King2007-02-06
| | | | | | | | | | | | | | bad_mode() currently prints the mode which caused the exception, and then causes an oops dump to be printed which again displays this information (since the CPSR in the struct pt_regs is correct.) This leads to processor_modes[] being shared between traps.c and process.c with a local declaration of it. We can clean this up by moving processor_modes[] to process.c and removing the duplication, resulting in processor_modes[] becoming static. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [PATCH] kexec: Avoid migration of already disabled irqs (ia64)Magnus Damm2007-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes up ia64 kexec support for HP rx2620 hardware. It does this by skipping migration of already disabled irqs. This is most likely a problem on other ia64 platforms as well, but I've only been able to reproduce it on one machine so far. The full story is that handle_bad_irq() gets invoked before starting the new kernel without this patch. This seems to happen when fixup_irqs() calls generic_handle_irq() on already migrated (and disabled) irqs. So by avoiding migration of disabled irqs we stay away of handle_bad_irq(). The code has been tested on three different ia64 machines, all with good results. It is possible to trigger the same bug by offlining a processor using echo 0 > /sys/devices/system/cpu/cpuX/online.

* Revert "[PATCH] fix typo in geode_configre()@cyrix.c"Linus Torvalds2007-02-02
| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit e4f0ae0ea63caceff37a13f281a72652b7ea71ba. It's not wrong, but it's not right either, and everybody seems to agree that the right fix is probably to do the ccr3 write after the ccr4 one (and that we also should clean it up a bit). And after that we need to really validate that all the bits that we write to ccr4 actually do work. The old 2.6.19 code was insane, and basically didn't change ccr4 at all (even though it certainly looks like it was the *intent* to do so). So let's revert the change that may fix things, just because it's not what was actually ever tested when the code was written, even if it _was_ the intent. There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was started by the patch that now gets reverted, and that discussion may well contain the proper long-term fix.

* [PATCH] __crc_... is intended to be absoluteAl Viro2007-02-01
| | | | | | | | | | | | | | | | | | | i386 boot/compressed/relocs checks for absolute symbols and warns about unexpected ones. If you build with modversions, you get ~2500 warnings about __crc_<symbol>. These suckers are really absolute symbols - we do _not_ want to modify them on relocation. They are generated by genksyms - EXPORT_... generates a weak alias, then genksyms produces an ld script with __crc_<symbol> = <checksum> and it's fed to ld to produce the final object file. Their only use is to match kernel and module at modprobe time; they _must_ be absolute. boot/compressed/relocs has a whitelist of known absolute symbols, but it doesn't know about __crc_... stuff. As the result, we get shitloads of false positives on any ld(1) version. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | [PATCH] i386: In assign_irq_vector look at all vectors before giving upEric W. Biederman2007-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the world was a simple and static place setting up irqs was easy. It sufficed to allocate a linux irq number and a find a free cpu vector we could receive that linux irq on. In those days it was a safe assumption that any allocated vector was actually in use so after one global pass through all of the vectors we would have none left. These days things are much more dynamic with interrupt controllers (in the form of MSI or MSI-X) appearing on plug in cards and linux irqs appearing and disappearing. As these irqs come and go vectors are allocated and freed, invalidating the ancient assumption that all allocated vectors stayed in use forever. So this patch modifies the vector allocator to walk through every possible vector before giving up, and to check to see if a vector is in use before assigning it. With these changes we stop leaking freed vectors and it becomes possible to allocate and free irq vectors all day long. This changed was modeled after the vector allocator on x86_64 where this limitation has already been removed. In essence we don't update the static variables that hold the position of the last vector we allocated until have successfully allocated another vector. This allows us to detect if we have completed one complete scan through all of the possible vectors. Acked-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patchs allows the offset to the first page of physical memory to be on any 2MB boundary whereas the previous code could only handle psysical offset to any 16MB boundary (0xNN000000) or any 1MB boundary below 0x01000000 (e.g. 0x00N00000). The problem is a consequence of the orr one-byte syntax, so we fix this and we can place the first bank of memory at 0x28e00000. I have also included an explicit check that disallow compilation when PHYS_OFFSET is not on a 2MiB boundary. head.S would be the proper place to have this at since this is the first file that attempts to use PHYS_OFFSET during compile.

* | | [SPARC64]: Set g4/g5 properly in sun4v dtlb-prot handling.David S. Miller2007-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mirror the logic in the sun4u handler, we have to update both registers even when we branch out to window fault fixup handling. The way it works is that if we are in etrap processing a fault already, g4/g5 holds the original fault information. If we take a window spill fault while doing etrap, then we put the window spill fault info into g4/g5 and this is what the top-level fault handler ends up processing first. Then we retry the originally faulting instruction, and process the original fault at that time. This is all necessary because of how constrained the trap registers are in these code paths. These cases trigger very rarely, so even if there is some performance implication it's doesn't happen very often. In fact the rarity is why it took so long to trigger and find this particular bug.
