The fancy mutex_lock fastpath has too many indirections to track the caller hence all contentions are perceived to come from mutex_lock(). Avoid this by explicitly not using the fastpath code (it was disabled already anyway). Signed-off-by:

It is possible for the current->curr_chain_key to become inconsistent with the current index if the chain fails to validate. The end result is that future lock_acquire() operations may inadvertently fail to find a hit in the cache resulting in a new node being added to the graph for every acquire. Signed-off-by:

Both /proc/lockdep and /proc/lock_stat output may loop infinitely. When a read() requests an amount of data smaller than the amount of data that the seq_file's foo_show() outputs, the output starts looping and outputs the "stuck" element's data infinitely. There may be multiple sequential calls to foo_start(), foo_next()/foo_show(), and foo_stop() for a single open with sequential read of the file. The _start() does not have to start with the 0th element and _show() might be called multiple times in a row for the same element for a given open/read of the seq_file. Also header output should not be happening in _start(). All output should be in _show(), which SEQ_START_TOKEN is meant to help. Having output in _start() may also negatively impact seq_file's seq_read() and traverse() accounting. Signed-off-by:

Make sure the mmc_spi driver can build without CONFIG_BLOCK. Issue noted by "Avuton Olrich" <avuton@gmail.com> and randconfig. While that won't be a common configuration, sometimes embedded boards use SDIO to interface WLAN or Bluetooth chips (vs some parallel interface), and don't provide an MMC/SD socket for use with flash memory cards.

The call to napi_disable() in the PCI shutdown handler is problematic, and is aggravated by the new NAPI. Also, make sure watchdog timer doesn't go off. Signed-off-by:

The 64bit SMP bootup is slightly different to the 32bit one. It enables the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E systems have the C1E feature flag only set in the secondary CPU. Due to the early enable of the boot CPU local APIC timer the APIC timer is registered as a fully functional device. When we detect the wreckage during the bringup of the secondary CPU, we need to force the boot CPU into broadcast mode. Check the C1E caused APIC timer disable, when the secondary APIC timer is initialized. If the boot CPU APIC timer was registered as a functional clock event device, then fix this up and utilize the CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already registered boot CPU APIC timer into broadcast mode. Tested by force injecting the failure mode. Signed-off-by:Thomas Gleixner <tglx@linutronix.de>

if your mask is host-endian, you should apply it after le64_to_cpu(); if it's little-endian - before. Doing both (for the same mask and little-endian value) is broken. Signed-off-by:
