7084ebaa26 [POWERPC] Fix arch/ppc compilation - add typedef for pgtable_t
Commit 2f569afd9c ("CONFIG_HIGHPTE vs.
sub-page page tables.") breaks compilation of arch/ppc since it
introduces the pgtable_t type which was not added to arch/ppc.

This adds the missing typedef.

75ffe88d2b [POWERPC] PS3: Use system reboot on restart
The PS3 Other OS boot flag is not checked when an LPAR reboot is done,
so the ps3-boot-game-os utility fails to reboot the system into the
Game OS.  This fix changes the PS3 restart handler from requesting an
PS3_SM_NEXT_OP_LPAR_REBOOT to requesting an PS3_SM_NEXT_OP_SYS_REBOOT.

e5a21dd873 [POWERPC] PS3: Fix bootwrapper hang bug
Fix a bug in the lv1_get_repository_node_value() routine of the PS3
bootwrapper.  Changes in the PS3 system firmware 2.20 cause this bug
to hang the system when branching from the bootwrapper to the kernel
_start.

Since the video system has not yet been enabled at the time
the bug is hit, the system hangs with a blank screen.  Earlier
firmwares don't cause such a catastrophic failure, and so this
bug went undetected.

b2e3e658b3 Linux Kernel Markers: create modpost file
This adds some new magic in the MODPOST phase for CONFIG_MARKERS.  Analogous
to the Module.symvers file, the build will now write a Module.markers file
when CONFIG_MARKERS=y is set.  This file lists the name, defining module, and
format string of each marker, separated by \t characters.  This simple text
file can be used by offline build procedures for instrumentation code,
analogous to how System.map and Module.symvers can be useful to have for
kernels other than the one you are running right now.

The strings are made easy to extract by having the __trace_mark macro define
the name and format together in a single array called __mstrtab_* in the
__markers_strings section.  This is straightforward and reliable as long as
the marker structs are always defined by this macro.  It is an unreasonable
amount of hairy work to extract the string pointers from the __markers section
structs, which entails handling a relocation type for every machine under the
sun.

fb40bd78b0 Linux Kernel Markers: support multiple probes
RCU style multiple probes support for the Linux Kernel Markers.  Common case
(one probe) is still fast and does not require dynamic allocation or a
supplementary pointer dereference on the fast path.

- Move preempt disable from the marker site to the callback.

Since we now have an internal callback, move the preempt disable/enable to the
callback instead of the marker site.

Since the callback change is done asynchronously (passing from a handler that
supports arguments to a handler that does not setup the arguments is no
arguments are passed), we can safely update it even if it is outside the
preempt disable section.

- Move probe arm to probe connection. Now, a connected probe is automatically
  armed.

Remove MARK_MAX_FORMAT_LEN, unused.

This patch modifies the Linux Kernel Markers API : it removes the probe
"arm/disarm" and changes the probe function prototype : it now expects a
va_list * instead of a "...".

If we want to have more than one probe connected to a marker at a given
time (LTTng, or blktrace, ssytemtap) then we need this patch. Without it,
connecting a second probe handler to a marker will fail.

It allow us, for instance, to do interesting combinations :

Do standard tracing with LTTng and, eventually, to compute statistics
with SystemTAP, or to have a special trigger on an event that would call
a systemtap script which would stop flight recorder tracing.

/home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `free_netdev'
[ ... and many more ... ]

select strikes again. ipwireless selects PPP which in turn tries to select
SLHC, both of which are technically "protected" by an if NETDEVICES
in drivers/net/Kconfig. This leads to .config hilarity, with net suddenly
ending up in the SCSI menu:

	#
	# SCSI device support
	#
	# CONFIG_SCSI_DMA is not set
	# CONFIG_SCSI_NETLINK is not set
	CONFIG_PPP=y
	# CONFIG_PHONE is not set

Curiously the SLHC select from PPP doesn't seem to happen, as there's no
CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug? Caught with a
randconfig.

91d35dd93e moduleparam: fix alpha, ia64 and ppc64 compile failures
On alpha, ia64 and ppc64 only relocations to local data can go into
read-only sections. The vast majority of module parameters use the global
generic param_set_*/param_get_* functions, so the 'const' attribute for
struct kernel_param is not only useless, but it also causes compile
failures due to 'section type conflict' in those rare cases where
param_set/get are local functions.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=8964

aa02cd2d9b xtime_lock vs update_process_times
Commit d3d74453c3 ("hrtimer: fixup the
HRTIMER_CB_IRQSAFE_NO_SOFTIRQ fallback") broke several archs, and since
only Russell bothered to merge the fix, and Greg to ACK his arch, I'm
sending this for merger.

I have confirmation that the Alpha bit results in a booting kernel.
That leaves: blackfin, frv, sh and sparc untested.

The deadlock in question was found by Russell:

  IRQ handle
    -> timer_tick() - xtime seqlock held for write
      -> update_process_times()
        -> run_local_timers()
          -> hrtimer_run_queues()
            -> hrtimer_get_softirq_time() - tries to get a read lock

Now, Thomas assures me the fix is trivial, only do_timer() needs to be
done under the xtime_lock, and update_process_times() can savely be
removed from under it.

10270d4838 acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read()
The raw_pci_read() interface (as the raw_pci_ops->read() before it)
unconditionally fills in a 32-bit integer return value regardless of the
size of the operation requested.

So claiming to take a "void *" is wrong, as is passing in a pointer to
just a byte variable.

Noticed by pageexec when enabling -fstack-protector (which needs other
patches too to actually work, but that's a separate issue).

61c92814dc [SCSI] gdth: scan for scsi devices
The patch: "gdth: switch to modern scsi host registration"

missed one simple fact when moving a way from scsi_module.c.
That is to call scsi_scan_host() on the probed host.
With this the gdth driver from 2.6.24 is again able to
see drives and boot.

4de0d4a6d1 x86: EFI runtime code mapping enhancement
This patch enhances EFI runtime code memory mapping as following:

- Move __supported_pte_mask & _PAGE_NX checking before invoking
  runtime_code_page_mkexec(). This makes it possible for compiler to
  eliminate runtime_code_page_mkexec() on machine without NX support.

- Use set_memory_x/nx in early_mapping_set_exec(). This eliminates the
  duplicated implementation.

This patch has been tested on Intel x86_64 platform with EFI64/32
firmware.

e85f20518b x86: EFI: fix use of unitialized variable and the cache logic
Andi Kleen pointed out that the cache attribute logic is reverse in
efi_enter_virtual_mode(). This problem alone is harmless as we do not
(yet) do cache attribute conflict resolution. (This bug was not present
in the original EFI submission - I introduced it while fixing up rejects.)

While reviewing this code I noticed a second, worse problem: the use of
uninitialized md->virt_addr.

Fix both problems.

  keep the code uptodate and this fix is easy enough. ]

Use correct page sizes and masks for GB pages in try_preserve_large_page()

This prevents a boot hang on a GB capable system with CONFIG_DIRECT_GBPAGES

37cc8d7f96 x86/early_ioremap: don't assume we're using swapper_pg_dir
At the early stages of boot, before the kernel pagetable has been
fully initialized, a Xen kernel will still be running off the
Xen-provided pagetables rather than swapper_pg_dir[].  Therefore,
readback cr3 to determine the base of the pagetable rather than
assuming swapper_pg_dir[].
