From 12275dd4b747f5d87fa36229774d76bca8e63068 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Mon, 19 Dec 2011 09:30:35 -0500 Subject: Revert "xen/pv-on-hvm kexec: add xs_reset_watches to shutdown watches from old kernel" This reverts commit ddacf5ef684a655abe2bb50c4b2a5b72ae0d5e05. As when booting the kernel under Amazon EC2 as an HVM guest it ends up hanging during startup. Reverting this we loose the fix for kexec booting to the crash kernels.
