072441e21d mm: move shmem prototypes to shmem_fs.h
Before adding any more global entry points into shmem.c, gather such
prototypes into shmem_fs.h.  Remove mm's own declarations from swap.h,
but for now leave the ones in mm.h: because shmem_file_setup() and
shmem_zero_setup() are called from various places, and we should not
force other subsystems to update immediately.

d4620396d7 Staging: brcm80211: disable drivers except for X86 or MIPS platforms
As David points out, the driver is also broken on SPARC, so might
as well just only enable it on platforms where people have reported it
working, instead of trying to list all of the ones where it doesn't
work, as the working platform list is much smaller...

15e5201dfd Staging: brcm80211: disable drivers for PPC platforms
Right now, bad things happen if you try to build these drivers for the
PPC platform as it seems that the code only has been tested and built on
the MIPS big endian platform.

So disable it on the PPC32 and PPC64 platforms for now, hopefully this
will be resolved in the future as I'm sure someone will want to use
these chips with that platform someday.

Hence IIO_TRIGGER should depend on GENERIC_HARDIRQS.
But as IIO_TRIGGER and IIO_RING_BUFFER form a maze of dependencies and selects,
just make the whole IIO subsystem depend on GENERIC_HARDIRQS.

This dependency also covers !S390, so that one can be removed again.

6fab3e1fbc Staging: Comedi: Build only on arches providing PAGE_KERNEL_NOCACHE
On architectures that don't define PAGE_KERNEL_NOCACHE, the Comedi driver turns
into tragedy:

  CC [M]  drivers/staging/comedi/drivers.o
drivers/staging/comedi/drivers.c: In function ‘comedi_buf_alloc’:
drivers/staging/comedi/drivers.c:505:41: error: ‘PAGE_KERNEL_NOCACHE’ undeclared (first use in this function)
drivers/staging/comedi/drivers.c:505:41: note: each undeclared identifier is rep orted only once for each function it appears in
make[3]: *** [drivers/staging/comedi/drivers.o] Error 1

Restrict the driver to only those architectures that define PAGE_KERNEL_NOCACHE.

PAGE_KERNEL_NOCACHE is a kludge - some system architectures such as SGI IP27
are even uable to offer uncached operation - at least in the way an unwitting
driver might assume.  I haven't looked in details how the driver is using
the area vmaped with PAGE_KERNEL_NOCACHE but maybe doing it XFS-style using
cached memory and the flush_kernel_vmap_range / invalidate_kernel_vmap_range
APIs in conjunction with the DMA API is a practical alternative.

c6830c2260 Fix node_start/end_pfn() definition for mm/page_cgroup.c
commit 21a3c96 uses node_start/end_pfn(nid) for detection start/end
of nodes. But, it's not defined in linux/mmzone.h but defined in
/arch/???/include/mmzone.h which is included only under
CONFIG_NEED_MULTIPLE_NODES=y.

Then, we see
  mm/page_cgroup.c: In function 'page_cgroup_init':
  mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn'
  mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn'

So, fixiing page_cgroup.c is an idea...

But node_start_pfn()/node_end_pfn() is a very generic macro and
should be implemented in the same manner for all archs.
(m32r has different implementation...)

This patch removes definitions of node_start/end_pfn() in each archs
and defines a unified one in linux/mmzone.h. It's not under
CONFIG_NEED_MULTIPLE_NODES, now.

A result of macro expansion is here (mm/page_cgroup.c)

for !NUMA
 start_pfn = ((&contig_page_data)->node_start_pfn);
  end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});

for NUMA (x86-64)
  start_pfn = ((node_data[nid])->node_start_pfn);
  end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});

Changelog:
 - fixed to avoid using "nid" twice in node_end_pfn() macro.

      USB: EHCI: Support controllers with big endian capability regs

      The two first HC capability registers (CAPLENGTH and HCIVERSION)
      are defined as one 8-bit and one 16-bit register. Most HC
      implementations have selected to treat these registers as part
      of a 32-bit register, giving the same layout for both big and
      small endian systems.

      This patch adds a new quirk, big_endian_capbase, to support
      controllers with big endian register interfaces that treat
      HCIVERSION and CAPLENGTH as individual registers.

FT4232H has also it's own PID).

8b1ab60c76 usb/isp1760: Fix bug preventing the unlinking of control urbs
Both control and bulk transfers use isp1760 slots of type ATL, but the
driver unlink code for ATL slots only acts on urbs describing a bulk
transfer, letting the code for INT slots take care of the unlink instead,
which often ended up removing the interrupt transfer for root hub events
instead. That's not good, and gets fixed by this patch.

2f7e33d432 btrfs: fix inconsonant inode information
When iputting the inode, We may leave the delayed nodes if they have some
delayed items that have not been dealt with. So when the inode is read again,
we must look up the relative delayed node, and use the information in it to

cause that the same directory index number is allocated again, and hit the
following oops:

SCSI defines discard alignment as the offset to the first
optimal discard.  In the case of SD/MMC, that is always zero
which is the default.

SCSI defines discard granularity as a hint of a optimal
discard size.  That is much better expressed by the MMC
"preferred erase size" (pref_erase) field.

4a3dc6ef34 mmc: omap_hsmmc: fix ocr mask usage
The OMAP HSMMC driver uses an ocr_mask to determine the list of voltages
supported by the card. It populates this mask based on the list of
voltages supported by the regulator that supplies the voltage.

Commit 64be97822b (omap4 hsmmc: Update ocr mask for MMC2 for regulator
to use) passed a fixed ocr_mask from the OMAP4 SDP board file to limit
the voltage to 2.9-3.0 Volts, and updated the driver to use this mask
if provided, instead of using the regulator's supported voltages.

However the commit is buggy - the ocr_mask is overridden by the
regulator's capabilities anyway. Fix this.

(The bug shows up when a system-wide suspend is attempted on the OMAP4
SDP/Blaze platforms. The eMMC card comes up at 3V, but drops to 1.65V
after the system resumes).

297c7f2f15 mmc: sdio: fix runtime PM path during driver removal
After commit e1866b3 "PM / Runtime: Rework runtime PM handling
during driver removal" was introduced, the driver core stopped
incrementing the runtime PM usage counter of the device during
the invocation of the ->remove() callback.

This indirectly broke SDIO's runtime PM path during driver removal,
because no one calls _put_sync() anymore after ->remove() completes.

This means that the power of runtime-PM-managed SDIO cards is kept
high after their driver is removed (even if it was powered down
beforehand).

Fix that by directly calling _put_sync() when the last usage
counter is downref'ed by the SDIO bus.
