* kcore: use registerd physmem informationKAMEZAWA Hiroyuki2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | For /proc/kcore, each arch registers its memory range by kclist_add(). In usual, - range of physical memory - range of vmalloc area - text, etc... are registered but "range of physical memory" has some troubles. It doesn't updated at memory hotplug and it tend to include unnecessary memory holes. Now, /proc/iomem (kernel/resource.c) includes required physical memory range information and it's properly updated at memory hotplug. Then, it's good to avoid using its own code(duplicating information) and to rebuild kclist for physical memory based on /proc/iomem.

* kcore: register vmalloc area in generic wayKAMEZAWA Hiroyuki2009-09-23
| | | | | | | | | | | | | | For /proc/kcore, vmalloc areas are registered per arch. But, all of them registers same range of [VMALLOC_START...VMALLOC_END) This patch unifies them. By this. archs which have no kclist_add() hooks can see vmalloc area correctly.

* kcore: add kclist typesKAMEZAWA Hiroyuki2009-09-23
| | | | | | | | | | | | | | | | | | | | | Presently, kclist_add() only eats start address and size as its arguments. Considering to make kclist dynamically reconfigulable, it's necessary to know which kclists are for System RAM and which are not. This patch add kclist types as KCORE_RAM KCORE_VMALLOC KCORE_TEXT KCORE_OTHER This "type" is used in a patch following this for detecting KCORE_RAM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

In order for SH7709 to fully support the varying clock modes, it needs to implement a more complete clock framework. After this change it is in sync with legacy CPG mode, which ends up being the default configuration for this CPU anyways.

Unfortunately we can't use on_each_cpu() for all of the cache ops, as some of them only require preempt disabling.

A bit of special magic is needed in the interrupt exception path given that the NMI exception handler is stubbed in to the regular exception handling table despite being reported in INTEVT. So we mangle the lookup and kick off an EXPEVT-style exception dispatch from the INTEVT path for exceptions that do_IRQ() has no chance of handling. As a result, we also drop the evt2irq() conversion from the do_IRQ() path and just do it in assembly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | * | sh: Fix dcache flushing for N-way write-through caches.Matt Fleming2009-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adopts the special-cased 2-way write-through dcache flusher for N-ways and moves it in to the generic path. Assignment is done at runtime via the check for the CCR_CACHE_WT bit in the same path as the per-way writeback flushers.

| | * | sh: Only shout about fixing up unexpected unaligned accessesMatt Fleming2009-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some unaligned accesses are completely expected. For example, the trapped_io code uses the unaligned access fixup code path so there's no need to warn about having to fixup the unaligned access.
