Today I finished bisecting a boot problem on my IBM X346 (with 64-bit P4
Xeons). 4.5.0 worked fine but I saw the spontaneous reboots during early
boot in 4.6-rc4 and bisected it down to the commit below.
The server does not seem to have NX - dmesg has this:
Notice: NX (Execute Disable) protection missing in CPU!
Full dmesg from adjacent commit is below.
320d25b6a05f8b73c23fc21025d2906ecdd2d4fc is the first bad commit
commit 320d25b6a05f8b73c23fc21025d2906ecdd2d4fc

x86/mm/32: Set NX in __supported_pte_mask before enabling paging
There's a short window in which very early mappings can end up
with NX clear because they are created before we've noticed that
we have NX.
It turns out that we detect NX very early, so there's no need to
defer __supported_pte_mask setup.

I reproduced a failure under KVM, which might be your failure.
Digging around now.

This reverts commit 320d25b6a05f8b73c23fc21025d2906ecdd2d4fc.
This change was problematic for a couple of reasons:
1. It missed a some entry points (Xen things and 64-bit native).
2. The entry it changed can be executed more than once. This isn't
really a problem, but it conflated per-cpu state setup and global
state setup.
3. It broke 64-bit non-NX. 64-bit non-NX worked the other way around from
32-bit -- __supported_pte_mask had NX set initially and was *cleared*
in x86_configure_nx. With the patch applied, it never got cleared.
