Subject: update-linux-headers: prepare for hyperv.h removal
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=40bf8e9aede0f9105a9e1e4aaf17b20aaa55f9a0;p=qemu.git

update-linux-headers: prepare for hyperv.h removal

All definitions related to Hyper-V emulation are now taken from the QEMU
own header, so the one imported from the kernel is no longer needed.

Unfortunately it's included by kvm_para.h.

So, until this is fixed in the kernel, teach the header harvesting
script to substitute kernel's hyperv.h with a dummy.
