  RISC-V: K210 defconfigs: Drop redundant MEMBARRIER=n (2022-03-31 17:19:27 -0700)

----------------------------------------------------------------
RISC-V Patches for the 5.18 Merge Window, Part 2

This has a handful of new features

* Support for CURRENT_STACK_POINTER, which enables some extra stack
  debugging for HARDENED_USERCOPY.
* Support for the new SBI CPU idle extension, via cpuidle and suspend
  drivers.
* Profiling has been enabled in the defconfigs.

but is mostly fixes and cleanups.

----------------------------------------------------------------
There are no merge conflicts.  I'm getting on allyesconfig warning in
drivers/misc/habanalabs, but that appears to just be a 32-bit problem (it's
happening on 32-bit x86 as well).  I've sent a patch for that, but I doubt it's
a RISC-V issue so I'm sending this at the same time.

With that patch I get clean build that boot after my test merge.
