openrisc: uaccess: Add user address space check to access_ok (2020-08-09 07:57:21 +0900)

----------------------------------------------------------------
OpenRISC updates for 5.9

A few patches all over the place during this cycle, mostly bug and
sparse warning fixes for OpenRISC, but a few enhancements too. Note,
there are 2 non OpenRISC specific fixups.

Non OpenRISC fixes:

- In init we need to align the init_task correctly to fix an issue with
MUTEX_FLAGS, reviewed by Peter Z. No one picked this up so I kept it
on my tree.
- In asm-generic/io.h I fixed up some sparse warnings, OK'd by Arnd.
Arnd asked to merge it via my tree.

OpenRISC fixes:

- Many fixes for OpenRISC sprase warnings.
- Add support OpenRISC SMP tlb flushing rather than always flushing the
entire TLB on every CPU.
- Fix bug when dumping stack via /proc/xxx/stack of user threads.
