2006-01-18[PATCH] uml: move headers to arch/um/includeGennady Sharapov
The serial UML OS-abstraction layer patch (um/kernel dir). This moves skas headers to arch/um/include.

2006-01-18[PATCH] uml: change interface to boot_timer_handlerBodo Stroesser
Current implementation of boot_timer_handler isn't usable for s390. So I changed its name to do_boot_timer_handler, taking (struct sigcontext *)sc as argument. do_boot_timer_handler is called from new boot_timer_handler() in arch/um/os-Linux/signal.c, which uses the same mechanisms as other signal handler to find out sigcontext pointer.

2006-01-18[PATCH] uml: move LDT creationBodo Stroesser
s390 doesn't have a LDT. So MM_COPY_SEGMENTS will not be supported on s390. The only user of MM_COPY_SEGMENTS is new_mm(), but that's no longer useful, as arch/sys-i386/ldt.c defines init_new_ldt(), which is called immediately after new_mm(). So we should copy host's LDT in init_new_ldt(), if /proc/mm is available, to have this subarch specific call in subarch code.

2006-01-17[SPARC64]: Eliminate race condition reading Hummingbird STICK registerRichard Mortimer
Ensure a consistent value is read from the STICK register by ensuring that both high and low are read without high changing due to a roll over of the low register. Various Debian/SPARC users (myself include) have noticed problems with Hummingbird based systems. The symptoms are that the system time is seen to jump forward 3 days, 6 hours, 11 minutes give or take a few seconds. In many cases the system then hangs some time afterwards. I've spotted a race condition in the code to read the STICK register. I could not work out why 3d, 6h, 11m is important but guess that it is due to the 2^32 jump of STICK (forwards on one read and then the next read will seem to be backwards) during a timer interrupt. I'm guessing that a change of -2^32 will get converted to a large unsigned increment after the arithmetic manipulation between STICK, nanoseconds, jiffies etc. I did a test where I modified __hbird_read_stick to artificially inject rollover faults forcefully every few seconds. With this I saw the clock jump over 6 times in 12 hours compared to once every month or so. Signed-off-by: Richard Mortimer <richm@oldelvet.org.uk> Signed-off-by: David S.

2006-01-16[PATCH] x86_64: Flexmap for 32bit and randomized mappings for 64bitAndi Kleen
Another try at this. For 32bit follow the 32bit implementation from Ingo - mappings are growing down from the end of stack now and vary randomly by 1GB. Randomized mappings for 64bit just vary the normal mmap break by 1TB. I didn't bother implementing full flex mmap for 64bit because it shouldn't be needed there.

2006-01-16[PATCH] sh: Move CPU subtype configuration to its own KconfigPaul Mundt
Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat. Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things like cache configuration are also moved to this new location. This also adds support for strict CPU tuning on newer cores, which requires the addition of as-option.

2006-01-16[PATCH] sh: Simplistic clock frameworkPaul Mundt
This adds a relatively simplistic clock framework for sh. The initial goal behind this is to clean up the arch/sh/kernel/time.c mess and to get the CPU subtype-specific frequency setting and calculation code moved somewhere more sensible. This only deals with the core clocks at the moment, though it's trivial for other drivers to define their own clocks as desired.

2006-01-16[PATCH] sh: I/O routine cleanups and ioremap() overhaulPaul Mundt
This introduces a few changes in the way that the I/O routines are defined on SH, specifically so that things like the iomap API properly wrap through the machvec for board-specific quirks. In addition to this, the old p3_ioremap() work is converted to a more generic __ioremap() that will map through the PMB if it's available, or fall back on page tables for everything else. An alpha-like IO_CONCAT is also added so we can start to clean up the board-specific io.h mess, which will be handled in board update patches..

2006-01-16[PATCH] sh: IRQ handler updatesPaul Mundt
This moves the various IRQ controller drivers into a new subdirectory, and also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780 interrupts, rather than just ST-40. The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as new ports are expected to be based off of CONFIG_SH_UNKNOWN. Since there are plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.

2006-01-16[PATCH] sh: DMA updatesPaul Mundt
This extends the current SH DMA API somewhat to support a proper virtual channel abstraction, and also works to represent this through the driver model by giving each DMAC its own platform device.

2006-01-16[PATCH] sh: consolidate hp620/hp680/hp690 targets into hp6xxPaul Mundt
