2006-01-16[PATCH] x86_64: Fix VSMP buildRavikiran G Thirumalai
Patch fixes a build problem with CONFIG_X86_VSMP. The vSMP bits probably gathered some fuzz on its way to mainline, and safe_halt() which was outside the #endif (CONFIG_X86_VSMP) somehow got inside the !CONFIG_X86_VSMP condition, hence being undefined and breaking CONFIG_X86_VSMP builds. Patch takes safe_halt() and halt() macros out of the #endif Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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] md: Clear clevel whenever level is set.NeilBrown
The 'level' of an md array can be set as either a number of a string. When one is set, the other must be marked 'undefined'. This wasn't being done in one place: where new arrays are created. Result: if md1 is a raid1, it is stopped and a raid5 is created there, it might still appear to be a raid1.

2006-01-16[PATCH] fuse: fix bitfield raceMiklos Szeredi
Fix race in setting bitfields of fuse_conn. Spotted by Andrew Morton. The two fields ->connected and ->mounted were always changed with the fuse_lock held. But other bitfields in the same structure were changed without the lock. In theory this could lead to losing the assignment of even the ones under lock. The chosen solution is to change these two fields to be a full unsigned type. The other bitfields aren't "important" enough to warrant the extra complexity of full locking or changing them to bitops. For all bitfields document why they are safe wrt. concurrent assignments. Also make the initialization of the 'num_waiting' atomic counter explicit.

2006-01-16[PATCH] fuse: use asynchronous READ requests for readpagesMiklos Szeredi
This patch changes fuse_readpages() to send READ requests asynchronously. This makes it possible for userspace filesystems to utilize the kernel readahead logic instead of having to implement their own (resulting in double caching).

2006-01-16[PATCH] fuse: add connection abortingMiklos Szeredi
Add ability to abort a filesystem connection. With the introduction of asynchronous reads, the ability to interrupt any request is not enough to dissolve deadlocks, since now waiting for the request completion (page unlocked) is independent of the actual request, so in a deadlock all threads will be uninterruptible. The solution is to make it possible to abort all requests, even those currently undergoing I/O to/from userspace. The natural interface for this is 'mount -f mountpoint', but that only works as long as the filesystem is attached. So also add an 'abort' attribute to the sysfs view of the connection.

2006-01-16[PATCH] fuse: add number of waiting requests attributeMiklos Szeredi

2006-01-16[PATCH] fuse: extend semantics of connected flagMiklos Szeredi
The ->connected flag for a fuse_conn object previously only indicated whether the device file for this connection is currently open or not. Change it's meaning so that it indicates whether the connection is active or not: now either umount or device release will clear the flag. The separate ->mounted flag is still needed for handling background requests.

2006-01-16[PATCH] fuse: introduce unified request stateMiklos Szeredi

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.
