If CONFIG_SERIAL_8250_NR_UARTS is smaller than the array size in asm/serial.h, we trampled on memory which wasn't ours. Take our big boots away by limiting the number of ports initialised to the smaller of ...NR_UARTS and the array size. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The following patch enables attrs by default if the reiserfs_attrs_cleared bit is set in the superblock. This allows chattr-type attrs to be used without any further action by the user. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

ReiserFS currently will allow the user to set/get attrs for files regardless if they are enabled. The patch checks to see if they are enabled, and returns -NOTTY if they are not. ext[23] doesn't need this check because attrs are always enabled.

Patch from Tony Lindgren This patch adds support for Dynamic Tick Timer for OMAP. This patch is an updated version of ARM patch 2642/1 to make it work with the already integrated generic ARM dyntick support.

Remove legacy ISA serial ports for Accent, Boca, Fourport, Hub6 and MCA from the architecture specific serial.h include. The only ports which remain in asm-*/serial.h are the platform specific entries. These should really be converted by platform maintainers to use a platform device, such as can be found in arch/arm/mach-footbridge/isa.c Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Disable the transmitter whenever we want to prevent characters being transmitted by flow control. However, if we run out of characters to send and want to only disable the TX interrupt, allow that scenario. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Patch from Nicolas Pitre Those are big, slow and generally not recommended for kernel code. They are even not present on i386. So it should be concluded that one could as well get away with do_div() alone. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

I am using the atxp1 module to change vcore on my NForce2 via userspace daemon (see punnoor.de). Currently the atxp1 module will write to the log on every vcore change, thus filling up my log - which I don't want. I am no kernel coder, but I guess, this one-liner will change this behaviour in a wanted way, ie output will be made for debug purposes only.

Patch from Catalin Marinas The compiler allocates r14 for the stk variable in the __asm__ directive. This is a shadowed register and gets changed when the mode is changed, causing random values in the SP register. The patch adds a clobber for the r14 register.

Convert ARMs timer implementations to use readl/writel instead of accessing the registers via a struct. People have recently asked if accessing timers via a structure is the "right way" and its not the Linux way. So fix this code to conform to "The Linux Way"(tm).

Patch from Ben Dooks All current S3C24XX implementations from Simtec share the same requirements for suspend/resume information.

Useful to correct a bad color balance. - full_luma_range : provide a better contrast in using the full range 0-253 of values instead of 16-253. - coring : to have a better black level. - radio range is now defined on tuner-core.c.

Anyone reporting a stuck IRQ should try these options. Its effectiveness varies we've found in the Fedora case. Quite a few systems with misdescribed IRQ routing just work when you use irqpoll. It also fixes up the VIA systems although thats now fixed with the VIA quirk (which we could just make default as its what Redmond OS does but Linus didn't like it historically). A small number of systems have jammed IRQ sources or misdescribes that cause an IRQ that we have no handler registered anywhere for. In those cases it doesn't help.

Currently in ext3 block reservation code, the global filesystem reservation tree lock (rsv_block) is hold during the process of searching for a space to make a new reservation window, including while scaning the block bitmap to verify if the avalible window has a free block. Holding the lock during bitmap scan is unnecessary and could possibly cause scalability issue and latency issues. This patch tries to address this by dropping the lock before scan the bitmap. Before that we need to reserve the open window in case someone else is targetting at the same window. Question was should we reserve the whole free reservable space or just the window size we need. Reserve the whole free reservable space will possibly force other threads which intended to do block allocation nearby move to another block group(cause bad layout). In this patch, we just reserve the desired size before drop the lock and scan the block bitmap. This patch fixed a ext3 reservation latency issue seen on a cvs check out test. Patch is tested with many fsx, tiobench, dbench and untar a kernel test.
