2010-05-11kprobes/x86: Fix removed int3 checking orderMasami Hiramatsu
Fix kprobe/x86 to check removed int3 when failing to get kprobe from hlist. Since we have a time window between checking int3 exists on probed address and getting kprobe on that address, we can have following scenario: ------- CPU1 CPU2 hit int3 check int3 exists remove int3 remove kprobe from hlist get kprobe from hlist no kprobe->OOPS! ------- This patch moves int3 checking if there is no kprobe on that address for fixing this problem as follows: ------ CPU1 CPU2 hit int3 remove int3 remove kprobe from hlist get kprobe from hlist no kprobe->check int3 exists ->rollback&retry ------ Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Acked-by: Ananth N Mavinakayanahalli <ananth@in.ibm.com> Cc: systemtap <systemtap@sources.redhat.com> Cc: DLE <dle-develop@lists.sourceforge.net> Cc: Dave Anderson <anderson@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <20100427223348.2322.9112.stgit@localhost6.localdomain6> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2010-05-06microblaze: Optimize CACHE_LOOP_LIMITS and CACHE_RANGE_LOOP macrosMichal Simek
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.

2010-05-06microblaze: Define correct L1_CACHE_SHIFT valueMichal Simek
Microblaze cacheline length is configurable and current cpu uses two cacheline length 4 and 8. We are taking conservative maximum value to be sure that cacheline alignment is satisfied for all cases. Here is the calculation for cacheline lenght 8 32bit=4Byte values which is corresponding with SHIFT 5. Signed-off-by: Michal Simek <monstr@monstr.eu>

2010-05-06microblaze: Remove "cache" optimized copy_page functionMichal Simek
Current implementation doesn't handle dcache_line_length correctly that's why is better to use generic memcpy. Cache optimized function could be good way howto improve performance but must be based on benchmarking not blind function like this. Signed-off-by: Michal Simek <monstr@monstr.eu>
