[Qemu-devel] [PATCH v2 05/10] kvm: Set sigmask length to 16 for MIPS targets

[James Hogan]

From: Sanjay Lal <address@hidden>

MIPS/Linux is unusual in having 128 signals rather than just 64 like
most other architectures. This means its sigmask is 16 bytes instead of
8, so correct kvm_set_signal_mask to pass the correct sigmask->len to
KVM_SET_SIGNAL_MASK.
