touchscreen: Add improved touch boost interface

Lock the CPU Frequency to a set speed when an input event is detected.

Rewrite the entire interface again to work on MXT224E.

We can now configure the timeout interval and the frequency to boost to
via sysfs.

Disabled by default to save battery.

-> freq_boost: CPU Speed to set to when touch input event is detected
(800Mhz Default)

-> touchboost_timeout: Keep the freq locked for the set time (Max 10 Seconds)
(0 milliseconds default)

-> touchboost_status: Toggle to turn on/off

ftrace: Be first to run code modification on modules

commit c1bf08ac26e92122faab9f6c32ea8aba94612dae upstream.

If some other kernel subsystem has a module notifier, and adds a kprobe
to a ftrace mcount point (now that kprobes work on ftrace points),
when the ftrace notifier runs it will fail and disable ftrace, as well
as kprobes that are attached to ftrace points.

Here's the error:

 ftrace failed to modify [<ffffffffa0180000>] init_once+0x0/0x20 [fat]
  actual: cc:bb:d2:4b:e1

A kprobe was added to the init_once() function in the fat module on load.
But this happened before ftrace could have touched the code. As ftrace
didn't run yet, the kprobe system had no idea it was a ftrace point and
simply added a breakpoint to the code (0xcc in the cc:bb:d2:4b:e1).

Then when ftrace went to modify the location from a call to mcount/fentry
into a nop, it didn't see a call op, but instead it saw the breakpoint op
and not knowing what to do with it, ftrace shut itself down.

The solution is to simply give the ftrace module notifier the max priority.
This should have been done regardless, as the core code ftrace modification
also happens very early on in boot up. This makes the module modification
closer to core modification.

PCI: Allow pcie_aspm=force even when FADT indicates it is unsupported

commit 9e16721498b0c3d3ebfa0b503c63d35c0a4c0642 upstream.

Right now using pcie_aspm=force will not enable ASPM if the FADT indicates
ASPM is unsupported.  However, the semantics of force should probably allow
for this, especially as they did before 3c076351c4 ("PCI: Rework ASPM
disable code")

This patch just skips the clearing of any ASPM setup that the firmware has
carried out on this bus if pcie_aspm=force is being used.

USB: UHCI: fix IRQ race during initialization

commit 0f815a0a700bc10547449bde6c106051a035a1b9 upstream.

This patch (as1644) fixes a race that occurs during startup in
uhci-hcd.  If the IRQ line is shared with other devices, it's possible
for the handler routine to be called before the data structures are
fully initialized.

The problem is fixed by adding a check to the IRQ handler routine.  If
the initialization hasn't finished yet, the routine will return
immediately.

SCSI: sd: Reshuffle init_sd to avoid crash

commit afd5e34b2bb34881d3a789e62486814a49b47faa upstream.

scsi_register_driver will register a prep_fn() function, which
in turn migh need to use the sd_cdp_pool for DIF.
Which hasn't been initialised at this point, leading to
a crash. So reshuffle the init_sd() and exit_sd() paths
to have the driver registered last.

As of version 2.6 of the SMBIOS specification, the first 3 fields of the
UUID are supposed to be little-endian encoded.

Also a minor fix to match variable meaning and mute checkpatch.pl
