2007-11-08libata sata_qstor conversion to new error handling (EH).Mark Lord
sata_qstor conversion to new error handling (EH). Convert sata_qstor to use the newer libata EH mechanisms. Based on earlier work by Jeff Garzik. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-11-08libata sata_qstor workaround for spurious interruptsMark Lord
sata_qstor workaround for spurious interrupts. The qstor hardware generates spurious interrupts from time to time when switching in and out of packet mode. These eventually result in the IRQ being disabled, which kills other devices sharing this IRQ with us. This workaround isn't perfect, but it's about the best we can do for this hardware. Spurious interrupts will still happen, but won't be logged as such, and therefore won't cause the IRQ to be inadvertently disabled.

2007-11-08[CIFS] Fix incorrect mode when ACL had deny access control entriesSteve French
When mounted with the cifsacl mount option, we were treating any deny ACEs found like allow ACEs and it turns out for SFU and SUA Windows set these type of access control entries often. The order of ACEs is important too. The canonical order that most ACL tools and Windows explorer consruct ACLs with is to begin with DENY entries then follow with ALLOW, otherwise an allow entry could be encountered first, making the subsequent deny entry like "dead code which would be superflous since Windows stops when a match is made for the operation you are trying to perform for your user We start with no permissions in the mode and build up as we find permissions (ie allow ACEs). This fixes deny ACEs so they affect the mask used to set the subsequent allow ACEs.

2007-11-08hwmon: (applesmc) Add support for Mac Pro 2 x Quad-CoreRené Rebe
At least the 2x Quad-Core Apple Mac Pro appears to have some over-heat protection which suddenly powers off the whole box under load. This adds support for the fans and temerature sensors in the Mac Pro - later some "windwarm" a-like code should probably monitor the values. For now manually tweaking the fans prevents the sudden shutdown for me. cd /sys/devices/platform/applesmc.768 for x in fan{1,2,3,4}; do echo 1 > ${x}_manual echo 1285 > ${x}_output done Two sensors are 0, while four are 129 °C, those might be removed again, later.

2007-11-08hwmon: (w83627hf) hoist nr-1 offset out of show-store-temp-XJim Cromie
This hoists nr-1 offset out of (show|store)_temp_*(.*) callbacks, and into SENSOR_DEVICE_ATTRs for sysfs tempN_X files. It also combines temp[1] and temp_add[2] (array) fields in w83627hf_data into 3 elem arrays, which simplifies special-case handling of nr, allowing simplification of callback bodies and rerolling a flattened loop in w83627hf_update_device(struct device *dev). The array conversion changes temp[1] from u8 to u16, but this was happening implicitly via the helper functions anyway.

2007-11-08[ARM] 4644/2: fix flush_kern_tlb_range() in module spaceKevin Hilman
For kernel addresses between TASK_SIZE and PAGE_OFFSET, flush_tlb_kern_range() does not work as would be expected. The TLB invalidate works with a matching ASID, or on entries marked as global. The set_pte_at() macro marks addresses >= PAGE_OFFSET as global, but not addresses from TASK_SIZE to PAGE_OFFSET, which are also kernel addresses. The result is that the entries in this range are not actually invalidated by flush_tlb_kern_range(). This patch instead marks addresses >= TASK_SIZE as global.

2007-11-08[POWERPC] windfarm: Fix windfarm thread freezer interactionJohannes Berg
When I fixed the windfarm freezer interaction first in commit 1ed2ddf380e19dafeec2150ca709ef7f4a67cd21, an earlier patch than the one I came up with after comments was committed. This has come back to haunt us now because commit d5d8c5976d6adeddb8208c240460411e2198b393 changed the freezer to no long send signals. Fix it by removing the windfarm thread's signal logic and restoring the original try_to_freeze(). We could simply revert 1ed2ddf380e19dafeec2150ca709ef7f4a67cd21 now but I feel that the assertion that no signal is delivered to the windfarm thread needs not be there.
