2013-09-11drivers/rtc/rtc-omap.c: add rtc wakeup support to alarm eventsHebbar Gururaja2-9/+57
On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN) is available to enable Alarm Wakeup feature. This register needs to be properly handled for the rtcwake to work properly. Platforms using such IP should set "ti,am3352-rtc" in rtc device dt compatibility node.

2013-09-11s390/kprobes: add support for pc-relative long displacement instructionsHeiko Carstens2-8/+140
With the general-instruction extension facility (z10) a couple of instructions with a pc-relative long displacement were introduced. The kprobes support for these instructions however was never implemented. In result, if anybody ever put a probe on any of these instructions the result would have been random behaviour after the instruction got executed within the insn slot. So lets add the missing handling for these instructions. Since all of the new instructions have 32 bit signed displacement the easiest solution is to allocate an insn slot that is within the same 2GB area like the original instruction and patch the displacement field.

2013-09-11kprobes: allow to specify custom allocator for insn cachesHeiko Carstens2-2/+20
The current two insn slot caches both use module_alloc/module_free to allocate and free insn slot cache pages. For s390 this is not sufficient since there is the need to allocate insn slots that are either within the vmalloc module area or within dma memory. Therefore add a mechanism which allows to specify an own allocator for an own insn slot cache.

2013-09-11kprobes: unify insn cachesHeiko Carstens2-58/+49
The current kpropes insn caches allocate memory areas for insn slots with module_alloc(). The assumption is that the kernel image and module area are both within the same +/- 2GB memory area. This however is not true for s390 where the kernel image resides within the first 2GB (DMA memory area), but the module area is far away in the vmalloc area, usually somewhere close below the 4TB area. For new pc relative instructions s390 needs insn slots that are within +/- 2GB of each area. That way we can patch displacements of pc-relative instructions within the insn slots just like x86 and powerpc. The module area works already with the normal insn slot allocator, however there is currently no way to get insn slots that are within the first 2GB on s390 (aka DMA area). Therefore this patch set modifies the kprobes insn slot cache code in order to allow to specify a custom allocator for the insn slot cache pages. In addition architecure can now have private insn slot caches withhout the need to modify common code. Patch 1 unifies and simplifies the current insn and optinsn caches implementation. This is a preparation which allows to add more insn caches in a simple way. Patch 2 adds the possibility to specify a custom allocator. Patch 3 makes s390 use the new insn slot mechanisms and adds support for pc-relative instructions with long displacements. This patch (of 3): The two insn caches (insn, and optinsn) each have an own mutex and alloc/free functions (get_[opt]insn_slot() / free_[opt]insn_slot()). Since there is the need for yet another insn cache which satifies dma allocations on s390, unify and simplify the current implementation: - Move the per insn cache mutex into struct kprobe_insn_cache. - Move the alloc/free functions to kprobe.h so they are simply wrappers for the generic __get_insn_slot/__free_insn_slot functions. The implementation is done with a DEFINE_INSN_CACHE_OPS() macro which provides the alloc/free functions for each cache if needed. - move the struct kprobe_insn_cache to kprobe.h which allows to generate architecture specific insn slot caches outside of the core kprobes code.

2013-09-11firmware/dmi_scan: drop OOM messagesJean Delvare1-17/+6
As reported by Joe Perches: OOM messages generally aren't useful. dmi_alloc is either a trivial front-end to kzalloc, and kzalloc already does a dump_stack() when OOM, or for x86, dmi_alloc uses extend_brk which BUGs when unsuccessful. So we can remove all 6 such log messages in the dmi_scan driver, to shrink the binary size (by 528 bytes on x86_64.)

2013-09-11checkpatch: add test for positional misuse of section specifiers like __initdataJoe Perches1-1/+46
As discussed recently on the arm [1] and lm-sensors [2] lists, it is possible to use section markers on variables in a way which gcc doesn't understand (or at least not the way the developer intended): static struct __initdata samsung_pll_clock exynos4_plls[nr_plls] = { does NOT put exynos4_plls in the .initdata section. The __initdata marker can be virtually anywhere on the line, EXCEPT right after "struct". The preferred location is before the "=" sign if there is one, or before the trailing ";" otherwise. [1] http://permalink.gmane.org/gmane.linux.ports.arm.kernel/258149 [2] http://lists.lm-sensors.org/pipermail/lm-sensors/2013-August/039836.html So, update checkpatch to find these misuses and report an error when it's immediately after struct or union, and a warning when it's otherwise not immediately before the ; or =.

2013-09-11checkpatch: reduce runtime/cpu time usedJoe Perches1-1/+3
There are some cases where checkpatch can take a long time to complete. Reduce the likelihood of this long run-time by adding a new test for lines with and without comments and eliminating checks on lines with only comments. This reduces the number of "ctx_statement_block" calls, and also the number of tests of $stat, which is now undefined for these blank lines. One test in particular, the "check for switch/default statements without a break", could take an extremely long time to parse as it tries to skip interleaving comments within the ctx_statement_block/$stat and that could be done multiple times unnecessarily. A small test case taken from cfg80211.h before this patch would take 1000's of seconds to run, now it's just a couple seconds.

2013-09-11checkpatch: enforce sane perl versionDave Hansen1-0/+12
I got a bug report from a couple of users who said checkpatch.pl was broken for them. It was erroring out on fairly random lines most commonly with messages like: Nested quantifiers in regex; marked by <--HERE in m/(\((?:[^\(\)]++ <-- HERE |(?-1))*\))/ at ./checkpatch.pl line 340. The bug reporter was running a version of perl 5.8 which was end-of-lifed in 2008: http://www.cpan.org/src/. Versions of perl this old are at _best_ quite untested. At worst, they are crusty and known to be completely broken. If folks have a system _that_ old, then we should have mercy on them and give them a half-decent error message rather than fail with nutty error messages. This patch enforces that checkpatch.pl is run with perl 5.10, which was end-of-lifed in 2009. The new --ignore-perl-version command-line switch will let folks override this if they want.

2013-09-11checkpatch: check CamelCase by word, not by $LvalJoe Perches1-5/+9
$Lval is a test for complete name (ie: foo->bar.Baz[1]) If any of this is CamelCase, then the current test uses the entire $Lval. This isn't optimal because it can emit messages with foo->bar.Baz and bar.Baz when Baz is a variable specified in an include file. So instead, break the $Lval into words and check each word for CamelCase uses.

2013-09-11lib/decompressors: fix "no limit" output buffer lengthAlexandre Courbot1-1/+1
When decompressing into memory, the output buffer length is set to some arbitrarily high value (0x7fffffff) to indicate the output is, virtually, unlimited in size. The problem with this is that some platforms have their physical memory at high physical addresses (0x80000000 or more), and that the output buffer address and its "unlimited" length cannot be added without overflowing. An example of this can be found in inflate_fast(): /* next_out is the output buffer address */ out = strm->next_out - OFF; /* avail_out is the output buffer size. end will overflow if the output * address is >= 0x80000104 */ end = out + (strm->avail_out - 257); This has huge consequences on the performance of kernel decompression, since the following exit condition of inflate_fast() will be always true: } while (in < last && out < end); Indeed, "end" has overflowed and is now always lower than "out". As a result, inflate_fast() will return after processing one single byte of input data, and will thus need to be called an unreasonably high number of times. This probably went unnoticed because kernel decompression is fast enough even with this issue. Nonetheless, adjusting the output buffer length in such a way that the above pointer arithmetic never overflows results in a kernel decompression that is about 3 times faster on affected machines.

2013-09-11task_work: minor cleanupsOleg Nesterov1-2/+2
Trivial. Remove the unnecessary "work = NULL" initialization and turn read_barrier_depends() into smp_read_barrier_depends() in task_work_cancel(). Signed-off-by: Oleg Nesterov <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2013-09-11kernel/smp.c: quit unconditionally enabling irqs in on_each_cpu_mask().David Daney1-4/+7
As in commit f21afc25f9ed ("smp.h: Use local_irq_{save,restore}() in !SMP version of on_each_cpu()"), we don't want to enable irqs if they are not already enabled. I don't know of any bugs currently caused by this unconditional local_irq_enable(), but I want to use this function in MIPS/OCTEON early boot (when we have early_boot_irqs_disabled). This also makes this function have similar semantics to on_each_cpu() which is good in itself.

2013-09-11extable: skip sorting if the table is emptyUwe Kleine-König1-1/+1
At least on ARM no-MMU the extable is empty and so there is nothing to sort. So add a check for the table to be empty which effectively only changes that the misleading pr_notice is suppressed.
