* [ARM] fix fls() for 64-bit argumentsAndrew Morton2008-07-26
| | | | | | | | | | | arm's fls() is implemented as a macro, causing it to misbehave when passed 64-bit arguments. Fix.

| * remove dummy asm/kvm.h filesAdrian Bunk2008-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the dummy asm/kvm.h files on architectures not (yet) supporting KVM and uses the same conditional headers installation as already used for a.out.h . Also removed are superfluous install rules in the s390 and x86 Kbuild files (they are already in Kbuild.asm).

* | include/asm/ptrace.h userspace headers cleanupAdrian Bunk2008-07-25

* | PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-24
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

This driver implements the DMA engine API and supports the following capabilities: - memcpy - xor - memset The XOR engine can be used by DMA engine clients implemented in the kernel, one of those clients is the RAID module. In that case, I observed 20% improvement in the raid5 write throughput, and 40% decrease in the CPU utilization when doing array construction, those results obtained on an 5182 running at 500Mhz. When enabling the NET DMA client, the performance decreased, so meanwhile it is recommended to keep this client off.

Geoff Levand <geoffrey.levand@am.sony.com>, Nicolas Pitre, Manish Lachwani, and Jason Wessel have contributed various fixups here as well. The KGDB patch makes one change to the core ARM architecture such that the traps are initialized early for use with the debugger or other subsystems.
