      sparc64: Fix bootup crash on sun4v. · 9e0daff3

      The DS driver registers as a subsys_initcall() but this can be too
      early, in particular this risks registering before we've had a chance
      to allocate and setup module_kset in kernel/params.c which is
      performed also as a subsyts_initcall().
      
      Register DS using device_initcall() insteal.

      kconfig: delete last traces of __enabled_ from autoconf.h · e4757cab
      Paul Gortmaker authored
      
      
      We've now fixed IS_ENABLED() and friends to not require any special
      "__enabled_" prefixed versions of the normal Kconfig options, so delete
      the last traces of them being generated.

      This reverts commit 953742c8
      
      .
      
      Dumping two lines into autoconf.h for all existing Kconfig options
      results in a giant file (~16k lines) we have to process each time we
      compile something.  We've weaned IS_ENABLED() and similar off of
      requiring the __enabled_ definitions so now we can revert the change
      which caused all the extra lines.

      kconfig: fix IS_ENABLED to not require all options to be defined · 69349c2d
      Paul Gortmaker authored
      
      
      Using IS_ENABLED() within C (vs.  within CPP #if statements) in its
      current form requires us to actually define every possible bool/tristate
      Kconfig option twice (__enabled_* and __enabled_*_MODULE variants).
      
      This results in a huge autoconf.h file, on the order of 16k lines for a
      x86_64 defconfig.
      
      Fixing IS_ENABLED to be able to work on the smaller subset of just
      things that we really have defined is step one to fixing this.  Which
      means it has to not choke when fed non-enabled options, such as:
      
        include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef]
      
      The original prototype of how to implement a C and preprocessor
      compatible way of doing this came from the Google+ user "comex ." in
      response to Linus' crowdsourcing challenge for a possible improvement on
      his earlier C specific solution:
      
      	#define config_enabled(x)       (__stringify(x)[0] == '1')
      
      In this implementation, I've chosen variable names that hopefully make
      how it works more understandable.

      sizeof(void*) returns an unsigned long, but it was being used as a width parameter to a "%-*s" format string which requires an int.  On 64 bit platforms this causes a type mismatch:

          'int', but argument 6 has type 'long unsigned int'
      
      This change casts the size to an int so printf gets the right data type.

      staging: android: fix mem leaks in __persistent_ram_init() · 474a8988
      Jesper Juhl authored
      
      
      If, in __persistent_ram_init(), the call to
      persistent_ram_buffer_init() fails or the call to
      persistent_ram_init_ecc() fails then we fail to free the memory we
      allocated to 'prz' with kzalloc() - thus leaking it.
      
      To prevent the leaks I consolidated all error exits from the function
      at a 'err:' label at the end and made all error cases jump to that
      label where we can then make sure we always free 'prz'. This is safe
      since all the situations where the code bails out happen before 'prz'
      has been stored anywhere and although we'll do a redundant kfree(NULL)
      call in the case of kzalloc() itself failing that's OK since kfree()
      deals gracefully with NULL pointers and I felt it was more important
      to keep all error exits at a single location than to avoid that one
      harmless/redundant kfree() on a error path.

      Also remove a pointless cast (to type 'PSNodeList') of a kmalloc()
      return value - kmalloc() returns a void pointer that is implicitly

       5) We made a facility for layers like wireless to say how much tailroom
          they need in the SKB for link layer stuff such as wireless
          encryption etc., but TCP works hard to fill every SKB out to the end
          defeating this specification.
      
          This leads to every TCP packet getting reallocated by the wireless
          code in order to have the right amount of tailroom available.
      
          Fix TCP to only fill SKBs out to the real amount of data area it
          asked for during the allocation, this way it won't eat into the
          slack added for the device's tailroom needs.

      panic: fix stack dump print on direct call to panic() · 026ee1f6
      Jason Wessel authored
      Commit 6e6f0a1f
      
       ("panic: don't print redundant backtraces on oops")
      causes a regression where no stack trace will be printed at all for the
      case where kernel code calls panic() directly while not processing an
      oops, and of course there are 100's of instances of this type of call.
      
      The original commit executed the check (!oops_in_progress), but this will
      always be false because just before the dump_stack() there is a call to
      bust_spinlocks(1), which does the following:
      
        void __attribute__((weak)) bust_spinlocks(int yes)
        {
      	if (yes) {
      		++oops_in_progress;
      
      The proper way to resolve the problem that original commit tried to
      solve is to avoid printing a stack dump from panic() when the either of
      the following conditions is true:
      
        1) TAINT_DIE has been set (this is done by oops_end())
           This indicates and oops has already been printed.
        2) oops_in_progress > 1
           This guards against the rare case where panic() is invoked
           a second time, or in between oops_begin() and oops_end()

      Ying Han authored
      This reverts commit c38446cc
      
      .
      
      Before the commit, the code makes senses to me but not after the commit.
      The "nr_reclaimed" is the number of pages reclaimed by scanning through
      the memcg's lru lists.  The "nr_to_reclaim" is the target value for the
      whole function.  For example, we like to early break the reclaim if
      reclaimed 32 pages under direct reclaim (not DEF_PRIORITY).
      
      After the reverted commit, the target "nr_to_reclaim" is decremented each
      time by "nr_reclaimed" but we still use it to compare the "nr_reclaimed".
      It just doesn't make sense to me...

      hugetlb: fix race condition in hugetlb_fault() · 66aebce7
      Chris Metcalf authored
      
      
      The race is as follows:
      
      Suppose a multi-threaded task forks a new process (on cpu A), thus
      bumping up the ref count on all the pages.  While the fork is occurring
      (and thus we have marked all the PTEs as read-only), another thread in
      the original process (on cpu B) tries to write to a huge page, taking an
      access violation from the write-protect and calling hugetlb_cow().  Now,
      suppose the fork() fails.  It will undo the COW and decrement the ref
      count on the pages, so the ref count on the huge page drops back to 1.
      Meanwhile hugetlb_cow() also decrements the ref count by one on the
      original page, since the original address space doesn't need it any
      more, having copied a new page to replace the original page.  This
      leaves the ref count at zero, and when we call unlock_page(), we panic.

      drivers/rtc/rtc-twl.c: use static register while reading time · f3ec434c
      Konstantin Shlyakhovoy authored
      
      
      RTC stores time and date in several registers.  Due to the fact that
      these registers can't be read instantaneously, there is a chance that
      reading from counting registers gives an error of one minute, one hour,
      one day, etc.
      
      To address this issue, the RTC has hardware support to copy the RTC
      counting registers to static shadowed registers.  The current
      implementation does not use this feature, and in a stress test, we can
      reproduce this error at a rate of around two times per 300000 readings.
      
      Fix the implementation to ensure that the right snapshot of time is
      captured.

      We should use the accessor res_counter_read_u64 for that.
      
      Although a purely cosmetic change is sometimes better delayed, to avoid
      conflicting with other people's work, we are starting to have people
      touching this code as well, and reproducing the open code behavior
      because that's the standard =)

      drivers/char/random.c: fix boot id uniqueness race · 44e4360f
      Mathieu Desnoyers authored
      
      
      /proc/sys/kernel/random/boot_id can be read concurrently by userspace
      processes.  If two (or more) user-space processes concurrently read
      boot_id when sysctl_bootid is not yet assigned, a race can occur making
      boot_id differ between the reads.  Because the whole point of the boot id
      is to be unique across a kernel execution, fix this by protecting this
      operation with a spinlock.
      
      Given that this operation is not frequently used, hitting the spinlock
      on each call should not be an issue.
