[Qemu-devel] [PULL v2 02/10] mips/kvm: Disable FPU on reset with KVM

[Paolo Bonzini]

From: James Hogan <james.hogan@imgtec.com>

KVM doesn't yet support the MIPS FPU, or writing to the guest's Config1
register which contains the FPU implemented bit. Clear QEMU's version of
that bit on reset and display a warning that the FPU has been disabled.

The previous incorrect Config1 CP0 register value wasn't being passed to
KVM yet, however we should ensure it is set correctly now to reduce the
risk of breaking migration/loadvm to a future version of QEMU/Linux that
does support it.

I'm afraid this patch causes the shell to complain when running
configure:

../../configure: 1506: test: unexpected operator

That's the line
  if test "$stack_protector" == "yes" ; then

There is no "==" operator in POSIX sh; you want
a single "=" for string comparison.

thanks
