2007-08-31x86: be even more careful about checking the stack frame on dumpingLinus Torvalds1-12/+21
lguest didn't initialize the kernel stack the way a real i386 kernel does, and ended up triggering a corner-case in the stack frame checking that doesn't happen on naive i386, and that the stack dumping didn't handle quite right. This makes the frame handling more correct, and tries to clarify the code at the same time so that it's a bit more obvious what is going on.

The VESA BIOS is specified to be register-clean. However, we have now found at least one system which violates that. Thus, be as paranoid about VESA calls as about everything else.

2007-08-31hugepage: fix broken check for offset alignment in hugepage mappingsDavid Gibson3-6/+4
For hugepage mappings, the file offset, like the address and size, needs to be aligned to the size of a hugepage. In commit 68589bc353037f233fe510ad9ff432338c95db66, the check for this was moved into prepare_hugepage_range() along with the address and size checks. But since BenH's rework of the get_unmapped_area() paths leading up to commit 4b1d89290b62bb2db476c94c82cf7442aab440c8, prepare_hugepage_range() is only called for MAP_FIXED mappings, not for other mappings. This means we're no longer ever checking for an aligned offset - I've confirmed that mmap() will (apparently) succeed with a misaligned offset on both powerpc and i386 at least. This patch restores the check, removing it from prepare_hugepage_range() and putting it back into hugetlbfs_file_mmap(). I'm putting it there, rather than in the get_unmapped_area() path so it only needs to go in one place, than separately in the half-dozen or so arch-specific implementations of hugetlb_get_unmapped_area().

2007-08-31uml: fix x86_64 core dump crashJeff Dike2-6/+15
Stop UML crashing when trying to dump a process core on x86_64. This is the minimal fix to stop the crash - more things are broken here, and patches are forthcoming. The immediate thing to do is define ELF_CORE_COPY_REGS and ELF_CORE_COPY_FPREGS. Defining ELF_CORE_COPY_FPREGS allows dump_fpu to go away. It is defined in terms of save_fp_registers, so that needs to be added.

2007-08-30[SPARC64]: Fix several bugs in MSI handling.David S. Miller3-14/+30
1) sun4{u,v}_build_msi() have improper return value handling. We should always return negative error codes, instead of using the magic value "0" which could in fact be a valid MSI number. 2) sun4{u,v}_build_msi() should return -ENOMEM instead of calling prom_prom() halt with kzalloc() of the interrupt data fails. 3) We 'remembered' the MSI number using a singleton in the struct device archdata area, this doesn't work for MSI-X which can cause multiple MSIs assosciated with one device. Delete that archdata member, and instead store the MSI number in the IRQ chip data area. Signed-off-by: David S. Miller <[email protected]>

2007-08-30[POWERPC] spufs: Don't call spu_run_init from spu_reacquire_runnableAndre Detsch1-5/+1
This fixes a major bug which was happening when a SPU thread advances its execution right after being restored to a SPU. A potentially outdated NPC value was being (re)written to the SPU. So, spu_run_init, in this case, was either not doing anything relevant, or breaking the execution of the SPU thread. This fixes a common problem of losing a mailbox write when it was done to a saved context.

2007-08-30[POWERPC] spufs: Fix update of mailbox status register during backed wbox writeArnd Bergmann1-1/+2
When a process writes into the inbound spu mailbox (wbox) while the context is saved, we accidentally break the contents of the mb_stat_R register by clearing other entries of the mailbox status register. This can cause the user side to hang. This change fixes the problem by only altering the appropriate bits of the mailbox status register during a backing-store write.

2007-08-30[POWERPC] spu_manage: fix spu_unit_number for celleb device treeChristian Krafft1-0/+8
This fixes a regression introduced with 2.6.23-rc4 after on some confusion about the device tree interfaces. IBM QS21 device trees provide "physical-id", so we changed the code to run on that and remain compatible with all IBM machines. However, the Toshiba Celleb device tree provides the "unit-id" property, which was in the Linux code, but never used in this way on IBM hardware. Legacy device tree used the reg property for the physical id of an spe. This patch fixes find_spu_unit_number to look for the spu id in that order. The length is checked to avoid misinterpretation in case the attributes unit-id or reg do not contain the id.

2007-08-28[POWERPC] Flush registers to proper task contextKumar Gala1-3/+3
When we flush register state for FP, Altivec, or SPE in flush_*_to_thread we need to respect the task_struct that the caller has passed to us. Most cases we are called with current, however sometimes (ptrace) we may be passed a different task_struct. This showed up when using gdbserver debugging a simple program that used floating point. When gdb tried to show the FP regs they all showed up as 0, because the child's FP registers were never properly flushed to memory. Signed-off-by: Kumar Gala <[email protected]>
2007-08-28[IA64] Clear pending interrupts at CPU boot up timeKenji Kaneshige1-0/+5

Fix handling for spurious interrupts not being mapped to any IRQs. Currently, spurious interrupts that are not mapped to any IRQs are handled as IRQ 15 (== IA64_SPURIOUS_VECTOR). But it is not proper because vector != irq. We need special handlings for such spurious interrupts not being mapped to any IRQs.

2007-08-27[XTENSA] Add support for cache-aliasingChris Zankel7-290/+624
Add support for processors that have cache-aliasing issues, such as the Stretch S5000 processor. Cache-aliasing means that the size of the cache (for one way) is larger than the page size, thus, a page can end up in several places in cache depending on the virtual to physical translation. The method used here is to map a user page temporarily through the auto-refill way 0 and of of the DTLB. We probably will want to revisit this issue and use a better approach with kmap/kunmap.
