Add __meminit to the __init lineup to ensure functions default to __init when memory hotplug is not enabled. Replace __devinit with __meminit on functions that were changed when the memory hotplug code was introduced. Signed-off-by:

Add x86-64 specific memory hot-add functions, Kconfig options, and runtime kernel page table update functions to make hot-add usable on x86-64 machines. Also, fixup the nefarious conditional locking and exports pointed out by Andi. Tested on Intel and IBM x86-64 memory hot-add capable systems. Signed-off-by:

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. Cc: mingo@elte.hu Signed-off-by:

... as they are no longer needed. Since there were hard-coded numbers in the file, the patch also adds a mechanism to avoid these (otherwise potential future changes would again and again require adjusting these numbers). Signed-Off-By:

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. Signed-off-by:

As of 2.6.15 you need to use "anticipatory" instead of "as". Fix that up so that `elevator=as' still works. Signed-off-by:

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. Signed-off-by:

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). Signed-off-by:

Add a separate function for filling in the READ request. This will make it possible to send asynchronous READ requests as well as synchronous ones. Signed-off-by:

Now the INIT requests can be completely handled in inode.c and the fuse_send_init() function need not be global any more. Signed-off-by:

Add possibility for requests to run asynchronously and call an 'end' callback when finished. With this, the special handling of the INIT and RELEASE requests can be cleaned up too. Signed-off-by:

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. Signed-off-by:

Miklos Szeredi authored
This patch adds the 'waiting' attribute which indicates how many filesystem requests are currently waiting to be completed. A non-zero value without any filesystem activity indicates a hung or deadlocked filesystem. Signed-off-by:

Kobjectify fuse_conn, and make it visible under /sys/fs/fuse/connections. Lacking any natural naming, connections are numbered. This patch doesn't add any attributes, just the infrastructure. Signed-off-by:

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. Signed-off-by:

The state of request was made up of 2 bitfields (->sent and ->finished) and of the fact that the request was on a list or not. Unify this into a single state field. Signed-off-by:

This function used the request object after decrementing its reference count and releasing the lock. This could in theory lead to all sorts of problems. Fix and simplify at the same time. Signed-off-by:

The Rio Karma portable MP3 player has its own proprietary partition table. The partition layout is similar to a DOS boot sector but it begins at a different offset and uses a different magic number (0xAB56 instead of 0xAA55). Add support for it to enable mounting the device. Signed-off-by:

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. Signed-off-by:

Paul Mundt authored
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. Signed-off-by:

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.. Signed-off-by:

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. Signed-off-by:

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. There's also a few other minor changes to support a few new CPU subtypes, and make TEI generation for the SH DMAC configurable. Signed-off-by:

Most of the reasons for keeping these separate before was due to hp690 discontig, and since we have a workaround for that now (abusing some shadow space so everything is magically contiguous), there's no reason to keep the targets separate. Signed-off-by:
