Shutdown requests are normally hardware dependent. By extending pvpanic to also handle shutdown requests, guests can submit such requests with an easily implementable and cross-platform mechanism.
Signed-off-by: Thomas Weißschuh <tho...@t-8ch.de> --- This patch was split out from my earlier pvpanic-shutdown series [0]. The original series dropped the usage of the linux/pvpanic.h UAPI header. As we decided to keep the linux header [1] this first commit only adds the spec definition. Then a patch to Linux will add the new events to linux/pvpanic.h. After this the rest of the changes to QEMU will be submitted again.
