Instead of doing tricky stuff with the arch dependent virtualization registers, take a peek at the guest's efer. This simlifies some code, and fixes some confusion in the mmu branch. Signed-off-by:

current_cpu_data invokes smp_processor_id(), which is inadvisable when preemption is enabled. Switch to boot_cpu_data instead. Resolves sourceforge bug 1621401. Signed-off-by:

The fallback to PIO mode in the hwif->dma_check() handler doesn't work in the Intel PIIX and SMsC SLC90E66 IDE drivers because: - config_drive_for_dma() calls the hwif->speedproc() handler with a wrong mode number (unbiased by XFER_PIO_0) in case of the PIO fallback; - hwif->tuneproc() handler doesn't really set the drive's own speed (this is not fixed as yet).

There's no need to check in piix_config_drive_for_dma() for broken MW DMA mode 0 as this mode is not supported by the driver (it sets hwif->mwdma_mask to 0x6), and hence can't be selected by ide_dma_speed(). (Alan sayeth "Probably right but if not you've got a subtle corruptor. Should at least stick a BUG_ON mode 0 setting right close when the mode is set.") Signed-off-by:

Russel King recently reminded us that one shouldn't use asm/arch/hardware.h but one should use asm/hardware.h. Unfortunately, the spi_s3c24xx_gpio driver is using the wrong header. This patch is fixing that. Signed-off-by:

David Brownell authored
Some issues were recently turned up with the current specification of what it means for spi_transfer.tx_buf to be null, as part of transfers which are (from the SPI protocol driver perspective) pure reads. Specifically, that it seems better to change the TX behaviour there from "undefined" to "will shift zeroes". This lets protocol drivers (like the ads7846 driver) depend on that behavior. It's what most controller drivers in the tree are already doing (with one exception and one case of driver wanting-to-oops), it's what Microwire hardware will necessarily be doing, and it removes an issue whereby certain security audits would need to define such a value anyway as part of removing covert channels. This patch changes the specification to require shifting zeroes, and updates all currently merged SPI controller drivers to do so. Signed-off-by:

Recent cleanup of slab.h broke SLOB allocator: the routine kmem_cache_init has now the __init attribute for both slab.c and slob.c. This routine cannot be removed after init in the case of slob.c -- it serves as a timer callback. Provide a separate timer callback routine, call it once from kmem_cache_init, keep the __init attribute on the latter. Signed-off-by:

Remove the __resched_legal() check: it is conceptually broken. The biggest problem it had is that it can mask buggy cond_resched() calls. A cond_resched() call is only legal if we are not in an atomic context, with two narrow exceptions: - if the system is booting - a reacquire_kernel_lock() down() done while PREEMPT_ACTIVE is set But __resched_legal() hid this and just silently returned whenever these primitives were called from invalid contexts. (Same goes for cond_resched_locked() and cond_resched_softirq()). Furthermore, the __legal_resched(0) call was buggy in that it caused unnecessarily long softirq latencies via cond_resched_softirq(). (which is only called from softirq-off sections, hence the code did nothing.) The fix is to resurrect the efficiency of the might_sleep checks and to only allow the narrow exceptions. Signed-off-by:

include/linux/utsrelease.h and include/linux/version.h aren't removed any more by mrproper in kernel 2.6.20-rc2. The patch below fixes this. The definition of MRPROPER_FILES looks weird: generated-headers looks like a misspelling of generated_headers, but that one is a Makefile target, not a variable or a file, so I don't see how including it in MRPROPER_FILES could have any effect.

constrained_alloc(), which is called to detect where oom is from, checks passed zone_list(). If zone_list doesn't include all nodes, it thinks oom is from mempolicy. But there is memory-less-node. memory-less-node's zones are never included in zonelist[]. contstrained_alloc() should get memory_less_node into count. Otherwise, it always thinks 'oom is from mempolicy'. This means that current process dies at any time. This patch fix it. Signed-off-by:

WARN_ON() ever triggering is a kernel bug. Do not try to paper over this fact by suggesting to the user that this is 'only' a warning, as the following recent commit does: commit 30e25b71 Author: Jeremy Fitzhardinge <jeremy@goop.org> Date: Fri Dec 8 02:36:24 2006 -0800 [PATCH] Fix generic WARN_ON message A warning is a warning, not a BUG. ( it might make sense to rename BUG() to CRASH() and BUG_ON() to CRASH_ON(), but that does not change the fact that WARN_ON() signals a kernel bug. ) i and others objected to this change during lkml review: http://marc.theaimsgroup.com/?l=linux-kernel&m=116115160710533&w=2 still the change slipped upstream - grumble :) Also, use the standard "BUG: " format to make it easier to grep logs and to make it easier to google for kernel bugs.

lockdep found a AB BC CA lock inversion in retry-based AIO: 1) The task struct's alloc_lock (A) is acquired in process context with interrupts enabled. An interrupt might arrive and call wake_up() which grabs the wait queue's q->lock (B). 2) When performing retry-based AIO the AIO core registers aio_wake_function() as the wake funtion for iocb->ki_wait. It is called with the wait queue's q->lock (B) held and then tries to add the iocb to the run list after acquiring the ctx_lock (C). 3) aio_kick_handler() holds the ctx_lock (C) while acquiring the alloc_lock (A) via lock_task() and unuse_mm(). Lockdep emits a warning saying that we're trying to connect the irq-safe q->lock to the irq-unsafe alloc_lock via ctx_lock. This fixes the inversion by calling unuse_mm() in the AIO kick handing path after we've released the ctx_lock. As Ben LaHaise pointed out __put_ioctx could set ctx->mm to NULL, so we must only access ctx->mm while we have the lock. Signed-off-by:
