2012-02-03mfd: Avoid twl6040-codec PLL reconfiguration when not neededPeter Ujfalusi
Do not reconfigure the PLL in case it has been configured already with the requested parameters. In case of different PLL configuration do only the needed changes. This can save considerable amount of time since we can avoid the defined protocol (with delays) for the PLL configuration.

2012-02-03ARM: 7314/1: kuser: consistently use usr_ret for returning from helpersWill Deacon
__kuser_cmpxchg64 has a return path using bx lr to get back to the caller. This is actually ok since the code in question is predicated on CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret macro is probably better.

2012-02-03ARM: at91: implement the standby function for pm/cpuidleDaniel Lezcano
This patch groups the self-refresh on/cpu_do_idle/self-refresh off into a single 'standby' function. The standby routine for rm9200 has been turned into an asm routine to have a better control of the self refresh and to prevent a memory access when running this code. Draining the write buffer is done automatically when switching for the self refresh on sam9, so the instruction is added to the rm9200 only.

2012-02-03ARM: at91: remove wait_for_interrupt definitionDaniel Lezcano
All the "wait_for_interrupt" definition are aliases to cpu_do_idle. Only the rm9200 has an asm routine to switch to wfi. But the cpu_do_idle for this platform has exactly the same asm routine. arch/arm/mm/proc-arm920.S .. ENTRY(cpu_arm920_do_idle) mcr p15, 0, r0, c7, c0, 4 @ Wait for interrupt .. Then it is safe to invoke cpu_do_idle for this platform. As all the wait_for_interrupts are definition for cpu_do_idle, let's remove it and replace its invokation by cpu_do_idle.

2012-02-03ixgbevf: Fix mailbox interrupt ack bugGreg Rose
Remove jump to out label that was skipping over code to replace the ack bit in the mailbox cache variable. This was causing driver mailbox routines that poll for the PF to ack a message to time out which would in turn cause all other mailbox messages to fail. Also replace the mailbox cache variable message indication bit when a message is found so that other functions that choose to poll for a mailbox message from the PF won't miss it.

2012-02-03perf: Remove deprecated WARN_ON_ONCE()Stephane Eranian
With the new throttling/unthrottling code introduced with commit: e050e3f0a71b ("perf: Fix broken interrupt rate throttling") we occasionally hit two WARN_ON_ONCE() checks in: - intel_pmu_pebs_enable() - intel_pmu_lbr_enable() - x86_pmu_start() The assertions are no longer problematic. There is a valid path where they can trigger but it is harmless. The assertion can be triggered with: $ perf record -e instructions:pp .... Leading to paths: intel_pmu_pebs_enable intel_pmu_enable_event x86_perf_event_set_period x86_pmu_start perf_adjust_freq_unthr_context perf_event_task_tick scheduler_tick And: intel_pmu_lbr_enable intel_pmu_enable_event x86_perf_event_set_period x86_pmu_start perf_adjust_freq_unthr_context. perf_event_task_tick scheduler_tick cpuc->enabled is always on because when we get to perf_adjust_freq_unthr_context() the PMU is not totally disabled. Furthermore when we need to adjust a period, we only stop the event we need to change and not the entire PMU. Thus, when we re-enable, cpuc->enabled is already set. Note that when we stop the event, both pebs and lbr are stopped if necessary (and possible).

2012-02-02drivers/tty/vt/vt_ioctl.c: fix KDFONTOP 32bit compatibility layerSamuel Thibault
KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland with a 64bit kernel if the font width is not 8. This is because the compatibility layer introduced by e9216651 ("tty: handle VT specific compat ioctls in vt driver") forces the addition of the KD_FONT_FLAG_OLD flag, which makes con_font_get return EIO in such case. This flag should *not* be set for KDFONTOP, since it's actually the whole point of this flag (see comment in con_font_set for instance).

Root cause: for x86_64, 2048g (with 2g hole at [2g,4g), and TOP2 will be 2050g), will have 16400 memory block. find_memory_block/subsys_find_device_by_id will be expensive with that many entries. Actually, we don't need to find that memory block for BOOT path. Skip that finding make it get back to normal.

Change the way channels objects are linked together by peak_pci_probe() avoiding any kernel oops when driver is removed. Side effect is that the list is now browsed from last to first channel.
