microblaze: Fix build with make 3.82

2011-04-17T20:15:37Z

commit b843e4ec01991a386a9e0e9030703524446e03da upstream. When running make headers_install_all on x86_64 and make 3.82 I hit this: arch/microblaze/Makefile:80: *** mixed implicit and normal rules. Stop. make: *** [headers_install_all] Error 2 So split the rules to satisfy make 3.82. Signed-off-by: Thomas Backlund Signed-off-by: Michal Simek Signed-off-by: Paul Gortmaker

microblaze: Fix module loading on system with WB cache

microblaze: fix get_user/put_user side-effects

2010-05-13T07:21:14Z

The Microblaze implementations of get_user() and (MMU) put_user() evaluate the address argument more than once. This causes unexpected side-effects for invocations that include increment operators, i.e. get_user(foo, bar++). This patch also removes the distinction between MMU and noMMU put_user(). Without the patch: $ echo 1234567890 > /proc/sys/kernel/core_pattern $ cat /proc/sys/kernel/core_pattern 12345 Signed-off-by: Steven J. Magnani

microblaze: Optimize CACHE_LOOP_LIMITS and CACHE_RANGE_LOOP macros

2010-05-06T09:22:00Z

1. Remove CACHE_ALL_LOOP2 macro because it is identical to CACHE_ALL_LOOP 2. Change BUG_ON to WARN_ON 3. Remove end aligned from CACHE_LOOP_LIMITS. C implementation do not need aligned end address and ASM code do aligned in their macros 4. ASM optimized CACHE_RANGE_LOOP_1/2 macros needs to get aligned end address. Because end address is compound from start + size, end address is the first address which is exclude. Here is the corresponding code which describe it. + int align = ~(line_length - 1); + end = ((end & align) == end) ? end - line_length : end & align; a) end is aligned: it is necessary to subtruct line length because we don't want to work with next cacheline b) end address is not aligned: Just align it to be ready for ASM code.
