2015-10-22ACPICA: Debugger: Fix "terminate" command by cleaning up subsystem shutdown ↵Lv Zheng3-14/+15
logic ACPICA commit 7e823714911480be47e310fb1b3590d289b9fd99 Segmentation fault can be seen for executing the "terminate" command. This is because acpi_ut_subsystem_shutdown() is errnously called multiple times. This patch cleans up acpi_ut_subsystem_shutdown() logics to fix this issue. Lv Zheng.

2015-10-22ACPICA: Debugger: Fix "quit/exit" command by cleaning up user commands ↵Lv Zheng5-19/+26
termination logic ACPICA commit 0dd68e16274cd38224aa4781eddc57dc2cbaa108 The quit/exit commands shouldn't invoke acpi_terminate_debugger() and acpi_terminate() right in the user command loop, because when the debugger exits, the kernel ACPI subsystem shouldn't be terminated (acpi_terminate()) and the debugger should only be terminated by its users (acpi_terminate_debugger()) rather than being terminated itself. Leaving such invocations causes kernel panic when the debugger is shipped in the Linux kernel. This patch fixes this issue. Lv Zheng.

2015-10-22ACPICA: Debugger: Update mutexes used for multithreaded debuggerBob Moore5-8/+28
ACPICA commit 6b2701f619040e803313363f516b200e362a9100 Make these mutex objects independent of the deadlock detection mechanism. This mechanism caused failures with the multithread debugger. This patch doesn't affect Linux kernel as debugger is currently not fully functioning in the Linux kernel. And the further debugger cleanups will take care of handling debugger command signalling correctly instead of using such kind of mutexes. So it is safe to leave this patch as it is.

ACPICA commit ac1564c26d239348ef13455f61d5616f3961ff43 Used by the ACPICA applications. This patch is a bit broken due to non-portable <errno.h> inclusion as on some platforms, there is no such a header file for their lib-c exports. Fortunately, Linux doesn't compile utfileio.c for either the kernel space ACPICA core (drivers/acpi/acpica) or the userspace ACPICA tools (tools/power/acpi) for now, so it's safe to leave this patch as it is.

2015-10-14ACPICA: Tables: Fix FADT dependency regressionLv Zheng5-33/+10
Some logics actually relying on the existence of FADT, currently relies on the number of loaded tables. This false dependency can easily trigger regressions. One of them has been introduced by commit 8ec3f459073e (ACPICA: Tables: Fix global table list issues by removing fixed table). The commit changing the fixed table indexes results in the change of FADT table index, originally, it was 3 (thus the installed table count should be greater than 4), while currently it is 0 (and the installed table count may be 3). This patch fixes this regression by cleaning up the code. Lv Zheng.

2015-10-10namei: results of d_is_negative() should be checked after dentry revalidationTrond Myklebust1-2/+6
Leandro Awa writes: "After switching to version 4.1.6, our parallelized and distributed workflows now fail consistently with errors of the form: T34: ./regex.c:39:22: error: config.h: No such file or directory From our 'git bisect' testing, the following commit appears to be the possible cause of the behavior we've been seeing: commit 766c4cbfacd8" Al Viro says: "What happens is that 766c4cbfacd8 got the things subtly wrong. We used to treat d_is_negative() after lookup_fast() as "fall with ENOENT". That was wrong - checking ->d_flags outside of ->d_seq protection is unreliable and failing with hard error on what should've fallen back to non-RCU pathname resolution is a bug. Unfortunately, we'd pulled the test too far up and ran afoul of another kind of staleness. The dentry might have been absolutely stable from the RCU point of view (and we might be on UP, etc), but stale from the remote fs point of view. If ->d_revalidate() returns "it's actually stale", dentry gets thrown away and the original code wouldn't even have looked at its ->d_flags. What we need is to check ->d_flags where 766c4cbfacd8 does (prior to ->d_seq validation) but only use the result in cases where we do not discard this dentry outright" Reported-by: Leandro Awa <lawa@nvidia.com> Link: https://bugzilla.kernel.org/show_bug.cgi?id=104911 Fixes: 766c4cbfacd8 ("namei: d_is_negative() should be checked...")

2015-10-09dm snapshot: add new persistent store option to support overflowMike Snitzer6-18/+37
Commit 76c44f6d80 introduced the possibly for "Overflow" to be reported by the snapshot device's status. Older userspace (e.g. lvm2) does not handle the "Overflow" status response. Fix this incompatibility by requiring newer userspace code, that can cope with "Overflow", request the persistent store with overflow support by using "PO" (Persistent with Overflow) for the snapshot store type.

2015-10-09genirq: Export handle_bad_irqArnd Bergmann1-0/+1
A cleanup of the omap gpio driver introduced a use of the handle_bad_irq() function in a device driver that can be a loadable module. This broke the ARM allmodconfig build: ERROR: "handle_bad_irq" [drivers/gpio/gpio-omap.ko] undefined! This patch exports the handle_bad_irq symbol in order to allow the use in modules.

2015-10-09dm cache: fix NULL pointer when switching from cleaner policyJoe Thornber1-1/+1
The cleaner policy doesn't make use of the per cache block hint space in the metadata (unlike the other policies). When switching from the cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block) was observed. The crash was caused by bugs in dm-cache-metadata.c when trying to skip creation of the hint btree. The minimal fix is to change hint size for the cleaner policy to 4 bytes (only hint size supported).

2015-10-09crash in md-raid1 and md-raid10 due to incorrect list manipulationMikulas Patocka2-4/+4
The commit 55ce74d4bfe1b9444436264c637f39a152d1e5ac (md/raid1: ensure device failure recorded before write request returns) is causing crash in the LVM2 testsuite test shell/lvchange-raid.sh. For me the crash is 100% reproducible. The reason for the crash is that the newly added code in raid1d moves the list from conf->bio_end_io_list to tmp, then tests if tmp is non-empty and then incorrectly pops the bio from conf->bio_end_io_list (which is empty because the list was alrady moved). Raid-10 has a similar bug.

The Atmel sdhci device needs a new quirk. sdhci_set_clock set the Clock Control Register to 0 before computing the new value and writing it. It disables the internal clock which causes a reset mecanism. If we write the new value before this reset mecanism is done, it will prevent the stabilisation of the internal clock, so a delay is needed. This delay is about 2-3 cycles of the base clock. To be safe, a 1 ms delay is used. Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
