      kbuild: fix ld-option function · 5b83df2b
      Antony Pavlov authored
      The kbuild's ld-option function is broken because
      the command
        $(CC) /dev/null -c -o "$$TMPO"
      does not create object file!
      I have used a relatively old mips gcc 3.4.6 cross-compiler
      and a relatively new gcc 4.7.2 to check this fact
      but the results are the same.
        $ rm /tmp/1.o
        $ mips-linux-gcc /dev/null -c -o /tmp/1.o
        mips-linux-gcc: /dev/null: linker input file unused because linking not done
        $ ls -la /tmp/1.o
        ls: cannot access /tmp/1.o: No such file or directory
      We can easily fix the problem by adding
      the '-x c' compiler option.
        $ rm /tmp/1.o
        $ mips-linux-gcc -x c /dev/null -c -o /tmp/1.o
        $ ls -la /tmp/1.o
        -rw-r--r-- 1 antony antony 778 Apr  2 20:40 /tmp/1.o
      Also fix wrong ld-option example.

      perf,x86: fix link failure for non-Intel configs · 6c4d3bc9

      Commit 1d9d8639
       ("perf,x86: fix kernel crash with PEBS/BTS after
      suspend/resume") introduces a link failure since
      perf_restore_debug_store() is only defined for CONFIG_CPU_SUP_INTEL:
      	arch/x86/power/built-in.o: In function `restore_processor_state':
      	(.text+0x45c): undefined reference to `perf_restore_debug_store'
      Fix it by defining the dummy function appropriately.

      perf,x86: fix wrmsr_on_cpu() warning on suspend/resume · 2a6e06b2
      Linus Torvalds authored
      Commit 1d9d8639
       ("perf,x86: fix kernel crash with PEBS/BTS after
      suspend/resume") fixed a crash when doing PEBS performance profiling
      after resuming, but in using init_debug_store_on_cpu() to restore the
      DS_AREA mtrr it also resulted in a new WARN_ON() triggering.
      init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU
      cross-calls to do the MSR update.  Which is not really valid at the
      early resume stage, and the warning is quite reasonable.  Now, it all
      happens to _work_, for the simple reason that smp_call_function_single()
      ends up just doing the call directly on the CPU when the CPU number
      matches, but we really should just do the wrmsr() directly instead.
      This duplicates the wrmsr() logic, but hopefully we can just remove the
      wrmsr_on_cpu() version eventually.

      Btrfs: fix warning of free_extent_map · 3b277594
      Liu Bo authored
      Users report that an extent map's list is still linked when it's actually
      going to be freed from cache.
      The story is that
      a) when we're going to drop an extent map and may split this large one into
      smaller ems, and if this large one is flagged as EXTENT_FLAG_LOGGING which means
      that it's on the list to be logged, then the smaller ems split from it will also
      be flagged as EXTENT_FLAG_LOGGING, and this is _not_ expected.
      b) we'll keep ems from unlinking the list and freeing when they are flagged with
      EXTENT_FLAG_LOGGING, because the log code holds one reference.
      The end result is the warning, but the truth is that we set the flag
      EXTENT_FLAG_LOGGING only during fsync.
      So clear flag EXTENT_FLAG_LOGGING for extent maps split from a large one.

        that distributions like Arch linux use module aliases when

        mounted with ext4 would not result in the ext4 module being put into

      idr: idr_alloc() shouldn't trigger lowmem warning when preloaded · 59bfbcf0
      Tejun Heo authored
      GFP_NOIO is often used for idr_alloc() inside preloaded section as the
      allocation mask doesn't really matter.  If the idr tree needs to be
      expanded, idr_alloc() first tries to allocate using the specified
      allocation mask and if it fails falls back to the preloaded buffer.  This
      order prevent non-preloading idr_alloc() users from taking advantage of
      preloading ones by using preload buffer without filling it shifting the
      burden of allocation to the preload users.
      Unfortunately, this allowed/expected-to-fail kmem_cache allocation ends up
      generating spurious slab lowmem warning before succeeding the request from
      the preload buffer.
      This patch makes idr_layer_alloc() add __GFP_NOWARN to the first
      kmem_cache attempt and try kmem_cache again w/o __GFP_NOWARN after
      allocation from preload_buffer fails so that lowmem warning is generated
      if not suppressed by the original @gfp_mask.
