This patch adds a MMU dependency to configure the ZSMALLOC in
drivers/staging/zsmalloc/Kconfig. Without this patch, build
system can lead to build failure. This was observed during
randconfig testing, in which ZSMALLOC was enabled w/o MMU being

Alarm proc file provides the info and control of RTC-CMOS alarm and
RTC CMOS driver provides wakealarm sysfs attribute for the same
purpose. The alarm file isn't compiled into kernel when RTC CMOS
driver is selected. The driver is default to be selected for x86

SMC_outw invokes an endian-aware I/O accessor, which may change the data
endianness before writing to the device. This is not suitable for data
transfers where the memory buffer is simply a string of bytes that does
not require any byte-swapping.
This patches fixes the smc91x SMC_PUSH_DATA macro so that it uses the
string I/O accessor for outputting the leading or trailing halfwords on
halfword-aligned buffers.

The ip6_tnl.hlen (gre and ipv6 headers length) is independent from the
outgoing interface, so it would be better to initialize it even when no
route is found, otherwise its value will be zero.
While I'm not sure if this could happen in real life, but doing that
will avoid to call the skb_push function with a zero in ip6gre_header
function.

The old style frame counter increments at the start of active video.
However for i915_get_vblank_counter() we want a counter that increments
at the start of vblank.
Fortunately the low frame counter register also contains the pixel
counter for the current frame. We can can compare that against the
vblank start pixel count to determine if we need to increment the
frame counter by 1 to get the correct answer.
Also reorganize the function pointer assignments in intel_irq_init() a
bit to avoid confusing people.

Boots Just Fine (tm)!
The only glitch seems to be that at least on Fedora the boot splash
gets confused and doesn't display much at all.
And since there's no ugly console flickering anymore in between, the
flicker while switching between X servers (VT support is still enabled)
is even more jarring.
Also, I'm unsure whether we don't need to somehow kick out vgacon, now
that nothing else gets in the way. But stuff seems to work, so I
don't care. Also everything still works as well with VGA_CONSOLE=n
Also the #ifdef mess needs a bit of a cleanup, follow-up patches will
do just that.
To keep the Kconfig tidy, extract all the i915 options into its own
file.
v2:
- Rebase on top of the preliminary hw support option and the
intel_drv.h cleanup.
- Shut up warnings in i915_debugfs.c
v3: Use the right CONFIG variable, spotted by Chon Ming.

For drivers which might want to disable fbdev legacy support.
Select the new option in all drivers for now, so this shouldn't result
in any change. Drivers need some work anyway to make fbdev support
optional (if they have it implemented, that is), so the recommended
way to expose this is by adding per-driver options. At least as long
as most drivers don't support disabling the fbdev support.
v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm
driver can already take advantage of this, which allows us to build
msm without any fbdev depencies in the kernel!
v3: Move the MODULE_* stuff from the fbdev helper file to
drm_crtc_helper.c.

The spec says the default timeout should be 2ms, but on my machine
this doesn't seem to be enough. Sometimes it works, sometimes I get
these messages when booting:
- SWSCI request timed out
- SWSCI request already in progress
And my guess is that the "already in progress" message is because the
first one is still happening.
I did some experiments on my machine (that has CONFIG_HZ=1000) and the
wait_for function usually takes 4-6 jiffies to finish, but I've seen
up to 9. So increase the timeout to 50ms. We only expect to wait for
the actual amount of time the operation takes, so even a huge timeout
shouldn't delay us more than what the hardware actually requires.
