[PATCH] drop "[PATCH] i386 kexec-on-panic: Don't shutdown the apics"
A patch by Eric was merged (f2b36db692b7ff6972320ad9839ae656a3b0ee3e) and later on reverted back (1e4c85f97fe26fbd70da12148b3992c0e00361fd). Along with above patch, another patch was posted and has been merged (3d1675b41b02d64bd1185903ea0d25a8c0bb6dea). That patch was dependent on the above patch and now it should also be reverted.
