Subject: Use fixed-width types in the memory event interface
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~11863
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=cecde1f9670adb95274c56e126d62d8a6d86f8cf;p=xen.git

Use fixed-width types in the memory event interface

Set the types in the public memory_event header file to use
fixed-sized and self-aligned fields rather than "unsigned long".  AIUI
this feature only works with 64-bit hypervisors but I think this
change will be necessary to use 32-on-64 dom0 tools.

This breaks compatibility with older builds of the tools, but I can't
see any way to avoid it short of __attribute__((__packed__)).
