Subject: [GIT PULL] x86/mm changes for v5.5

Linus,

Please pull the latest x86-mm-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-mm-for-linus

   # HEAD: 7f264dab5b60343358e788d4c939c166c22ea4a2 x86/mm/pat: Rename pat_rbtree.c to pat_interval.c

The main changes in this cycle were:

 - A PAT series from Davidlohr Bueso, which simplifies the memtype rbtree 
   by using the interval tree helpers. (There's more cleanups in this 
   area queued up, but they didn't make the merge window.)

 - Also flip over CONFIG_X86_5LEVEL to default-y. This might draw in a 
   few more testers, as all the major distros are going to have 5-level 
   paging enabled by default in their next iterations.

 - Misc cleanups.


 Thanks,

	Ingo
