Commit 8792468da5e1 "powerpc: Add the ability to save FPU without giving it up" unexpectedly removed the MSR_FE0 and MSR_FE1 bits from the bitmask used to update the MSR of the previous thread in __giveup_fpu() causing a KVM-PR MacOS guest to lockup and panic the kernel. Reinstate these bits to the MSR bitmask to enable MacOS guests to run under 32-bit KVM-PR once again without issue. Signed-off-by: Mark Cave-Ayland <redacted>
Applied to powerpc next, thanks. https://git.kernel.org/powerpc/c/fe1ef6bcdb4fca33434256a802a3ed6a cheers
