45cac65b0f readahead: fault retry breaks mmap file read random detection
.fault now can retry.  The retry can break state machine of .fault.  In
filemap_fault, if page is miss, ra->mmap_miss is increased.  In the second
try, since the page is in page cache now, ra->mmap_miss is decreased.  And
these are done in one fault, so we can't detect random mmap file access.

Add a new flag to indicate .fault is tried once.  In the second try, skip
ra->mmap_miss decreasing.  The filemap_fault state machine is ok with it.

I only tested x86, didn't test other archs, but looks the change for other
archs is obvious, but who knows :)

50e0d10232 This has three changes for asm-generic that did not really fit into any
other branch as normal asm-generic changes do. One is a fix for a
 build warning, the other two are more interesting:
 
 * A patch from Mark Brown to allow using the common clock infrastructure
 on all architectures, so we can use the clock API in architecture
 independent device drivers.
 
 * The UAPI split patches from David Howells for the asm-generic files.
 There are other architecture specific series that are going through
 the arch maintainer tree and that depend on this one.
 
 There may be a few small merge conflicts between Mark's patch and
 the following arch header file split patches. In each case the solution
 will be to keep the new "generic-y += clkdev.h" line, even if it
 ends up being the only line in the Kbuild file.

16f3e95b32 cross-arch: don't corrupt personality flags upon exec()
Historically, the top three bytes of personality have been used for
things such as ADDR_NO_RANDOMIZE, which made sense only for specific
architectures.

We now however have a flag there that is general no matter the
architecture (UNAME26); generally we have to be careful to preserve the
personality flags across exec().

This patch tries to fix all architectures that forcefully overwrite
personality flags during exec() (ppc32 and s390 have been fixed recently
by commits f9783ec862 ("[S390] Do not clobber personality flags on
exec") and 59e4c3a2fe ("powerpc/32: Don't clobber personality flags on
exec") in a similar way already).

Merge tag 'uapi-prep-20121002' of git://git.infradead.org/users/dhowells/linux-headers

Pull preparatory patches for user API disintegration from David Howells:
 "The patches herein prepare for the extraction of the Userspace API
  bits from the various header files named in the Kbuild files.

  New subdirectories are created under either include/uapi/ or
  arch/x/include/uapi/ that correspond to the subdirectory containing
  that file under include/ or arch/x/include/.

  The new subdirs under the uapi/ directory are populated with Kbuild
  files that mostly do nothing at this time.  Further patches will
  disintegrate the headers in each original directory and fill in the
  Kbuild files as they do it.

  These patches also:

   (1) fix up #inclusions of "foo.h" rather than <foo.h>.

   (2) Remove some redundant #includes from the DRM code.

   (3) Make the kernel build infrastructure handle Kbuild files both in
       the old places and the new UAPI place that both specify headers
       to be exported.

   (4) Fix some kernel tools that #include kernel headers during their
       build.

  I have compile tested this with allyesconfig against x86_64,
  allmodconfig against i386 and a scattering of additional defconfigs of
  other arches.  Prepared for main script

e7a570ff7d asm-generic: Add default clkdev.h
Ease the deployment of clkdev by providing a default asm/clkdev.h for
use if the arch does not have an include/asm/clkdev.h.

Due to limitations in Kbuild we manually add clkdev.h to all
architectures that don't have one rather than having the header appear
by default.

d878d6dace m68k: switch to generic sys_execve()/kernel_execve()
The tricky part here is that task_pt_regs() on m68k works *only* for
process inside do_signal().  However, we need something much simpler -
pt_regs of a process inside do_signal() may be at different offsets
from the stack bottom, depending on the way we'd entered the kernel,
but for a task inside sys_execve() it *is* at constant offset.
Moreover, for a kernel thread about to become a userland process the
same location is also fine - setting sp to that will leave the kernel
stack pointer at the very bottom of the kernel stack when we finally
switch to userland.

0973c687e0 m68k: always set stack frame format for ColdFire on thread start
The stack frame "format" field needs to be explicitly set on thread creation
on ColdFire. For a normal long word aligned user stack pointer the frame
format is 0x4.

We were doing this for non-MMU ColdFire, but not for the case with MMU enabled.
So fix it so we always do it if targeting ColdFire.

The old code happend to rely on the stack frame format being inhereted from
the process calling exec. Furture changes means that may not always work,
so we really do want to set it explicitly.

786d35d45c Make most arch asm/module.h files use asm-generic/module.h
Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.

Also, use the generic definition mod_arch_specific where possible.

To this end, I've defined three new config bools:

 (*) HAVE_MOD_ARCH_SPECIFIC

     Arches define this if they don't want to use the empty generic
     mod_arch_specific struct.

 (*) MODULES_USE_ELF_RELA

     Arches define this if their modules can contain RELA records.  This causes
     the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
     defined by the arch rather than have the core emit an error message.

 (*) MODULES_USE_ELF_REL

     Arches define this if their modules can contain REL records.  This causes
     the Elf_Rel mapping to be emitted and allows apply_relocate() to be
     defined by the arch rather than have the core emit an error message.

Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.

With this, some arch asm/module.h files can be deleted entirely and replaced
with a generic-y marker in the arch Kbuild file.

Additionally, I have removed the bits from m32r and score that handle the
unsupported type of relocation record as that's now handled centrally.

041a89a419 m68knommu: make ColdFire 5249 MBAR2 register definitions absolute addresses
Make the ColdFire 5249 MBAR peripheral register definitions absolute
addresses, instead of offsets into the region.

The various ColdFire parts use different methods to address the internal
registers, some are absolute, some are relative to peripheral regions
which can be mapped at different address ranges (such as the MBAR and IPSBAR
registers). We don't want to deal with this in the code when we are
accessing these registers, so make all register definitions the absolute
address - factoring out whether it is an offset into a peripheral region.

This makes them all consistently defined, and reduces the occasional bugs
caused by inconsistent definition of the register addresses.

d72a5abb7e m68knommu: make remaining ColdFire 5272 register definitions absolute addresses
Make the remaining definitions of the 5272 ColdFire registers absolute
addresses. Currently some are relative to the MBAR peripheral region.

The various ColdFire parts use different methods to address the internal
registers, some are absolute, some are relative to peripheral regions
which can be mapped at different address ranges (such as the MBAR and IPSBAR
registers). We don't want to deal with this in the code when we are
accessing these registers, so make all register definitions the absolute
address - factoring out whether it is an offset into a peripheral region.

This makes them all consistently defined, and reduces the occasional bugs
caused by inconsistent definition of the register addresses.
