kvm-kmod-2.6.36

Kernel 2.6.36 is baked, and so is the corresponding kvm-kmod now. A few fixes went in since -rc6, see below.

This release also marks the end of life for the kvm-kmod-2.6.35 series - although there are a few unreleased kvm-kmod fixes in git. But the very same patches can be obtained via .36 now, and there is currently no 2.6.35.8 with KVM updates in sight.

KVM changes since kvm-kmod-2.6.36-rc6:
- x86: Fix fs/gs reload oops with invalid ldt
- x86: Move TSC reset out of vmcb_init
- x86: Fix SVM VMCB reset

kvm-kmod changes:
- x86: make sure kvm_get_desc_base() doesn't sign extend
- Improve accuracy of tboot_enabled wrapping

Hello Jan,
trying to compile on 2.6.32.25-rc1 I get:

make -C /usr/src/redhat/BUILD/linux-2.6.32 M=`pwd` \

                        -I`pwd`/include-compat -I`pwd`/x86 \
                        -include  include/linux/autoconf.h \
                        -include `pwd`/x86/external-module-compat.h" \

hmm,
seems to be regression between kvm-kmod-2.6.35-rc3 and kvm-kmod-2.6.35, namely this snippet:

n.

Oops, small but obviously fatal copy&paste mistake. Does this solve your issue?
