m68k: amiflop - Get rid of sleep_on calls
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.

Revert "cpumask: use work_on_cpu in acpi-cpufreq.c for drv_read and drv_write"
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.

x86: avoid theoretical vmalloc fault loop
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.

Added 'double_rq_lock' forward declaration, allowing double_rq_lock
to be used in _double_lock_balance().

MIPS: Alchemy: new userspace suspend interface for development boards.
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.

MIPS: make cp0 counter clocksource/event usable as fallback.
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).
Existing behaviour is not changed in any way.

- move detection of write-only sys_cpupll to au1000 headers.
- remove the BCLK switching code: Activation of this features should be

tied to BCLK, and only the board designers know whether it is safe to

This patch attempts to modernize core Alchemy interrupt handling code.
- add irq_chips for irq controllers instead of irq type,
- add a set_type() hook to change irq trigger type during runtime,
- add a set_wake() hook to control GPIO0..7 based wakeup,
- use linux' IRQF_TRIGGER_ constants instead of homebrew ones,
- enable GENERIC_HARDIRQS_NO__DO_IRQ.
- simplify plat_irq_dispatch
- merge au1xxx_irqmap into irq.c file, the only place where its
contents are referenced.
- board_init_irq() is now mandatory for every board; use it to register
the remaining (gpio-based) interrupt sources; update all boards
accordingly.
