Since assign_irq_vector() can be called at runtime, its access of static variables should be protected by a lock. Signed-off-by:

- Factor out the duplicated access/cache code into a single file * Shared between i386/x86-64. - Share flush code between AGP and IOMMU * Fix a bug: AGP didn't wait for end of flush before - Drop 8 northbridges limit and allocate dynamically - Add lock to serialize AGP and IOMMU GART flushes - Add PCI ID for next AMD northbridge - Random related cleanups The old K8 NUMA discovery code is unchanged. New systems should all use SRAT for this. Cc: "Navin Boppuri" <navin.boppuri@newisys.com> Cc: Dave Jones <davej@redhat.com> Signed-off-by:

A trivial change to have gart_unmap_sg call gart_unmap_single directly, instead of bouncing through the dma_unmap_single wrapper in dma-mapping.h. This change required moving the gart_unmap_single above gart_unmap_sg, and under gart_map_single (which seems a more logical place that its current location IMHO). Signed-off-by:

Previously we would just silently provide 64 bit services for this to 32bit processes. I also added all the other cases explicitely to the ptrace compat wrapper to make sure this doesn't happen again. And removed one bogus check in the wrapper. Signed-off-by:

Allow search for a contiguous block of iommu space to cross the next_bit marker if we have already committed ourselves to flushing the gart. There shouldn't be any reason why we'd restrict the search. Signed-off-by:

Replace hard coded DMA masks with #defines from include/linux/dma-mapping.h Signed-off-by:
-
Gerd Hoffmann authored
Changes are largely identical to the i386 version: * alternative #define are moved to the new alternative.h file. * one new elf section with pointers to the lock prefixes which can be nop'ed out for non-smp. * two new elf sections simliar to the "classic" alternatives to replace SMP code with simpler UP code. * fixup headers to use alternative.h instead of defining their own LOCK / LOCK_PREFIX macros. The patch reuses the i386 version of the alternatives code to avoid code duplication. The code in alternatives.c was shuffled around a bit to reduce the number of #ifdefs needed. It also got some tweaks needed for x86_64 (vsyscall page handling) and new features (noreplacement option which was x86_64 only up to now). Debug printk's are changed from compile-time to runtime. Loosely based on a early version from Bastian Blank <waldi@debian.org> Signed-off-by:

Intel systems report the cache level data from CPUID 4 in sysfs. Add a CPUID 4 emulation for AMD CPUs to report the same information for them. This allows programs to read this information in a uniform way. The AMD way to report this is less flexible so some assumptions are hardcoded (e.g. no L3) Signed-off-by:

Previously the apicid<->coreid split was computed based on the max number of cores. Now use a new CPUID AMD defined for that. On most systems right now it should be 0 and the old method will be used. Signed-off-by:

vSMPowered systems use apic_cluster too. Forcing apic_physflat works on these systems too, but only if we change phys_pkg_id to use hard_smp_prcoessor_id() instead of cpuid_ebx. I am guessing other multichassi cluster systems would need this too. Signed-off-by:

binfmt_flat.c calls set_personality with PER_LINUX as the personality. On the arm architecture this results in the program running in 26bit usermode. PER_LINUX_32BIT should be used instead. This doesn't affect other architectures that use binfmt_flat. Signed-off-by:

Here is a patch to the system call handling for 5307/5272/etc to: - fix the strace support (one tested the wrong bit) - make all system calls a little bit faster by inlining set_esp0 and supporting ENOSYS out of the critical path. - remove extraneous spaces Signed-off-by:

This patch solve a bug triggered by execvp (this function use calloc to store the argument list and gcc 3.4.x align the stack to word, not to dword). This situation aren't related to signal handling and all 2.6.x have the bug. On ColdFire targets we must force the stack to be aligned.
