2013-04-30ACPI/libata: Restore libata.noacpi supportLv Zheng
This patch restores libata.noacpi support to libata-acpi.c. There are broken optional control methods for ATA controller devices in the real world. The libata.noacpi has been used for a long time as a workaround to deal with issues caused by the broken ASL codes. 1. The "noacpi" option is introduced by the following commit: commit 11ef697b37e3c85ce1ac21f7711babf1f5b12784 Date: Thu, 28 Sep 2006 11:29:01 -0700 Subject: libata: ACPI and _GTF support 2. The "noacpi" option is renamed to "libata_noacpi" by the following commit: commit d7d0dad62a641c156386288a747c1a2f6bb2e42d Date: Wed, 28 Mar 2007 01:57:37 -0400 Subject: [libata] Disable ACPI by default; fix namespace problems 3. Some of its logics are changed over time - becomes relying on the "acpi_handle" bound to the ATA devices since this commit: commit fafbae87db88a73b166d3bc3294d209207f27056 Date: Tue, 15 May 2007 03:28:16 +0900 Subject: libata-acpi: implement ata_acpi_associate() 4. The option is deleted by the following commit: commit 30dcf76acc695cbd2fa919e294670fe9552e16e7 Date: Mon, 25 Jun 2012 16:13:04 +0800 Subject: libata: migrate ACPI code over to new bindings But the libata.noacpi setup is still left in the kernel without codes to implement it. So the deletion introduces a regression to the Linux. This patch disables ATA_ACPI support at runtime by stopping acpi binding on the ATA devices to fix this regression. This patch is tested by booting a SATA x86-64 kernel or a PATA x86 kernel with or without "libata.noacpi=1" kernel command line argument.

2013-04-30[libata] acpi: make ata_ap_acpi_handle not blockAaron Lu
Since commit 30dcf76acc, ata_ap_acpi_handle will always do a namespace walk, which requires acquiring an acpi namespace mutex. This made it impossible to be used when calling path has held a spinlock. For example, it can occur in the following code path for pata_acpi: ata_scsi_queuecmd (ap->lock is acquired) __ata_scsi_queuecmd ata_scsi_translate ata_qc_issue pacpi_qc_issue ata_acpi_stm ata_ap_acpi_handle acpi_get_child acpi_walk_namespace acpi_ut_acquire_mutex (acquire mutex while holding lock) This caused scheduling while atomic bug, as reported in bug #56781. Actually, ata_ap_acpi_handle doesn't have to walk the namespace every time it is called, it can simply return the bound acpi handle on the corresponding SCSI host. The reason previously it is not done this way is, ata_ap_acpi_handle is used in the binding function ata_acpi_bind_host by ata_acpi_gtm when the handle is not bound to the SCSI host yet. Since we already have the ATA port's handle in its binding function, we can simply use it instead of calling ata_ap_acpi_handle there. So introduce a new function __ata_acpi_gtm, where it will receive an acpi handle param in addition to the ATA port which is solely used for debug statement. With this change, we can make ata_ap_acpi_handle simply return the bound handle for SCSI host instead of walking the acpi namespace now.

git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial Pull fixup for trivial branch from Jiri Kosina: "Unfortunately I made a mistake when merging into for-linus branch, and omitted one pre-requisity patch for a few other patches (which have been Acked by the appropriate maintainers) in the series. Mea culpa maxima, sorry for that." The trivial branch added %pSR usage before actually teaching vsnprintf() about the 'R' part of %pSR. The 'R' causes the symbol translation to do a "__builtin_extract_return_addr()" before symbol lookup. That said, on most architectures __builtin_extract_return_addr() isn't likely to do anything special, so it probably is not normally noticeable. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial: vsprintf: Add extension %pSR - print_symbol replacement
2013-04-30vsprintf: Add extension %pSR - print_symbol replacementJoe Perches
print_symbol takes a long and converts it to a function name and offset. %pS does something similar, but doesn't translate the address via __builtin_extract_return_addr. %pSR does the translation. This will enable replacing multiple calls like printk(...); printk_symbol(addr); printk("\n"); with a single non-interleavable in dmesg printk("... %pSR\n", (void *)addr); Update documentation too.

Convert /proc/timer_list to a proper seq_file with its own iterator. - Cleanups and refactorings of the core timekeeping code by John Stultz. - International Atomic Clock time is managed by the NTP code internally currently but not exposed externally. Separate the TAI code out and add CLOCK_TAI support and TAI support to the hrtimer and posix-timer code, by John Stultz. - Add deep idle support enhacement to the broadcast clockevents core timer code, by Daniel Lezcano: add an opt-in CLOCK_EVT_FEAT_DYNIRQ clockevents feature (which will be utilized by future clockevents driver updates), which allows the use of IRQ affinities to avoid spurious wakeups of idle CPUs - the right CPU with an expiring timer will be woken. - Add new ARM bcm281xx clocksource driver, by Christian Daudt - ... various other fixes and cleanups" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (52 commits) clockevents: Set dummy handler on CPU_DEAD shutdown timekeeping: Update tk->cycle_last in resume posix-timers: Remove unused variable clockevents: Switch into oneshot mode even if broadcast registered late timer_list: Convert timer list to be a proper seq_file timer_list: Split timer_list_show_tickdevices posix-timers: Show sigevent info in proc file posix-timers: Introduce /proc/PID/timers file posix timers: Allocate timer id per process (v2) timekeeping: Make sure to notify hrtimers when TAI offset changes hrtimer: Fix ktime_add_ns() overflow on 32bit architectures hrtimer: Add expiry time overflow check in hrtimer_interrupt timekeeping: Shorten seq_count region timekeeping: Implement a shadow timekeeper timekeeping: Delay update of clock->cycle_last timekeeping: Store cycle_last value in timekeeper struct as well ntp: Remove ntp_lock, using the timekeeping locks to protect ntp state timekeeping: Simplify tai updating from do_adjtimex timekeeping: Hold timekeepering locks in do_adjtimex and hardpps timekeeping: Move ADJ_SETOFFSET to top level do_adjtimex() ...

2013-04-30HID: protect hid_debug_listJiri Kosina
Accesses to hid_device->hid_debug_list are not serialized properly, which could result in SMP concurrency issues when HID debugfs events are accessesed by multiple userspace processess. Serialize all the list operations by a mutex. Spotted by Al Viro. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

No semantic changes, but hid_dump_report should be in hid-debug.c, not in hid-core.c Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-04-30MD: ignore discard request for hard disks of hybid raid1/raid10 arrayShaohua Li
In SSD/hard disk hybid storage, discard request should be ignored for hard disk. We used to be doing this way, but the unplug path forgets it. This is suitable for stable tree since v3.6.

2013-04-30md: bad block list should default to disabled.NeilBrown
Maintenance of a bad-block-list currently defaults to 'enabled' and is then disabled when it cannot be supported. This is backwards and causes problem for dm-raid which didn't know to disable it. So fix the defaults, and only enabled for v1.x metadata which explicitly has bad blocks enabled. The problem with dm-raid has been present since badblock support was added in v3.1, so this patch is suitable for any -stable from 3.1 onwards.
