The root freezer_state is always CGROUP_THAWED so we can remove the special case from the code. The test itself can be handy and is extracted to static function. Signed-off-by:

When dirty_ratio or dirty_bytes is written the other parameter is disabled and set to 0 (in dirty_bytes_handler() / dirty_ratio_handler()). We do the same for dirty_background_ratio and dirty_background_bytes. However, in the sysctl documentation, we say that the counterpart becomes a function of the old value, that is not correct. Clarify the documentation reporting the actual behaviour. Reviewed-by:

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> @r exists@ local idexpression x; expression E; identifier f1; iterator I; @@ x = framebuffer_alloc(...); <... when != x when != true (x == NULL || ...) when != if (...) { <+...x...+> } when != I (...) { <+...x...+> } ( x == NULL | x == E | x->f1 ) ...> * return ...; // </smpl> Signed-off-by:

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. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // </smpl> Signed-off-by:

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). Signed-off-by:

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.

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).

Sekhar Nori authored
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.
