| * kbuild: move asm-offsets.h to include/generatedSam Ravnborg2009-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | The simplest method was to add an extra asm-offsets.h file in arch/$ARCH/include/asm that references the generated file. We can now migrate the architectures one-by-one to reference the generated file direct - and when done we can delete the temporary arch/$ARCH/include/asm/asm-offsets.h file.

* | microblaze: Support for WB cacheMichal Simek2009-12-14
| | | | | | | | | | | | | | | | | | | | | | Microblaze version 7.20.d is the first MB version which can be run on MMU linux. Please do not used previous version because they contain HW bug. Based on WB support was necessary to redesign whole cache design. Microblaze versions from 7.20.a don't need to disable IRQ and cache before working with them that's why there are special structures for it. Signed-off-by: Michal Simek <monstr@monstr.eu>

* | microblaze: ftrace: Add dynamic trace supportMichal Simek2009-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With dynamic function tracer, by default, _mcount is defined as an "empty" function, it returns directly without any more action. When enabling it in user-space, it will jump to a real tracing function(ftrace_caller), and do the real job for us. Differ from the static function tracer, dynamic function tracer provides two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the tracing of some indicated kernel functions(set_ftrace_filter). In the kernel version, there is only one "_mcount" string for every kernel function, so, we just need to match this one in mcount_regex of scripts/recordmcount.pl. For more information please look at code and Documentation/trace folder. Steven ACK that scripts/recordmcount.pl part.

* | microblaze: ftrace: add static function tracerMichal Simek2009-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If -pg of gcc is enabled with CONFIG_FUNCTION_TRACER=y. a calling to _mcount will be inserted into each kernel function. so, there is a possibility to trace the kernel functions in _mcount. This patch add the specific _mcount support for static function tracing. by default, ftrace_trace_function is initialized as ftrace_stub(an empty function), so, the default _mcount will introduce very little overhead. after enabling ftrace in user-space, it will jump to a real tracing function and do static function tracing for us.

* | microblaze: Lockdep supportMichal Simek2009-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microblaze needs to do lock_init very soon because MMU init calls lock functions. Here is the explanation from Peter Zijlstra why we have to enable __ARCH_WANTS_INTERRUPTS_ON_CTSW. "So we schedule while holding rq->lock (for obvious reasons), but since lockdep tracks held locks per tasks, we need to transfer the held state from the prev to the next task. We do this by explicity calling spin_release(&rq->lock) in context_switch() right before switch_to(), and calling spin_acquire(&rq->lock) in finish_task_switch()->finish_lock_switch(). Now, for some reason lockdep thinks that interrupts got enabled over the context switch (git grep __ARCH_WANTS_INTERRUPTS_ON_CTSW arch/microblaze doesn't seem to turn up anything). Clearly trying to acquire the rq->lock with interrupts enabled is a bad idea and lockdep warns you about this." Signed-off-by: Michal Simek <monstr@monstr.eu>

| * block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov2009-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.

* | perf: Do the big rename: Performance Counters -> Performance EventsIngo Molnar2009-09-21
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by: Stephane Eranian <eranian@google.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Paul Mackerras <paulus@samba.org> Reviewed-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Howells <dhowells@redhat.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "David S.

| | * microblaze: Add _PAGE_FILE macros to pgtable.hMichal Simek2009-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | We need to define _PAGE_FILE macro and change pte functions. Microblaze use the same MMU as PowerPC that's why we define _PAGE_FILE in the same style. This change fixed remap_file_pages01 LTP test. Signed-off-by: Michal Simek <monstr@monstr.eu>
| | * microblaze: Fix put_user macro for 64bits argumentsMichal Simek2009-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 64bits arguments gcc caused that put_user macro works with wrong value because of optimalization. Adding volatile caused that gcc not optimized it. It is possible to use (as Blackfin do) two put_user macros with 32bits arguments but there is one more instruction which is due to duplication zero return value which is called put_user_asm macro.

| | * microblaze: Final support for statically linked DTBJohn Williams2009-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | If r7 is zero at kernel boot, or does not point to a valid DTB, then we fall back to a DTB (assumed to be) linked statically in the kernel, instead of blindly copying bogus cruft into the kernel DTB memory region Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

| | * microblaze: Define tlb_flush macroMichal Simek2009-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fix remove bug which we had till now in all Microblaze MMU code. Primary tested on mmap01 LTP test. We forget to flush invalid tlb which were changed - we used them and there were wrong old data which wasn't correct. Signed-off-by: Michal Simek <monstr@monstr.eu>
