The patch titled
lguest: fix TSC "divide error: 0000 [#1]" boot crash
has been removed from the -mm tree. Its filename was
lguest-the-guest-code-lguest-fix-tsc-divide-error-0000-boot-crash.patch
This patch was dropped because it was folded into lguest-the-guest-code.patch
------------------------------------------------------
Subject: lguest: fix TSC "divide error: 0000 [#1]" boot crash
From: Rusty Russell <rusty@xxxxxxxxxxxxxxx>
Configuring a guest with < CONFIG_M586TSC reveals an lguest bug: the TSC
code expects to see the TSC capability bit, but we weren't setting up the
capabilities until much later in check_bugs -> identify_boot_cpu ->
identify_boot_cpu.
Do the same thing as Xen and the head.S native code: populate the first
capability word before start_kernel().
