| | | | | | | | | | | | | | | | | | | - 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.

* [PATCH] x86_64: trivial gart clean-upJon Mason2006-06-261-23/+23
| | | | | | | | | | | | | | 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).

* [PATCH] x86_64: x86_64 version of the smp alternative patch.Gerd Hoffmann2006-06-267-135/+152
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] i386/x86-64: Emulate CPUID4 on AMDAndi Kleen2006-06-263-13/+105
| | | | | | | | | | | | | 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: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Fix kdump Crash Kernel boot memory reservation for NUMA machinesAmul Shah2006-06-251-1/+1
| | | | | | | | | | | | | | | | | | | | This patch will fix a boot memory reservation bug that trashes memory on the ES7000 when loading the kdump crash kernel. The code in arch/x86_64/kernel/setup.c to reserve boot memory for the crash kernel uses the non-numa aware "reserve_bootmem" function instead of the NUMA aware "reserve_bootmem_generic". I checked to make sure that no other function was using "reserve_bootmem" and found none, except the ones that had NUMA ifdef'ed out. I have tested this patch only on an ES7000 with NUMA on and off (numa=off) in a single (non-NUMA) and multi-cell (NUMA) configurations.

* [PATCH] Make copy_from_user_inatomic NOT zero the tail on i386NeilBrown2006-06-251-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | As described in a previous patch and documented in mm/filemap.h, copy_from_user_inatomic* shouldn't zero out the tail of the buffer after an incomplete copy. This patch implements that change for i386. For the _nocache version, a new __copy_user_intel_nocache is defined similar to copy_user_zeroio_intel_nocache, and this is ultimately used for the copy. For the regular version, __copy_from_user_ll_nozero is defined which uses __copy_user and __copy_user_intel - the later needs casts to reposition the __user annotations. If copy_from_user_atomic is given a constant length of 1, 2, or 4, then we do still zero the destintion on failure. This didn't seem worth the effort of fixing as the places where it is used really don't care.
