Commit c060f943 ("mm: use aligned zone start for pfn_to_bitidx
calculation") fixed out calculation of the index into the pageblock
bitmap when a !SPARSEMEM zome was not aligned to pageblock_nr_pages.

However, the _allocation_ of that bitmap had never taken this alignment
requirement into accout, so depending on the exact size and alignment of
the zone, the use of that index could then access past the allocation,
resulting in some very subtle memory corruption.

This was reported (and bisected) by Ingo Molnar: one of his random
config builds would hang with certain very specific kernel command line
options.

In the meantime, commit c060f943 has been marked for stable, so this
fix needs to be back-ported to the stable kernels that backported the
commit to use the right alignment.

     xen_iret for 32-bit PVOPS

  and two reverts:

   - Revert the PVonHVM kexec.  The patch introduces a regression with
     older hypervisor stacks, such as Xen 4.1."

  xen: remove redundant NULL check before unregister_and_remove_pcpu().
  x86/xen: don't assume %ds is usable in xen_iret for 32-bit PVOPS.

As reported by Klaus Schmidinger:
 "In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a
  device (using stb0899).  After this call I check 'errno' for
  EOPNOTSUPP to determine whether this device supports this call.  This
  used to work just fine, until a few months ago I noticed that my
  devices using stb0899 didn't display their signal quality in VDR's OSD
  any more.  After further investigation I found that
  ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but
  rather ENOTTY.  And since I stop getting the signal quality in case
  any unknown errno value appears, this broke my signal quality query
  function."

While the changes reflect what is there at:

  http://comments.gmane.org/gmane.linux.kernel/1235728

it does cause regression on userspace.  So, revert it to stop the
damage.

This reverts commit 177ffe50 ("[media] dvb_frontend: return -ENOTTY
for unimplement IOCTL").

This reverts commit 9d02b43d.

We are doing this b/c on 32-bit PVonHVM with older hypervisors
(Xen 4.1) it ends up bothing up the start_info. This is bad b/c
we use it for the time keeping, and the timekeeping code loops
forever - as the version field never changes. Olaf says to
revert it, so lets do that.

commit dd8004af: 'regulator: core: Log when a device causes a voltage
constraint fail', tried to print out some information about the
check consumer min/max uV fixup, however, it uses a garbage pointer
left over from list_for_each_entry leading to boot messages in the
form:

'[    2.079890] <RANDOM ASCII>: Restricting voltage, 3735899821-4294967295uV'

Because it references regulator->dev, it could potentially read memory from
anywhere causing a panic.

This patch instead uses rdev and the updated min/max uV values.

omapdrm uses "select" in Kconfig to enable omapdss. This doesn't work
correctly, as "select" forces omapdss to be enabled in the config even
if it normally could not be enabled because of missing Kconfig
dependencies.

This causes a build break on ARM, when using allyesconfig:

drivers/video/omap2/dss/dss.c: In function 'dss_calc_clock_div':
drivers/video/omap2/dss/dss.c:572:20: error: 'CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK' undeclared (first use in this function)
drivers/video/omap2/dss/dss.c:572:20: note: each undeclared identifier is reported only once for each function it appears in

Instead of using select, this patch changes omapdrm to use "depend
on".

commit 195e672a
   OMAPDSS: DPI: Remove cpu_is_xxxx checks

made the mistake of assuming that cpu_is_omap34xx() is exclusive of
other cpu_is_* predicates whereas it includes cpu_is_omap3630().

So on an omap3630, code that was previously enabled by
  if (cpu_is_omap34xx())
is now disabled as
  dss_has_feature(FEAT_DPI_USES_VDDS_DSI)
fails.

So add FEAT_DPI_USES_VDDS_DSI to omap3630_dss_feat_list.

There was a serious problem in samsung-laptop that its platform driver is
designed to run under BIOS and running under EFI can cause the machine to
become bricked or can cause Machine Check Exceptions.

    Discussion about this problem:
    https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557
    https://bugzilla.kernel.org/show_bug.cgi?id=47121

    The patches to fix this problem:
    efi: Make 'efi_enabled' a function to query EFI facilities
    83e68189

    samsung-laptop: Disable on EFI hardware
    e0094244

Unfortunately this problem comes back again if users specify "noefi" option.
This parameter clears EFI_BOOT and that driver continues to run even if running
under EFI. Refer to the document, this parameter should clear
EFI_RUNTIME_SERVICES instead.
