[PATCH 1/1] x86/platform/hyperv: When on Hyper-v use NULL legacy PIC

2014-04-03 Thread K. Y. Srinivasan
Use the NULL legacy PIC when on Hyper-V. With this change we can support kexec even when booting on EFI firmware. This patch has been tested on both EFI as well as non-EFI firmware stacks on Hyper-V. This patch is required to support kexec on EFI firmware on Hyper-V. Please apply. Signed-off-by:
