Merge tag 'mips_fixes_5.2_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

2019-07-06T17:32:12+00:00

Pull MIPS fixes from Paul Burton:
 "A few more MIPS fixes:

   - Fix a silly typo in virt_addr_valid which led to completely bogus
     behavior (that happened to stop tripping up hardened usercopy
     despite being broken).

   - Fix UART parity setup on AR933x systems.

   - A build fix for non-Linux build machines.

   - Have the 'all' make target build DTBs, primarily to fit in with the
     behavior of scripts/package/builddeb.

   - Handle an execution hazard in TLB exceptions that use KScratch
     registers, which could inadvertently clobber the $1 register on
     some generally higher-end out-of-order CPUs.

   - A MAINTAINERS update to fix the path to the NAND driver for Ingenic
     systems"

MIPS: Add missing EHB in mtc0 -> mfc0 sequence.

2019-06-24T20:43:12+00:00

Add a missing EHB (Execution Hazard Barrier) in mtc0 -> mfc0 sequence.
Without this execution hazard barrier it's possible for the value read
back from the KScratch register to be the value from before the mtc0.

Reproducible on P5600 & P6600.

The hazard is documented in the MIPS Architecture Reference Manual Vol.
III: MIPS32/microMIPS32 Privileged Resource Architecture (MD00088), rev
6.03 table 8.1 which includes:

   Producer | Consumer | Hazard
  ----------|----------|----------------------------
   mtc0     | mfc0     | any coprocessor 0 register

MIPS: have "plain" make calls build dtbs for selected platforms

2019-06-20T21:52:56+00:00

scripts/package/builddeb calls "make dtbs_install" after executing
a plain make (i.e. no build targets specified). It will fail if dtbs
were not built beforehand. Match the arm64 architecture where DTBs get
built by the "all" target.

MIPS: fix build on non-linux hosts

2019-06-19T22:55:53+00:00

calc_vmlinuz_load_addr.c requires SZ_64K to be defined for alignment
purposes.  It included "../../../../include/linux/sizes.h" to define
that size, however "sizes.h" tries to include  which
assumes linux system headers.  These may not exist eg. the following
error was encountered when building Linux for OpenWrt under macOS:

In file included from arch/mips/boot/compressed/calc_vmlinuz_load_addr.c:16:
arch/mips/boot/compressed/../../../../include/linux/sizes.h:11:10: fatal error: 'linux/const.h' file not found
         ^~~~~~~~~~

Change makefile to force building on local linux headers instead of
system headers.  Also change eye-watering relative reference in include
file spec.

Thanks to Jo-Philip Wich & Petr Štetiar for assistance in tracking this
down & fixing.

MIPS: ath79: fix ar933x uart parity mode

2019-06-19T20:39:49+00:00

While trying to get the uart with parity working I found setting even
parity enabled odd parity insted. Fix the register settings to match
the datasheet of AR9331.

A similar patch was created by 8devices, but not sent upstream.
