Some BIOS versions/Vaio models apparently ship with two nearly identical
functions to handle backlight related controls.
The only difference seems to be:
        If (LEqual (BUF1, 0x40))
        {
            Store (0x40, P80H)
            Store (BUF2, Local0)
-           And (Local0, One, Local0)
+           And (Local0, 0x03, Local0)
            Store (Local0, ^^H_EC.KLPC)
        }

Avoid erroring out on initialization and messing things up on cleanup
for now since we never call into these methods with anything different
than 1 or 0.

Instead when hw-blocked always write 1 to the blocked bit for the radio in

This is necessary for 3 reasons:
1) To apply sw_state changes made while hw-blocked
2) To set all the blocked bits for hw-switch controlled radios to 1 when the
   switch gets changed to off, this is necessary on some models to actually
   turn the radio status LEDs off.
3) On some models non hw-switch controlled radios will have their block bit
   cleared (potentially undoing a soft-block) on hw-switch toggle, this
   restores the sw-block in this case.

On machines with a hardware switch, the blocking settings can not be changed
through a Fn + wireless-key combo, so there is no reason to read back the
blocking state from the BIOS.

Reading back is not only not necessary it is actually harmful, since on some
machines the blocking state will be cleared to all 0 after a wireless switch
toggle, even for radios not controlled by the hw-switch (yeah firmware bugs).

This causes "magic" changes to the sw_state. This is inconsistent with other
rfkill drivers which preserve the sw_state over a hw kill on / off.

The query callback should only update the hw_state, see the comment in

rfkill_set_block will modify the sw_state directly after calling query so
calling set_sw_state is an expensive NOP.

The rfkill functionality was removed from the dell-laptop driver because it
was causing problems on various non Latitude models, and the blacklist kept
growing and growing. In the thread discussing this Dell mentioned that they
only QA the rfkill acpi interface on Latitudes and indeed there have been
no blacklist entries for Latitudes.

Note that the blacklist contained no Vostros either, and most Vostros have
a hardware switch too, so we could consider supporting Vostros with a

Without rfkill functionality in dell-laptop I have the following problems:
-If the hardware radio switch is set to disable the radio, then userspace
 will still think it can use wireless and bluetooth.
-The wwan / 3g modem cannot be soft blocked without the dell-laptop rfkill
 functionality

I know the rfkill functionality was removed from the dell-laptop driver because
it caused more problems then it fixed, and the blacklist for it was growing out
of control.

But in the thread discussing this Dell mentioned that they only QA the rfkill
acpi interface on Latitudes and indeed there have been no blacklist entries
for Latitudes. Therefor I would like to bring the rfkill functionality back
only for Latitudes. This patch is a straight-forward revert. The next patch
in this set will drop the blacklist and replace it with a Latitude check.

Pull powerpc LE updates from Ben Herrenschmidt:
 "With my previous pull request I mentioned some remaining Little Endian
  patches, notably support for our new ABI, which I was sitting on
  making sure it was all finalized.

  The toolchain folks confirmed it now, the new ABI is stable and merged
  with gcc, so we are all good.  Oh and we actually missed the actual
  Kconfig switch for LE so here it is, along with a couple more bug
  fixes.

  I have more fixes but not related to LE so I'll send them as a
  separate pull request tomorrow, let's get this one out of the way.

  Note that this supports running user space binaries using the new ABI,
  but the kernel itself still needs to be built with the old one.  We'll
  bring fixes for that after -rc1.

  Here's Anton log that goes with this series:

     This patch series adds support for the new ABI, LPAR support for
     H_SET_MODE and finally adds a kconfig option and defconfig.

     ABIv2 support was recently committed to binutils and gcc, and should
     be merged into glibc soon.  There are a number of very nice
     improvements including the removal of function descriptors.  Rusty's
     kernel patches allow binaries of either ABI to work, easing the
     transition"

This reverts commit ea1e7ed3.

Al points out that while the commit *does* actually create a separate
slab for the page->ptl allocation, that slab is never actually used, and
the code continues to use kmalloc/kfree.

Damien Wyart points out that the original patch did have the conversion
to use kmem_cache_alloc/free, so it got lost somewhere on its way to me.

Revert the half-arsed attempt that didn't do anything.  If we really do
want the special slab (remember: this is all relevant just for debug
builds, so it's not necessarily all that critical) we might as well redo
the patch fully.

I've finally tracked down why my CR signal-unwind test case still
fails on little-endian.  The problem turned to be that the kernel
installs a signal trampoline in the vDSO, and provides a DWARF CFI
record for that trampoline.  This CFI describes the save location
for CR:

  rsave (70, 38*RSIZE + (RSIZE - CRSIZE))

which is correct for big-endian, but points to the wrong word on
little-endian.   This is wrong no matter which ABI.

In addition, for the ELFv2 ABI, we should not only provide a CFI
record for register 70 (cr2), but for all CR fields separately.
Strictly speaking, I guess this would mean providing two separate
vDSO images, one for ELFv1 processes and one for ELFv2 processes (or
maybe playing some tricks with conditional DWARF expressions).
However, having CFI records for the other CR fields in ELFv1 is not
actually wrong, they just will be ignored.   So it seems the simplest
fix would be just to always provide CFI for all the fields.

Little endian ppc64 is getting an exciting new ABI.  This is reflected
by the bottom two bits of e_flags in the ELF header:

	0 == legacy binaries (v1 ABI)
	1 == binaries using the old ABI (compiled with a new toolchain)
	2 == binaries using the new ABI.

We store this in a thread flag, because we need to set it in core
