* efs: move headers out of include/linux/Christoph Hellwig2008-02-233-166/+0
| | | | | | | | | | | | | Merge include/linux/efs_fs{_i,_dir}.h into fs/efs/efs.h. efs_vh.h remains there because this is the IRIX volume header and shouldn't really be handled by efs but by the partitioning code. efs_sb.h remains there for now because it's exported to userspace. Of course this wrong and aboot should have a copy of it's own, but I'll leave that to a separate patch to avoid any contention.

* spi: pxa2xx_spi clock polarity fixNed Forrester2008-02-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a sequencing bug in spi driver pxa2xx_spi.c in which the chip select for a transfer may be asserted before the clock polarity is set on the interface. As a result of this bug, the clock signal may have the wrong polarity at transfer start, so it may need to make an extra half transition before the intended clock/data signals begin. (This probably means all transfers are one bit out of sequence.) This only occurs on the first transfer following a change in clock polarity in systems using more than one more than one such polarity. The fix assures that the clock mode is properly set before asserting chip select. This bug was introduced in a patch merged on 2006/12/10, kernel 2.6.20. The patch defines an additional bit in: include/asm-arm/arch-pxa/regs-ssp.h for 2.6.25 and newer kernels but this addition must be made in: include/asm-arm/arch-pxa/pxa-regs.h for kernels between 2.6.20 and 2.6.24, inclusive Signed-off-by: Ned Forrester <nforrester@whoi.edu> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Cc: Russell King <rmk@arm.linux.org.uk> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* sparc: fix buildDavid Rientjes2008-02-231-3/+0

Note that these includes are recent addition caused by added inline function that had since then become a define. So while I agree with your comments in general, in _this_ case it's pretty safe. The commit that had done it is 3062fc67dad01b1d2a15d58c709eff946389eca4 ("memcontrol: move mm_cgroup to header file") and the switch to #define is in commit 60c12b1202a60eabb1c61317e5d2678fcea9893f ("memcontrol: add vm_match_cgroup()") (BTW, that probably warranted mentioning in the changelog of the latter).

* percpu: fix DEBUG_PREEMPT per_cpu checkingHugh Dickins2008-02-232-1/+3
| | | | | | | | | | | | | | | | | 2.6.25-rc1 percpu changes broke CONFIG_DEBUG_PREEMPT's per_cpu checking on several architectures. On s390, sparc64 and x86 it's been weakened to not checking at all; whereas on powerpc64 it's become too strict, issuing warnings from __raw_get_cpu_var in io_schedule and init_timer for example. Fix this by weakening powerpc's __my_cpu_offset to use the non-checking local_paca instead of get_paca (which itself contains such a check); and strengthening the generic my_cpu_offset to go the old slow way via smp_processor_id when CONFIG_DEBUG_PREEMPT (debug_smp_processor_id is where all the knowledge of what's correct when lives).

* PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-231-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

And the asm-x86/desc_64.h file was supposed to be removed by commit c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around containing just a single newline.

| * | | [XTENSA] Allow debugger to modify the WINDOWBASE register.Chris Zankel2008-02-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the 'return' command, GDB needs to adjust WINDOWBASE. In case WB is different from 0, we need to rotate the window register file and update WINDOWSTART and WMASK. This patch also removes some ret|= statements for __get_user/__put_user as the address range was alrady checked a couple of lines earlier. Signed-off-by: Chris Zankel <chris@zankel.net>
| * | | [XTENSA] Fix cache flush macro for D$/I$ aliasing/non-aliasingChris Zankel2008-02-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For configurations that have aliasing in the data cache but not in the instruction cache, we don't need to flush the instruction cache. Thus, we didn't define the macros to flush the instruction cache. Some cache-flush functions, howerver, were using those macros. Signed-off-by: Chris Zankel <chris@zankel.net>

Registers that are bound to a coprocessor are only accessible if the corresponding enable bit is set, which allows to implement a 'lazy' context switch mechanism. Other registers needs to be saved and restore at the time of the context switch or during interrupt handling. This patch adds support for these additional states: - save and restore registers that are used by the compiler upon interrupt entry and exit. - context switch additional registers unbound to any coprocessor - 'lazy' context switch of registers bound to a coprocessor - ptrace interface to provide access to additional registers - update configuration files in include/asm-xtensa/variant-fsf Signed-off-by: Chris Zankel <chris@zankel.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove additional registers from the ELF gregset structure that are only used by the kernel or are not required or invalid in user-space. The ar registers are always aligned to a windowbase value of 0, and the WB register is always assumed to be 0. Increase the size of the structure to 128 entries. This will provide enough space in future. Signed-off-by: Chris Zankel <chris@zankel.net>

Because of this, a large amount of machinery grew up in ide to adjust scatterlists on this basis. However, as of 2.5, the block layer has a dma_alignment variable which ensures both the beginning and length of a DMA transfer are aligned on the dma_alignment boundary. Although the block layer does adjust the beginning of the transfer to ensure this happens, it doesn't actually adjust the length, it merely makes sure that space is allocated for transfers beyond the declared length. The upshot of this is that scatterlists may be padded to any size between the actual length and the length adjusted to the dma_alignment safely knowing that memory is allocated in this region. Right at the moment, SCSI takes the default dma_aligment which is on a 512 byte boundary. Note that this aligment only applies to transfers coming in from user space. However, since all kernel allocations are automatically aligned on a minimum of 32 byte boundaries, it is safe to adjust them in this manner as well. tj: * Adjusting sg after padding is done in block layer. Make libata set queue alignment correctly for ATAPI devices and drop broken sg mangling from ata_sg_setup(). * Use request->raw_data_len for ATAPI transfer chunk size. * Killed qc->raw_nbytes. * Separated out killing qc->n_iter.
