Commit 9f471129 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

Pull MIPS fixes from Ralf Baechle:
 "A fair number of build fixes for various configurations.

  Fixes to BPF, and the BCM47xx platform code, a preemption fix for the
  Loongson core, a syscall auditing fix, wire up the new getrandom and
  memfd_create.  Several patches for EVA"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (30 commits)
  MIPS: SmartMIPS: Disable assembler warnings
  MIPS: Move CPU topology macros to topology.h
  MIPS: Wire up new syscalls getrandom and memfd_create.
  MIPS: Fix a warning for virt_to_page
  arch/mips/net/bpf_jit.c: fix failure check
  MIPS: COP2: CPP macro safety fixes.
  MIPS: Kconfig: Select SMP symbols for CMP
  MIPS: ZBOOT: add missing <linux/string.h> include
  MIPS: IP28: Fix/clean spaces.h
  MIPS: IP28: Select correct L1_CACHE_SHIFT
  MIPS: BCM63xx: delete double assignment
  MIPS: Spelling s/confugrations/configurations/
  MIPS: OCTEON: make get_system_type() thread-safe
  MIPS: CPS: Initialize EVA before bringing up VPEs from secondary cores
  MIPS: Malta: EVA: Rename 'eva_entry' to 'platform_eva_init'
  MIPS: EVA: Add new EVA header
  MIPS: scall64-o32: Fix indirect syscall detection
  MIPS: syscall: Fix AUDIT value for O32 processes on MIPS64
