[PATCH v7 0/8] sched/fair: Get rid of sched_domains_curr_level hack for tl->cpumask()

[K Prateek Nayak]

This version uses Peter's suggestion from [1] as if and incrementally
adds cleanup on top to the arch/ bits. I've tested the x86 side but the
PowerPC and the s390 bits are only build tested. Review and feedback is
greatly appreciated.

Patches are prepared on top of tip:master at commit 4628e5bbca91 ("Merge
branch into tip/master: 'x86/tdx'")
---
changelog v6..v7:

o Fix the s390 and ppc build errors (Intel test robot)

o Use Peter's diff as is and incrementally do the cleanup on top. The
  PowerPC part was slightly more extensive due to the lack of
  CONFIG_SCHED_MC in arch/powerpc/Kconfig.

v6: https://lore.kernel.org/lkml/20250825120244.11093-1-kprateek.nayak@amd.com/
