| * | 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.

| * Blackfin: fix framebuffer mmap bug for nommuThomas Chou2009-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch added a special get_unmapped_area for framebuffer which was hooked to the file ops in drivers/video/fbmem.c. This is needed since v2.6.29-rc1 where nommu vma management was updated, and mmap of framebuffer caused kernel BUG panic. You may turn on "Debug the global anon/private NOMMU mapping region tree" config to such message. As Documentation/nommu-mmap.txt said, "To provide shareable character device support, a driver must provide a file->f_op->get_unmapped_area() operation. The mmap() routines will call this to get a proposed address for the mapping." With this change, user space should call mmap for framebuffer using shared map. Or it can try shared map first, then private map if failed. This shared map usage is now consistent between mmu and nommu. The sys_ file may not be a good place for this patch. But there is a similar one for sparc. I tested a similar patch on nios2nommu, though I don't have a blackfin board to test.

* | net: Introduce recvmmsg socket syscallArnaldo Carvalho de Melo2009-10-13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Meaning receive multiple messages, reducing the number of syscalls and net stack entry/exit operations. Next patches will introduce mechanisms where protocols that want to optimize this operation will provide an unlocked_recvmsg operation. This takes into account comments made by: . Paul Moore: sock_recvmsg is called only for the first datagram, sock_recvmsg_nosec is used for the rest. . Caitlin Bestler: recvmmsg now has a struct timespec timeout, that works in the same fashion as the ppoll one. If the underlying protocol returns a datagram with MSG_OOB set, this will make recvmmsg return right away with as many datagrams (+ the OOB one) it has received so far. . Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen datagrams and then recvmsg returns an error, recvmmsg will return the successfully received datagrams, store the error and return it in the next call. This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg, where we will be able to acquire the lock only at batch start and end, not at every underlying recvmsg call.

The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

* / perf: Do the big rename: Performance Counters -> Performance EventsIngo Molnar2009-09-21

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.

* Blackfin: swap clocksource ratings for gptimer/cyclesGraf Yang2009-09-16
| | | | | | | | The cycles clocksource is a higher resolution than the gptimer one, so make sure the ratings field reflects this. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: update ftrace_push_return_trace() breakageMike Frysinger2009-09-16
| | | | | | | | Commit 71e308a239c updated ftrace_push_return_trace() prototype but didn't update the Blackfin ftrace code, so things broke. Since we don't support the new stuff yet, call it with stub values. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: cm-bf537u: split board from cm-bf537eHarald Krapfenbauer2009-09-16
| | | | | | | | The cm-bf537u module, while similar to the cm-bf537e, is different enough to warrant its own resources. It has a USB controller but no PHY. Signed-off-by: Harald Krapfenbauer <Harald.Krapfenbauer@bluetechnix.at> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: increase default async timings for parallel flashesSonic Zhang2009-09-16
| | | | | | | | | The default async timings are a little too fast for the parallel flash that is attached by default to the async banks. So slow things down a bit so accessing the hardware is stable.

* Blackfin: add ICPLB coverage for async banksBernd Schmidt2009-09-16
| | | | | | | | When doing XIP, we need to execute out of the async banks, so we need ICPLBs to allow this. Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: use KERN_ALERT in all kgdb_test outputMingquan Pan2009-09-16
| | | | | | | | Most messages are already using KERN_ALERT, so be consistent to make things easier to check with test scripts. Signed-off-by: Mingquan Pan <grace.pan@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
