If a CD has both Rock Ridge and Joliet extensions and the ISO root
directory is empty, no files are visible. Disable Rock Ridge extensions
in this case and use Joliet root directory instead.

This code is preceded by a call to framebuffer_alloc, which allocates
memory, so this memory should be freed before leaving the function in an
error case. out_release_framebuffer just frees the frame buffer and
returns.
A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)
// <smpl>

fb_{read,write} access the framebuffer using lots of fb_{read,write}l's
but don't check that the file position is aligned which can cause problems
on some architectures which do not support unaligned accesses.
Since the operations are essentially memcpy_{from,to}io, new
fb_memcpy_{from,to}fb macros have been defined and these are used instead.
For Sparc, fb_{read,write} macros use sbus_{read,write}, so this defines
new sbus_memcpy_{from,to}io functions the same as memcpy_{from,to}io but
using sbus_{read,write}b instead of {read,write}b.

The function has an unsigned return type, but returns a negative constant
to indicate an error condition. The result of calling the function is
only tested by comparison to 0, and thus unsigned is not needed and can be
dropped from the return type.

(http://coccinelle.lip6.fr/)
// <smpl>

I tested savagefb on 3 different Savage 4 cards:
Diamond Stealth III S520
Number Nine SR9
Datapath Horizon 2S (two savage chips on a PCI card)
it worked except the DDC which did not work on any of them.
Looking at the BIOS code, it does not use MMIO register 0xff20 but CRT
register 0xa0 or 0xb1 - depending on the chip revision and something in
register 0xa6. With this patch, DDC works fine on all 3 cards (even on
the second head of Horizon 2S - although it does not display anything as
it's misconfigured because of missing BIOS).

Topcliff PCH is the platform controller hub that is going to be used in
Intel's upcoming general embedded platform. All IO peripherals in
Topcliff PCH are actually devices sitting on AMBA bus. Topcliff PCH has
GPIO I/F. Using this I/F, it is able to access system devices connected
to GPIO.

The basic GPIO controllers may be found in various on-board FPGA and ASIC
solutions that are used to control board's switches, LEDs, chip-selects,
Ethernet/USB PHY power, etc.
These controllers may not provide any means of pin setup
(in/out/open drain).
The driver supports:
- 8/16/32/64 bits registers;
- GPIO controllers with clear/set registers;
- GPIO controllers with a single "data" register;
- Big endian bits/GPIOs ordering (mostly used on PowerPC).

The rtc-omap driver currently hardcodes the RTC wakeup capability to be
"not capable". While this seems to be true for existing OMAP1 boards
which are not wired for this, the DA850/OMAP-L138 SoC, the RTC can always
be wake up source from its "deep sleep" mode.
This patch lets the wakeup capability be set from platform data and does
not override the setting from the driver. For DA850/OMAP-L138, this is
done from arch/arm/mach-davinci/devices-da8xx.c:da8xx_register_rtc()
Note that this patch does not change the behavior on any existing OMAP1
board since the platform device registration sets the wakeup capability to
0 by default.

Christoph reported a nice splat which illustrated a race in the new stack
based kmap_atomic implementation.
The problem is that we pop our stack slot before we're completely done
resetting its state -- in particular clearing the PTE (sometimes that's
CONFIG_DEBUG_HIGHMEM). If an interrupt happens before we actually clear
the PTE used for the last slot, that interrupt can reuse the slot in a
dirty state, which triggers a BUG in kmap_atomic().
Fix this by introducing kmap_atomic_idx() which reports the current slot
index without actually releasing it and use that to find the PTE and delay
the _pop() until after we're completely done.
