And this points out that the return value from isa_dev_get_resource() and the 'pregs' arg to isa_dev_get_irq() are totally unused. Based upon a patch from Richard Mortimer <richm@oldelvet.org.uk> Signed-off-by:David S. Miller <davem@davemloft.net>

We need to pass in the resource otherwise we cannot release the region properly. We must know whether it is an I/O or MEM resource. Spotted by Eric Brower. Signed-off-by: -

We were not being careful enough. When we trim the physical memory areas, we have to make sure we don't remove the kernel image or initial ramdisk image ranges. Signed-off-by:

fix an GFP_KERNEL allocation in atomic section: kvm_dev_ioctl_create_vcpu() called kvm_mmu_init(), which calls alloc_pages(), while holding the vcpu. The fix is to set up the MMU state in two phases: kvm_mmu_create() and kvm_mmu_setup(). (NOTE: free_vcpus does an kvm_mmu_destroy() call so there's no need for any extra teardown branch on allocation/init failure here.) Signed-off-by:

The latest version of kvm doesn't initialize kvm_arch_ops in kvm_init(), which causes an error with the following sequence. 1. Load the supported arch's module. 2. Load the unsupported arch's module.$B!!(B(loading error) 3. Unload the unsupported arch's module. You'll get the following error message after step 3. "BUG: unable to handle to handle kernel paging request at virtual address xxxxxxxx" The problem here is that the unsupported arch's module overwrites kvm_arch_ops of the supported arch's module at step 2. This patch initializes kvm_arch_ops upon loading architecture specific kvm module, and prevents overwriting kvm_arch_ops when kvm_arch_ops is already set correctly. 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:

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.
