On x86_64, <asm/ptrace.h> uses __user but doesn't include <linux/compiler.h>. This could lead to build failures. Signed-off-by:

Fix a bug introduced with the CLFLUSH changes: we must always flush pages changed in cpa(), not just when they are reverted. Reenable CLFLUSH usage with that now (it was temporarily disabled for .22) Add some BUG_ONs Contains fixes from Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Signed-off-by:

Fixes STN LCD support for the atmel_lcdfb framebuffer driver. This patch is the result of a work from Jan Altenberg and has been tested on a Hitachi SP06Q002 on at91sam9261ek. It adds a Kconfig switch that enables the proper LCD in the board configuration file (STN or TFT). The switch is used in arch/arm/mach-at91/at91sam9261_devices.c & board-sam9261ek.c as an example. This patch includes the "Fix wrong line_length calculation" little one from Jan and Haavard (submitted earlier). AT91 platform informations are directly submitted trough the at91 maintainer, here : http://article.gmane.org/gmane.linux.kernel/543158Signed-off-by:

This patch adds support for the Simtek STK17TA8 timekeeping chip. The STK17TA8 is quite similar to the DS1553, but differs in register layout and in various control bits in the registers. I chose to make this a new driver to avoid confusion in the code and to not get lost in #ifdefs. Signed-off-by:

We now read and write the century byte in the max6900 chip. We probably don't need to do so on Linux-only system, but it's necessary when the chip is shared by another OS that uses the century byte. Signed-off-by:

Various people have expressed surprise that their modular RTC drivers don't seem to work for initializing the system time at boot. To help avoid such unpleasantness, make the Kconfig text point out that the driver probably needs to be statically linked. Signed-off-by:

The version of SLOB in -mm always scans its free list from the beginning, which results in small allocations and free segments clustering at the beginning of the list over time. This causes the average search to scan over a large stretch at the beginning on each allocation. By starting each page search where the last one left off, we evenly distribute the allocations and greatly shorten the average search. Without this patch, kernel compiles on a 1.5G machine take a large amount of system time for list scanning. With this patch, compiles are within a few seconds of performance of a SLAB kernel with no notable change in system time. Signed-off-by:

After discussing w/ Thomas over IRC, it seems the issue is the sched tick fires on every cpu at the same time, causing extra lock contention. This smaller change, adds an extra offset per cpu so the ticks don't line up. This patch also drops the idle latency from 40us down to under 20us. Signed-off-by:

We need to make sure, that the clockevent devices are resumed, before the tick is resumed. The current resume logic does not guarantee this. Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock event devices before resuming the tick / oneshot functionality. Fixup the existing users.
