Subject: [PATCH 0/4] x86: Merge fpu and simd exception handlers (v2)
Date: Sun, 21 Mar 2010 09:00:42 -0400 [thread overview]
Message-ID: <1269176446-2489-1-git-send-email-brgerst@gmail.com> (raw)
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
