      hostap: fix "registers" registration in procfs · 23f40dc6
      Mathieu Chouquet-Stringer authored
      The "registers" entry was incorrectly created in the procfs root instead
      of the device specific directory.  Move "registers" registration
      immediately after the containing procfs directory is created.

      isdn/capi: Return proper errnos on module init. · 066b2118
      Marcin Slusarz authored
      cdebug_init() is called from kcapi_init() which is module
      initialization function, so it must return negative values on errors.

      hysdn: Remove cli()/sti() calls. · a9dd7fe2
      Mark Asselstine authored
      The use of cli()/sti() within the do/while was a way to ensure
      interrupts were only disabled for short periods of time while the bulk
      of the time interrupts were free to occur.  The use of the spin lock
      has eliminated the need to play with interrupts in this way while
      still allowing for IO to be protected.
      
      The remaining 3 sti() calls seem unneeded now that at no other point
      in the driver is there a call to cli().

      atm: Cleanup atm_tcp.h and atm.h for userspace. · a1a61a43
      Mike Frysinger authored
      The atm_tcp.h uses types from linux/atm.h, but does not include it.
      It should also use the standard __u## types from linux/types.h rather
      than the uint##_t types since the former can be found with the kernel
      already.
      
      Same goes for linux/atm.h.  The linux/socket.h include there also gets
      dropped as atm.h does not actually use anything from socket.h.

      sysfs: remove error messages for -EEXIST case · 0599ad53
      Stephen Hemminger authored
      It is possible that the entry in sysfs already exists, one case of this is
      when a network device is renamed to bonding_masters. Anyway, in this case
      the proper error path is for device_rename to return an error code, not to
      generate bogus backtrace and errors.
      
      Also, to avoid possible races, the create link should be done before the
      remove link. This makes a device rename atomic operation like other renames.

      Remove blkdev warning triggered by using md · e7e72bf6
      Neil Brown authored
      As setting and clearing queue flags now requires that we hold a spinlock
      on the queue, and as blk_queue_stack_limits is called without that lock,
      get the lock inside blk_queue_stack_limits.
      
      For blk_queue_stack_limits to be able to find the right lock, each md
      personality needs to set q->queue_lock to point to the appropriate lock.
      Those personalities which didn't previously use a spin_lock, us
      q->__queue_lock.  So always initialise that lock when allocated.
      
      With this in place, setting/clearing of the QUEUE_FLAG_PLUGGED bit will no
      longer cause warnings as it will be clear that the proper lock is held.
      
      Thanks to Dan Williams for review and fixing the silly bugs.

      memory_hotplug: always initialize pageblock bitmap · 76cdd58e
      Heiko Carstens authored
      Trying to online a new memory section that was added via memory hotplug
      sometimes results in crashes when the new pages are added via __free_page.
       Reason for that is that the pageblock bitmap isn't initialized and hence
      contains random stuff.  That means that get_pageblock_migratetype()
      returns also random stuff and therefore
      
      	list_add(&page->lru,
      		&zone->free_area[order].free_list[migratetype]);
      
      in __free_one_page() tries to do a list_add to something that isn't even
      necessarily a list.
      
      This happens since 86051ca5 ("mm: fix
      usemap initialization") which makes sure that the pageblock bitmap gets
      only initialized for pages present in a zone.  Unfortunately for hot-added
      memory the zones "grow" after the memmap and the pageblock memmap have
      been initialized.  Which means that the new pages have an unitialized
      bitmap.  To solve this the calls to grow_zone_span() and grow_pgdat_span()
      are moved to __add_zone() just before the initialization happens.
      
      The patch also moves the two functions since __add_zone() is the only
      caller and I didn't want to add a forward declaration.

      mprotect: prevent alteration of the PAT bits · 1c12c4cf
      Venki Pallipadi authored
      There is a defect in mprotect, which lets the user change the page cache
      type bits by-passing the kernel reserve_memtype and free_memtype
      wrappers.  Fix the problem by not letting mprotect change the PAT bits.

      per_cpu: fix DEFINE_PER_CPU_SHARED_ALIGNED for modules · 44c81433
      Eric Dumazet authored
      Current module loader lookups ".data.percpu" ELF section to perform
      per_cpu relocation.  But DEFINE_PER_CPU_SHARED_ALIGNED() uses another
      section (".data.percpu.shared_aligned"), currently only handled in
      vmlinux.lds, not by module loader.
      
      To correct this problem, instead of adding logic into module loader, or
      using at build time a module.lds file for all arches to group
      ".data.percpu.shared_aligned" into ".data.percpu", just use ".data.percpu"
      for modules.
      
      Alignment requirements are correctly handled by ld and module loader.

      memory_hotplug: check for walk_memory_resource() failure in online_pages() · fd8a4221
      Geoff Levand authored
      Add a check to online_pages() to test for failure of
      walk_memory_resource().  This fixes a condition where a failure
      of walk_memory_resource() can lead to online_pages() returning
      success without the requested pages being onlined.

      lib: create common ascii hex array · 3fc95772
      Harvey Harrison authored
      Add a common hex array in hexdump.c so everyone can use it.
      
      Add a common hi/lo helper to avoid the shifting masking that is
      done to get the upper and lower nibbles of a byte value.
      
      Pull the pack_hex_byte helper from kgdb as it is opencoded many
      places in the tree that will be consolidated.
