Vlastimil Babka 5f26d76c3f x86/dumpstack: Indicate in Oops whether PTI is configured and enabled ...

CONFIG_PAGE_TABLE_ISOLATION is relatively new and intrusive feature that may
still have some corner cases which could take some time to manifest and be
fixed. It would be useful to have Oops messages indicate whether it was
enabled for building the kernel, and whether it was disabled during boot.

Example of fully enabled:

	Oops: 0001 [#1] SMP PTI

Example of enabled during build, but disabled during boot:

	Oops: 0001 [#1] SMP NOPTI

We can decide to remove this after the feature has been tested in the field
long enough.

[ tglx: Made it use boot_cpu_has() as requested by Borislav ]
