SMSM is not symmetrical, the incoming bits from WCNSS are available at index 6, but the outgoing host id for WCNSS is 3. Further more, upstream references the base of APCS (in contrast to downstream), so the register offset of 8 must be included.

When running as Xen pv guest %gs is initialized some time after C code is started. Depending on stack protector usage this might be too late, resulting in page faults. So setup %gs and MSR_GS_BASE in assembly code already.

Patch "x86/kexec: Make kexec (mostly) work in 5-level paging mode" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled x86/kexec: Make kexec (mostly) work in 5-level paging mode to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: x86-kexec-make-kexec-mostly-work-in-5-level-paging-mode.patch and it can be found in the queue-4.14 subdirectory.

Shutemov" <kirill.shutemov(a)linux.intel.com> Date: Mon, 29 Jan 2018 14:08:45 +0300 Subject: x86/kexec: Make kexec (mostly) work in 5-level paging mode From: Kirill A. Shutemov <kirill.shutemov(a)linux.intel.com> commit 5bf30316991d5bcda046343ee77d823cf16fdd03 upstream. Currently kexec() will crash when switching into a 5-level paging enabled kernel. I missed that we need to change relocate_kernel() to set CR4.LA57 flag if the kernel has 5-level paging enabled. I avoided using #ifdef CONFIG_X86_5LEVEL here and inferred if we need to enable 5-level paging from previous CR4 value. This way the code is ready for boot-time switching between paging modes. With this patch applied, in addition to kexec 4-to-4 which always worked, we can kexec 4-to-5 and 5-to-5 - while 5-to-4 will need more work.
