* [SPARC]: change if() BUG(); to BUG_ON in iommu.cEric Sesterhenn2006-01-171-7/+6
| | | | | | | | | this patch changes if() BUG(); constructs in iommu.c to BUG_ON(); so it gets save to define BUG() and BUG_ON() to nullstatements. Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Eliminate race condition reading Hummingbird STICK registerRichard Mortimer2006-01-171-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] x86_64: add __meminit for memory hotplugMatt Tolentino2006-01-161-1/+1
| | | | | | | | | | | Add __meminit to the __init lineup to ensure functions default to __init when memory hotplug is not enabled.

* [PATCH] x86_64: Flexmap for 32bit and randomized mappings for 64bitAndi Kleen2006-01-164-2/+111
| | | | | | | | | | | | | | | | | 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.

* [PATCH] sh: Move CPU subtype configuration to its own KconfigPaul Mundt2006-01-164-350/+482
| | | | | | | | | | | | | | 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.

* [PATCH] sh: Simplistic clock frameworkPaul Mundt2006-01-1616-612/+1224
| | | | | | | | | | | | | | | 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.

* [PATCH] sh: I/O routine cleanups and ioremap() overhaulPaul Mundt2006-01-163-136/+196
| | | | | | | | | | | | | | | | | 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..

* [PATCH] sh: IRQ handler updatesPaul Mundt2006-01-168-452/+536
| | | | | | | | | | | | | | 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.
