      x86: remove always-defined CONFIG_AS_CFI · 0f2661c4
      Masahiro Yamada authored
      CONFIG_AS_CFI was introduced by commit e2414910 ("[PATCH] x86:
      Detect CFI support in the assembler at runtime"), and extended by
      commit f0f12d85 ("x86_64: Check for .cfi_rel_offset in CFI probe").
      
      We raise the minimal supported binutils version from time to time.
      The last bump was commit 1fb12b35 ("kbuild: Raise the minimum
      required binutils version to 2.21").
      
      I confirmed the code in $(call as-instr,...) can be assembled by the
      binutils 2.21 assembler and also by LLVM integrated assembler.
      
      Remove CONFIG_AS_CFI, which is always defined.

      x86: remove unneeded defined(__ASSEMBLY__) check from asm/dwarf2.h · 418d6e29
      Masahiro Yamada authored
      This header file has the following check at the top:
      
        #ifndef __ASSEMBLY__
        #warning "asm/dwarf2.h should be only included in pure assembly files"
        #endif
      
      So, we expect defined(__ASSEMBLY__) is always true.

      lib/raid6/test: fix build on distros whose /bin/sh is not bash · 06bd48b6
      Masahiro Yamada authored
      You can build a user-space test program for the raid6 library code,
      like this:
      
        $ cd lib/raid6/test
        $ make
      
      The command in $(shell ...) function is evaluated by /bin/sh by default.
      (or, you can specify the shell by passing SHELL=<shell> from command line)
      
      Currently '>&/dev/null' is used to sink both stdout and stderr. Because
      this code is bash-ism, it only works when /bin/sh is a symbolic link to
      bash (this is the case on RHEL etc.)
      
      This does not work on Ubuntu where /bin/sh is a symbolic link to dash.
      
      I see lots of
      
        /bin/sh: 1: Syntax error: Bad fd number
      
      and
      
        warning "your version of binutils lacks ... support"
      
      Replace it with portable '>/dev/null 2>&1'.

      mm/gup: Mark lock taken only after a successful retake · c7b6a566
      Peter Xu authored
      It's definitely incorrect to mark the lock as taken even if
      down_read_killable() failed.
      
      This wass overlooked when we switched from down_read() to
      down_read_killable() because down_read() won't fail while
      down_read_killable() could.

      mm/mempolicy: Allow lookup_node() to handle fatal signal · ba841078
      Peter Xu authored
      lookup_node() uses gup to pin the page and get node information.  It
      checks against ret>=0 assuming the page will be filled in.  However it's
      also possible that gup will return zero, for example, when the thread is
      quickly killed with a fatal signal.  Teach lookup_node() to gracefully
      return an error -EFAULT if it happens.
      
      Meanwhile, initialize "page" to NULL to avoid potential risk of
      exploiting the pointer.
      
      Fixes: 4426e945 ("mm/gup: allow VM_FAULT_RETRY for multiple times")
