[Qemu-devel] [PATCH qemu v10 01/14] linux-headers: Update to 4.2-rc1

[Alexey Kardashevskiy <aik@ozlabs.ru>]

This updates linux-headers against master 4.2-rc1 (commit
d770e558e21961ad6cfdf0ff7df0eb5d7d4f0754). This is the result of
./scripts/update-linux-headers.sh work.

Cc: Paolo Bonzini <pbonzini@redhat.com>
