depending on the boot mode, and these should override the defaults in
the builtin cmdline.
The default MIPS_CMDLINE_FROM_BOOTLOADER option prepends the
bootloader's cmdline to the builtin cmdline so is not suitable for this

MIPS KVM uses different ASIDs for guest execution than for the host.
The host ASID is saved on the stack when entering the guest with
__kvm_mips_vcpu_run(), and restored again before returning back to the
caller (exit to userland).
- This does not take into account that pre-emption may have taken place
during that time, which may have started a new ASID cycle and resulted
in that process' ASID being invalidated and reused.
- This does not take into account that the process may have migrated to
a different CPU during that time, with a different ASID assignment
since they are managed per-CPU.
- It is actually redundant, since the host ASID will be restored
correctly by kvm_arch_vcpu_put(), which is called almost immediately
after kvm_arch_vcpu_ioctl_run() returns.
Therefore drop this code from locore.S

Release 6 of the MIPS architecture introduced the bitswap instruction,
which reverses the bits within each byte of a word. Make use of this
instruction to implement the __arch_bitrev* functions, which should be
faster for most MIPSr6 CPUs, reduces code size slightly and allows us to
avoid the lookup table used by the generic implementation, saving 256
bytes in the kernel binary by dropping that.

New Loongson 3 CPU (since Loongson-3A R2, as opposed to Loongson-3A R1,
Loongson-3B R1 and Loongson-3B R2) has many enhancements, such as FTLB,
L1-VCache, EI/DI/Wait/Prefetch instruction, DSP/DSPv2 ASE, User Local
register, Read-Inhibit/Execute-Inhibit, SFB (Store Fill Buffer), Fast
TLB refill support, etc.
This patch introduce a config option, CONFIG_LOONGSON3_ENHANCEMENT, to
enable those enhancements which are not probed at run time. If you want
a generic kernel to run on all Loongson 3 machines, please say 'N'
here. If you want a high-performance kernel to run on new Loongson 3
machines only, please say 'Y' here.
Some additional explanations:
1) SFB locates between core and L1 cache, it causes memory access out
of order, so writel/outl (and other similar functions) need a I/O
reorder barrier.
2) Loongson 3 has a bug that di instruction can not save the irqflag,
so arch_local_irq_save() is modified. Since CPU_MIPSR2 is selected
by CONFIG_LOONGSON3_ENHANCEMENT, generic kernel doesn't use ei/di
at all.
3) CPU_HAS_PREFETCH is selected by CONFIG_LOONGSON3_ENHANCEMENT, so
MIPS_CPU_PREFETCH (used by uasm) probing is also put in this patch.

Loongson-3 maintains cache coherency by hardware, this means:
1) It's icache is coherent with dcache.
2) It's dcaches don't alias (maybe depend on PAGE_SIZE).
3) It maintains cache coherency across cores (and for DMA).
So we can skip most cache flush operations by setting relevant handlers
to `cache_noop' in `r4k_cache_init'.

Propagate sNaN payload in quieting in the legacy-NaN mode as well. If
clearing the quiet bit would produce infinity, then set the next lower
trailing significand field bit, matching the SB-1 and BMIPS5000 hardware
implementations. Some other MIPS FPU hardware implementations do
produce the default qNaN bit pattern instead.
This reverts some changes made for semantics preservation with commit
dc3ddf42 [MIPS: math-emu: Update sNaN quieting handlers], consequently
bringing back most of the semantics from before commit fdffbafb [Lots of
FPU bug fixes from Kjeld Borch Egevang.], except from the qNaN produced
in the infinity case. Previously the default qNaN bit pattern was
produced in that case.

Since commit 8cb48fe169 ("MIPS: Provide correct siginfo_t.si_stime"),
MIPS' uapi/asm/siginfo.h has included uapi/asm-generic/siginfo.h
directly before defining MIPS' struct siginfo, in order to get the
necessary definitions needed for the siginfo struct without the generic
copy_siginfo() hitting compiler errors due to struct siginfo not yet
being defined.
Now that the generic copy_siginfo() is moved out to linux/signal.h we
can safely include asm-generic/siginfo.h before defining the MIPS
specific struct siginfo, which avoids the uapi/ include as well as
breakage due to generic copy_siginfo() being defined before struct
siginfo.
