powerpc/83xx: Make serial ports work on MPC8315E-RDB w/ FSL U-Boots

FSL U-Boots use /soc8315@e0000000 node to search and fixup serial
nodes' clock-frequency properties. Though in upstream kernels we use
new naming convention -- for IMMR address space dts files specify
/immr@e0000000 nodes.

This makes FSL U-Boots fail to fixup the clock frequencies, and that
leads to serial ports misbehaviour. We can workaround the issue by
filling the clock frequency values manually.

p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for
ethernet nodes, so users should either change the .dts file locally
or set MAC address via `ifconfig hw ether' command.

powerpc/powermac: Fix occasional SMP boot failure

The PowerMac kernel occasionally fails to bring up the secondary CPUs on
SMP, the trigger factor seem to be fairly random and related to location
of code and data.

This appears to be due to the initial loading of the TOC value by the
secondary processor which now happens before we clear HID4:RM_CI (Real
Mode Cache Invalidate). This bit should really be cleared before we do
any load or store other than fetching code.

This fix works based on the assumption that all SMP 64-bit PowerMacs use
variants of the 970, which fortunately is true, by explicitely clearing
that bit, adding an slbia for good measure as RM_CI mode is known to
create bogus ERAT entries.

Apart from sleep_on() calls that could be easily converted to

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

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.

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: Alchemy: Fix up PM code on Au1550/Au1200

Au1550/Au1200 have a different memory controller which requires additi-
onal code to properly put memory to sleep (code taken from AMD/RMI's
Linux-2.6.11 source package).

Also fix up the remaining pm-related paths to compile on Au1200/Au1550
platforms.

MIPS: Alchemy: move calc_clock function.

Now that nothing in time.c depends on calc_clock, it can
be moved to clocks.c where it belongs.
While at it, give it a better non-generic name and call it
as soon as possible in plat_mem_init.

MIPS: Alchemy: RTC counter clocksource / clockevent support.

Add support for the 32 kHz counter1 (RTC) as clocksource / clockevent
device.  As a nice side effect, this also enables use of the 'wait'
instruction for runtime idle power savings.

If the counters aren't enabled/working properly, fall back on the
cp0 counter clock code.

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.

MIPS: Alchemy: remove cpu_table.

Remove the cpu_table:
- move detection of whether c0_config[OD] is read-only and should be set
  to fix various chip errata to au1000 headers.
- move detection of write-only sys_cpupll to au1000 headers.
- remove the BCLK switching code:  Activation of this features should be
  left to the boards using the chips since it also affects external devices
  tied to BCLK, and only the board designers know whether it is safe to
  enable.
