The default implementation of 'cpu_has_fpu' macro calls
smp_processor_id() which causes this warning to be printed when
preemption is enabled:
[ 4.664000] Algorithmics/MIPS FPU Emulator v1.5
[ 4.676000] BUG: using smp_processor_id() in preemptible [00000000] code: ini
[ 4.700000] caller is fpu_emulator_cop1Handler+0x434/0x27b8
This problem got introduced in November 2009 by
af1d2af877ef6c36990671bc86a5b9c5bb50b1da (lmo) [MIPS: Fix emulation of
64-bit FPU on 64-bit CPUs.] rsp. da0bac3341
(kernel.org) [MIPS: Fix emulation of 64-bit FPU on FPU-less 64-bit CPUs.]
in 2.6.32.
Fixed by rewriting cop1_64bit() to return a constant whenever possible
but most importantly avoid the use pf cpu_has_fpu entirely.

Patchwork: https://patchwork.linux-mips.org/patch/4225/
Our FP emulator is hardcoded for the MIPS IV FP instruction set and does
not match the FP ISA with the general ISA. However for the few MIPS IV FP
instructions that use the COP1X major opcode it relies on the Coprocessor
Unusable exception to be delivered as a COP1 rather than COP3 exception.
This includes indexed transfer (LDXC1, etc.) and FP multiply-accumulate
(MADD.D, etc.) instructions.
All the MIPS I, II, III and IV processors and some newer chips that do not
implement the FPU use the COP3 exception however. Therefore I believe the
kernel should follow and redirect any COP3 Unusable traps to the emulator
unless an actual FPU part or core is present.
This is a change that implements it. Any minor opcode encodings that are
not recognised as valid FP instructions are rejected by the emulator and
will result in a SIGILL signal being delivered as they currently do. We
do not support vendor-specific coprocessor 3 implementations supported
with MIPS I and MIPS II ISA processors; we never set CP0.Status.CU3.
[Ralf: On MIPS IV processors the kernel always enables the XX bit which
replaces the CU3 bit off earlier architecture revisions.]
If matching between the CPU and the FPU ISA is considered required one
day, this can still be done in the emulator itself. I think the CpU
exception dispatcher is not the right place to do this anyway, as there
are further differences between MIPS I, MIPS II, MIPS III, MIPS IV and
MIPS32 FP ISAs.
Corresponding explanation of this implementation is included within the
change itself.

When poweroff machine, kernel_power_off() call disable_nonboot_cpus().
And if we have HOTPLUG_CPU configured, disable_nonboot_cpus() is not an
empty function but attempt to actually disable the nonboot cpus. Since
system state is SYSTEM_POWER_OFF, play_dead() won't be called and thus
disable_nonboot_cpus() hangs. Therefore, we make this patch to avoid
poweroff failure.

o Second level cache - ECC protected, provides SECDED.
o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will
will only initialize if ECC is enabled on a system so is safe to run on

Pull MIPS fixes from Ralf Baechle:
"Three issues fixed accross the field:
- Some functions that were recently outlined as part of a preemption
fix were causing problems with function tracing.
- The recently merged in-kernel MPI library uses very outdated
headers that contain MIPS-specific code which won't build on with
gcc 4.4 or newer.
- The MIPS non-NUMA memory initialization was making only a very
half-baked attempt at merging adjacent memory ranges. This kept
the code simple enough but is now causing issues with kexec."

MPI: Fix compilation on MIPS with GCC 4.4 and newer
MIPS: Fix crash that occurs when function tracing is enabled
MIPS: Merge overlapping bootmem ranges
While the EEH does recovery on the specific PE that has PCI errors,
the PCI devices belonging to the PE will be removed and the PE will
be marked as invalid since we still need the information stored in
the PE. We only invalidate the PE when it doesn't have associated
EEH devices and valid child PEs. However, the code used to check
that is wrong. The patch fixes that.

of/address: sparc: Declare of_iomap as an extern function for sparc again
This bug-fix makes sure that of_iomap is defined extern for sparc so that the
sparc-specific implementation of_iomap is once again used when including
include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
sparc relies on this.
The bug was inadvertently introduced in a850a75, "of/address: add empty static
inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
!CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.

Merge tag 'parisc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/parisc-2.6
Pull PARISC fixes from James Bottomley:
"This is two bug fixes: one fixes a loophole where rt_sigprocmask()
with the wrong values panics the box (Denial of Service) and the other
fixes an aliasing problem with get_shared_area() which could cause
data corruption.

In other words, rt_sigprocmask(69, (void *)69, 69) done by 32bit process
will promptly panic the box.

Merge tag 'omap-for-v3.7-rc5/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
Few more regression fixes related to u-boot only muxing
essential pins.
* tag 'omap-for-v3.7-rc5/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP4: TWL: mux sys_drm_msecure as output for PMIC
ARM: OMAP3: igep0020: Set WIFI/BT GPIO pins in correct mux mode
ARM: OMAP: Add maintainer entry for IGEP machines
Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:
gpio_request_one()
gpio_set_debounce()
gpio_free()
It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.
Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.
While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.
Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.
