Don't disable bottom half while the crypto engine is in use, as it
should be unnecessary: All kernel crypto engine usage is wrapped with
crypto engine state save/restore, so if we get interrupted by softirq
that uses crypto they should save and restore our context.
This actually fixes an issue when running OCTEON MD5 with interrupts
disabled (tcrypt mode=302). There's a WARNING because the module is
trying to enable the bottom half with irqs disabled:

The IRQF_DISABLED flag is a NOOP and has been scheduled for removal
since Linux v2.6.36 by commit 6932bf37bed4 ("genirq: Remove
IRQF_DISABLED from core code").
According to commit e58aa3d2d0cc ("genirq: Run irq handlers with
interrupts disabled"), running IRQ handlers with interrupts
enabled can cause stack overflows when the interrupt line of the
issuing device is still active.
This patch ends the grace period for IRQF_DISABLED (i.e.,
SA_INTERRUPT in older versions of Linux) and removes the
definition and all remaining usages of this flag.
There's still a few non-functional references left in the kernel
source:
- The bigger hunk in Documentation/scsi/ncr53c8xx.txt is removed entirely
as IRQF_DISABLED is gone now; the usage in older kernel versions
(including the old SA_INTERRUPT flag) should be discouraged. The
trouble of using IRQF_SHARED is a general problem and not specific to
any driver.
- I left the reference in Documentation/PCI/MSI-HOWTO.txt untouched since
it has already been removed in linux-next.
- All remaining references are changelogs that I suggest to keep.

Currently the guest exit trace event saves the VCPU pointer to the
structure, and the guest PC is retrieved by dereferencing it when the
event is printed rather than directly from the trace record. This isn't
safe as the printing may occur long afterwards, after the PC has changed
and potentially after the VCPU has been freed. Usually this results in
the same (wrong) PC being printed for multiple trace events. It also
isn't portable as userland has no way to access the VCPU data structure
when interpreting the trace record itself.
Lets save the actual PC in the structure so that the correct value is
accessible later.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS:
- a number of fixes that didn't make the 3.19 release.
- a number of cleanups.
- preliminary support for Cavium's Octeon 3 SOCs which feature up to
48 MIPS64 R3 cores with FPU and hardware virtualization.
- support for MIPS R6 processors.
Revision 6 of the MIPS architecture is a major revision of the MIPS
architecture which does away with many of original sins of the
architecture such as branch delay slots. This and other changes in
R6 require major changes throughout the entire MIPS core
architecture code and make up for the lion share of this pull
request.
- finally some preparatory work for eXtendend Physical Address
support, which allows support of up to 40 bit of physical address
space on 32 bit processors"
[ Ahh, MIPS can't leave the PAE brain damage alone. It's like
every CPU architect has to make that mistake, but pee in the snow
by changing the TLA. But whether it's called PAE, LPAE or XPA,
it's horrid crud - Linus ]

Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

In commit c441d4a54c6e ("MIPS: mm: Only build one microassembler that
is suitable"), the Makefile at arch/mips/mm was rewritten to only
build the "right" microassembler file, depending on whether
CONFIG_CPU_MICROMIPS is set or not.
In the files, however, there are still preprocessor definitions
depending on CONFIG_CPU_MICROMIPS. The #ifdef around them can now
never evaluate to true, so let's remove them altogether.
This inconsistency was found using the undertaker-checkpatch tool.

The current code uses bits 0-6 of the sys_cpupll register to calculate
core clock speed. However this is only valid on Au1300, on all earlier
models the hardware only uses bits 0-5 to generate core clock.
This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll
is set as well, which ultimately lead the code to calculate a bogus cpu
core clock and also uart base clock down the line.

Pull kconfig updates from Michal Marek:
"Yann E Morin was supposed to take over kconfig maintainership, but
this hasn't happened. So I'm sending a few kconfig patches that I
collected:
- Fix for missing va_end in kconfig
- merge_config.sh displays used if given too few arguments
- s/boolean/bool/ in Kconfig files for consistency, with the plan to
only support bool in the future"
* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kconfig: use va_end to match corresponding va_start
merge_config.sh: Display usage if given too few arguments
kconfig: use bool instead of boolean for type definition attributes

Export the _save_msa asm function used by the lose_fpu(1) macro to GPL
modules so that KVM can make use of it when it is built as a module.
This fixes the following build error when CONFIG_KVM=m and
CONFIG_CPU_HAS_MSA=y due to commit f798217dfd03 ("KVM: MIPS: Don't leak
FPU/DSP to guest"):
ERROR: "_save_msa" [arch/mips/kvm/kvm.ko] undefined!

This function was renamed to mips_cpu_irq_of_init(), so fix it to avoid
a compile error.

Provide correct siginfo_t.si_stime on MIPS64
Bug description:
MIPS version of copy_siginfo() is not aware of alignment on platforms with
64-bit long integers, which leads to an incorrect si_stime passed to signal
handlers, because the last element (si_stime) of _sifields._sigchld is not
copied. If _MIPS_SZLONG is 64, then the _sifields starts at the offset of
4 * sizeof(int).
Patch description:
Use the generic copy_siginfo, which doesn't have this problem.

We need to check the ASEs support against the core's CFLAGS instead
of depending to the default -march option from the toolchain.

The loongson 3A cores do not select a suitable -march option so the build
system uses the default one from the toolchain. This may or may not be
suitable for a loongson 3A build. In order to avoid that, we explicitly set
a suitable -march option for that core. Furthermore, some very old
compilers don't support -march= at all and there is the possibility of
toolchain combinations such as GCC 4.9 and binutils 2.24 for which
-march=loongson3a will result in MIPS64 R2 code being generated but then
rejected by GAS. So treat the Longsoon 3A as an R2 CPU.
