2009-01-12m68k: amiflop - Get rid of sleep_on callsAndreas Bombe
Apart from sleep_on() calls that could be easily converted to wait_event() and completion calls amiflop also used a flag in ms_delay() and ms_isr() as a custom mutex for ms_delay() without a need for explicit unlocking. I converted that to a standard mutex. The replacement for the unconditional sleep_on() in fd_motor_on() is a complete_all() together with a INIT_COMPLETION() before the mod_timer() call. It appears to me that fd_motor_on() might be called concurrently and fd_select() does not guarantee mutual exclusivity in the case the same drive gets selected again.

2009-01-12Revert "cpumask: use work_on_cpu in acpi-cpufreq.c for drv_read and drv_write"Ingo Molnar
This reverts commit 7503bfbae89eba07b46441a5d1594647f6b8ab7d. Dieter Ries reported bootup soft-hangs and bisected it back to this commit, and reverting this commit gave him a working system. The commit introduces work_on_cpu() use into the cpufreq code, but that is subtly problematic from a lock hierarchy POV: the hotplug-cpu lock is an highlevel lock that is taken before lowlevel locks, and in this codepath we are called with the policy lock taken. Dieter did not have lockdep enabled so we dont have a nice stack trace proof for this, but using work_on_cpu() in such a lowlevel place certainly looks wrong, so we revert the patch. work_on_cpu() needs to be reworked to be more generally usable.

2009-01-12x86: avoid theoretical vmalloc fault loopAndi Kleen
Ajith Kumar noticed: I was going through the vmalloc fault handling for x86_64 and am unclear about the following lines in the vmalloc_fault() function. pgd = pgd_offset(current->mm ?: &init_mm, address); pgd_ref = pgd_offset_k(address); Here the intention is to get the pgd corresponding to the current process and sync it up with the pgd in init_mm(obtained from pgd_offset_k). However, for kernel threads current->mm is NULL and hence pgd = pgd_offset(init_mm, address) = pgd_ref which means the fault handler returns without setting the pgd entry in the MM structure in the context of which the kernel thread has faulted. This could lead to never-ending faults and busy looping of kernel threads like pdflush. So, shouldn't the pgd = pgd_offset(current->mm ?: &init_mm, address); be pgd = pgd_offset(current->active_mm ?: &init_mm, address); We can use active_mm unconditionally because it should be always set.

snd-hda-intel driver used schedule_work() fot the delayed DMA pointer updates, but this has several potential problems: - it may block other eventsd works longer - it may deadlock when probing fails and flush_scheduled_work() is called during probe callback (as probe callback itself could be invoked from eventd) This patch adds an own workq for each driver instance to solve these problems.

2009-01-11MIPS: Alchemy: new userspace suspend interface for development boards.Manuel Lauss
Replace the current sysctl-based suspend interface with a new sysfs- based one which also uses the Linux-2.6 suspend model. To configure wakeup sources, a subtree for the demoboards is created under /sys/power/db1x: sys/ `-- power `-- db1x |-- gpio0 |-- gpio1 |-- gpio2 |-- gpio3 |-- gpio4 |-- gpio5 |-- gpio6 |-- gpio7 |-- timer |-- timer_timeout |-- wakemsk `-- wakesrc The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2 bits of the SYS_WAKEMSK (wakeup source enable) register. Writing '1' enables a wakesource, 0 disables it. The 'timer_timeout' node holds the timeout in seconds after which the TOYMATCH2 event should wake the system. The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex), the 'wakemsk' node can be used to get/set the wakeup mask directly. For example, to have the timer wake the system after 10 seconds of sleep, the following must be done in userspace: echo 10 > /sys/power/db1x/timer_timeout echo 1 > /sys/power/db1x/timer echo mem > /sys/power/sleep This patch also removes the homebrew CPU frequency switching code. I don't understand how it could have ever worked reliably; it does not communicate the clock changes to peripheral devices other than uarts.

2009-01-11MIPS: make cp0 counter clocksource/event usable as fallback.Manuel Lauss
The current mips clock build infrastructure lets a system only use either the MIPS cp0 counter or a SoC specific timer as a clocksource / clockevent device. This patch renames the core cp0 counter clocksource / clockevent functions from mips_* to r4k_* and updates the wrappers in asm-mips/time.h to call these renamed functions instead. Chips which can detect whether it is safe to use a chip-specific timer can now fall back on the cp0 counter if necessary and possible (e.g. Alchemy with a follow-on patch).
