[Qemu-devel] [PATCH] update-linux-headers.sh: Don't hard code list of architectures
Tue, 17 Jul 2012 17:41:47 +0100
Rather than hardcoding the list of architectures in the kernel
header update script, just import headers for every architecture
which supports KVM. This reduces the number of QEMU files which
need to be updated to add support for a new KVM architecture.
It also means we won't break if the kernel drops support for
an architecture in the future.

I'd like this for ARM, obviously. NB that this change will mean we'll
pick up the ia64 kvm headers next time somebody does a kernel header
update; this seems harmless (and perhaps even useful?). ia64 'make
headers_install' is a bit noisy as of 3.5-rc5 but succeeds anyway.
