Merge tag 'x86_mm_for_6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 LAM (Linear Address Masking) support from Dave Hansen:
"Add support for the new Linear Address Masking CPU feature.
This is similar to ARM's Top Byte Ignore and allows userspace to store
metadata in some bits of pointers without masking it out before use"
* tag 'x86_mm_for_6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
