Pull i2c changes from Wolfram Sang:

 - an arbitration driver.  While the driver is quite simple, it caused
   discussion if we need additional arbitration on top of the one
   specified in the I2C standard.  Conclusion is that I accept a few
   generic mechanisms, but not very specific ones.

 - the core lost the detach_adapter() call.  It has no users anymore and
   was in the way for other cleanups.  attach_adapter() is sadly still
   there since there are users waiting to be converted.

 - the core gained a bus recovery infrastructure.  I2C defines a way to
   recover if the data line is stalled.  This mechanism is now in the
   core and drivers can now pass some data to make use of it.

 - bigger driver cleanups for designware, s3c2410

 - removing superfluous refcounting from drivers

During early init, we would incorrectly set the NX bit even if the NX
feature was not supported.  Instead, only set this bit if NX is
actually available and enabled.  We already do very early detection of
the NX bit to enable it in EFER, this simply extends this detection to
the early page table mask.

The git commite7a5cd06
("x86-64, gdt: Store/load GDT for ACPI S3 or hibernate/resume path
is not needed.") assumes that for the hibernate path the booting
kernel and the resuming kernel MUST be the same. That is certainly
the case for a 32-bit kernel (see check_image_kernel and
CONFIG_ARCH_HIBERNATION_HEADER config option).

However for 64-bit kernels it is OK to have a different kernel
version (and size of the image) of the booting and resuming kernels.
Hence the above mentioned git commit introduces an regression.

This patch fixes it by introducing a 'struct desc_ptr gdt_desc'
back in the 'struct saved_context'. However instead of having in the
'save_processor_state' and 'restore_processor_state' the
store/load_gdt calls, we are only saving the GDT in the
save_processor_state.

For the restore path the lgdt operation is done in
hibernate_asm_[32|64].S in the 'restore_registers' path.

The apt reader of this description will recognize that only 64-bit
kernels need this treatment, not 32-bit. This patch adds the logic
in the 32-bit path to be more similar to 64-bit so that in the future
the unification process can take advantage of this.

Pull VFS updates from Al Viro,

Misc cleanups all over the place, mainly wrt /proc interfaces (switch
create_proc_entry to proc_create(), get rid of the deprecated
create_proc_read_entry() in favor of using proc_create_data() and
seq_file etc).

7kloc removed.

We moved the definition of shift_to_mmu_psize and mmu_psize_to_shift
out of hugetlbpage.c in patch "powerpc: New hugepage directory format".

These functions are not related to hugetlbpage and we want to use them
outside hugetlbpage.c We missed a definition for book3e when we moved
these functions. Add similar functions to mmu-book3e.h

We are getting low on cpu feature bits. So rather than add a separate bit for
every new Power8 feature, add a bit for arch 2.07 server catagory and use that
instead.

Hijack the value we had for BCTAR, but swap the value with CFAR so that all the
ARCH defines are together.

Note we don't touch CPU_FTR_TM, because it is conditionally enabled if
the kernel is built with TM support.

We do not want to take single step and branch-taken debug exception
in kernel exception code. But the address range check was not covering
all kernel exception handlers address range.

With this patch we defined the interrupt_end label which defines the
end on kernel exception code. So now we check interrupt_base to
interrupt_end range for not handling debug exception in kernel
exception entry.

Pull x86/efi changes from Peter Anvin:
 "The bulk of these changes are cleaning up the efivars handling and
  breaking it up into a tree of files.  There are a number of fixes as
  well.

  The entire changeset is pretty big, but most of it is code movement.

  Several of these commits are quite new; the history got very messed up
  due to a mismerge with the urgent changes for rc8 which completely
  broke IA64, and so Ingo requested that we rebase it to straighten it
  out."

* 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  efi: remove "kfree(NULL)"
  efi: locking fix in efivar_entry_set_safe()
  efi, pstore: Read data from variable store before memcpy()

  efi, pstore: Initialise 'entry' before iterating

Al's commit e1b5bb6d ("consolidate cond_syscall and SYSCALL_ALIAS
declarations") broke the build on blackfin and metag due to the
following code:

  #ifndef SYMBOL_NAME
  #ifdef CONFIG_SYMBOL_PREFIX
  #define SYMBOL_NAME(x) CONFIG_SYMBOL_PREFIX ## x
  #else
  #define SYMBOL_NAME(x) x
  #endif
  #endif
  #define __SYMBOL_NAME(x) __stringify(SYMBOL_NAME(x))

__stringify literally stringifies CONFIG_SYMBOL_PREFIX ##x, so you get
lines like this in kernel/sys_ni.s:

  .weak CONFIG_SYMBOL_PREFIXsys_quotactl
  .set CONFIG_SYMBOL_PREFIXsys_quotactl,CONFIG_SYMBOL_PREFIXsys_ni_syscall

The patches in Rusty's modules-next tree such as "CONFIG_SYMBOL_PREFIX:
cleanup." cleans up the whole mess around symbol prefixes, so this patch
just attempts to fix the build in the meantime.

The intermediate definition of SYMBOL_NAME above isn't used and is
incorrect when CONFIG_SYMBOL_PREFIX is defined as CONFIG_SYMBOL_PREFIX
is a quoted string literal, so define __SYMBOL_NAME directly depending
on CONFIG_SYMBOL_PREFIX.

Make the PROC_I() and PDE() macros internal to procfs.  This means making
PDE_DATA() out of line.  This could be made more optimal by storing
PDE()->data into inode->i_private.

Also provide a __PDE_DATA() that is inline and internal to procfs.

Supply a function (proc_remove()) to remove a proc entry (and any subtree
rooted there) by proc_dir_entry pointer rather than by name and (optionally)
root dir entry pointer.  This allows us to eliminate all remaining pde->name

Clean up the pseries scanlog driver's use of procfs:

 (1) Don't need to save the proc_dir_entry pointer as we have the filename to
     remove with.

 (2) Save the scan log buffer pointer in a static variable (there is only one
     of it) and don't save it in the PDE (which doesn't have a destructor).

Clean up some of the problems with the rtas_flash driver:

 (1) It shouldn't fiddle with the internals of the procfs filesystem (altering
     pde->count).

 (2) If pid namespaces are in effect, then you can get multiple inodes
     connected to a single pde, thereby rendering the pde->count > 2 test
     useless.

 (3) The pde->count fudging doesn't work for forked, dup'd or cloned file
     descriptors, so add static mutexes and use them to wrap access to the
     driver through read, write and release methods.

 (4) The driver can only handle one device, so allocate most of the data
     previously attached to the pde->data as static variables instead (though
     allocate the validation data buffer with kmalloc).

 (5) We don't need to save the pde pointers as long as we have the filenames
     available for removal.

 (6) Don't try to multiplex what the update file read method does based on the
     filename.  Instead provide separate file ops and split the function.

Whilst we're at it, tabulate the procfile information and loop through it when
creating or destroying them rather than manually coding each one.
