powerpc: Add new CPU feature: CPU_FTR_CP_USE_DCBTZ

2008-09-15T18:07:38Z

Add a new CPU feature bit, CPU_FTR_CP_USE_DCBTZ, to be added to the 64bit powerpc chips that benefit from having dcbt and dcbz instructions used in their memory copy routines. This will be used in a subsequent patch that updates copy_4K_page(). The new bit is added to Cell, PPC970 and Power4 because they show better performance with the new copy_4K_page() when dcbt and dcbz instructions are used.

powerpc: Expose PMCs & cache topology in sysfs on 32-bit

2008-08-20T06:34:58Z

The file arch/powerpc/kernel/sysfs.c is currently only compiled for 64-bit kernels. It contain code to register CPU sysdevs in sysfs and add various properties such as cache topology and raw access by root to performance monitor counters (PMCs). A lot of that can be re-used as is on 32-bits. This makes the file be built for both, with appropriate ifdef'ing for the few bits that are really 64-bit specific, and adds some support for the raw PMCs for 75x and 74xx processors.

powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00Z

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras
