Subject: [PATCH 0/4] x86: Merge fpu and simd exception handlers (v2)

This patch series merges the fpu and simd exception handlers into one
function.  The only difference is where the status bits are read from.
This also applies a fix for multiple simd exceptions that was already
done for fpu.

v2:
Changed the cache flush denied handler to simply redirect to general
protection fault.
Squashed patch to remove die_if_kernel() into patch #1.

[PATCH 1/4] x86-32: Rework cache flush denied handler
[PATCH 2/4] x86: Merge simd_math_error() into math_error()
[PATCH 3/4] x86: Merge kernel_math_error() into math_error()
[PATCH 4/4] x86-32: Don't set ignore_fpu_irq in simd exception
