      MIPS: Fix potencial corruption · a16dad77
      由 Ralf Baechle 提交于 
      Normally r4k_dma_cache_inv should only ever be called with cacheline
aligned addresses.  If however, it isn't there is the theoretical
possibility of data corruption.  There is no correct way of handling this
and anyway, it should only happen if the DMA API is used incorrectly
so drop

There is a different corruption scenario with these CACHE instructions
removed but again there is no way of handling this correctly and it can
be triggered only through incorrect use of the DMA API.

So just get rid of the complexity.

      MIPS: Fix for warning from FPU emulation code · 51d943f0
      由 Ralf Baechle 提交于 
      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.  da0bac33
(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.

      MIPS: Handle COP3 Unusable exception as COP1X for FP emulation · 051ff44a
      由 Maciej W. Rozycki 提交于 
       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.
