x86/mtrr: Revert 90b926e68f50 ("x86/pat: Fix pat_x_mtrr_type() for MTRR disabled case")
commit f9f57da2c2d119dbf109e3f6e1ceab7659294046 upstream
The requested patch fixes ioremap for certain devices when running as a Xen Dom0. Without the patch, one example is TPM device probing failing with: tpm_tis IFX:00: ioremap failed for resource
The requested patch did not include a Fixes tag, but it was intended as a fix to upstream 90b926e68f500844dff16b5bcea178dc55cf580a, which was subsequently backported to 6.1 as c1c59538337ab6d45700cb4a1c9725e67f59bc6e. The requested patch being a fix can be seen in the thread here: https://lore.kernel.org/lkml/167636735608.4906.4788207020350311572.tip-bot2@...
I think it's only applicable to 6.1
Thanks, Jason
