2008-03-04md: clean up irregularity with raid autodetectNeilBrown
When a raid1 array is stopped, all components currently get added to the list for auto-detection. However we should really only add components that were found by autodetection in the first place. So add a flag to record that information, and use it.

2008-03-04md: reduce CPU wastage on idle md array with a write-intent bitmapNeilBrown
On an md array with a write-intent bitmap, a thread wakes up every few seconds and scans the bitmap looking for work to do. If the array is idle, there will be no work to do, but a lot of scanning is done to discover this. So cache the fact that the bitmap is completely clean, and avoid scanning the whole bitmap when the cache is known to be clean.

2008-03-04iommu: export iommu_is_span_boundary helper functionFUJITA Tomonori
iommu_is_span_boundary is used internally in the IOMMU helper (lib/iommu-helper.c), a primitive function that judges whether a memory area spans LLD's segment boundary or not. It's difficult to convert some IOMMUs to use the IOMMU helper but iommu_is_span_boundary is still useful for them. So this patch exports it. This is needed for the parisc iommu fixes.

2008-03-04memcg: remove mem_cgroup_unchargeHugh Dickins
Nothing uses mem_cgroup_uncharge apart from mem_cgroup_uncharge_page, (a trivial wrapper around it) and mem_cgroup_end_migration (which does the same as mem_cgroup_uncharge_page). And it often ends up having to lock just to let its caller unlock. Remove it (but leave the silly locking until a later patch). Moved mem_cgroup_cache_charge next to mem_cgroup_charge in memcontrol.h.

2008-03-04memcg: bad page if page_cgroup when freeHugh Dickins
Replace free_hot_cold_page's VM_BUG_ON(page_get_page_cgroup(page)) by a "Bad page state" and clear: most users don't have CONFIG_DEBUG_VM on, and if it were set here, it'd likely cause corruption when the page is reused. Don't use page_assign_page_cgroup to clear it: that should be private to memcontrol.c, and always called with the lock taken; and memmap_init_zone doesn't need it either - like page->mapping and other pointers throughout the kernel, Linux assumes pointers in zeroed structures are NULL pointers. Instead use page_reset_bad_cgroup, added to memcontrol.h for this only.

2008-03-04ndelay(): switch to C function to avoid 64-bit divisionAndrew Morton
We should be able to do ndelay(some_u64), but that can cause a call to __divdi3() to be emitted because the ndelay() macros does a divide. Fix it by switching to static inline which will force the u64 arg to be treated as an unsigned long. udelay() takes an unsigned long arg.

Add a <linux/gpio.h> defining fail/warn stubs for GPIO calls on platforms that don't support the GPIO programming interface. That includes the arch-specific implementation glue otherwise. This facilitates a new model for GPIO usage: drivers that can use GPIOs if they're available, but don't require them. One example of such a driver is NAND driver for various FreeScale chips. On platforms update with GPIO support, they can be used instead of a worst-case delay to verify that the BUSY signal is off. (Also includes a couple minor unrelated doc updates.)

2008-03-04PCI: Add DECLARE_PCI_DEVICE_TABLE macroJonas Bonn
The definitions of struct pci_device_id arrays should generally follow the same pattern across the entire kernel. This macro defines this array as const and puts it into the __devinitconst section. There are currently many definitions scattered about the kernel that omit the __devinitdata modifier despite the documentation stating that it should always be there. These definitions really also should have been const, which wasn't possible before but has become so with the addition of the __devinitconst attribute. Furthermore, there are definitions that use "const" and __devinitdata, which is explicitly wrong but the compiler doesn't catch section mismatches if there's only one such one case in the module (which is often the case). Adding the __devinitconst modifier where there was nothing before buys us memory. Adding the const modifier gives the compiler a chance to do its thing. Changing __devinitdata to __devinitconst where it was wrong actually fixes some compiler errors in older (mid-release) kernels that were patched over by "removing" the section attribute altogether (which wastes memory). This macro makes it pretty difficult to get this definition wrong in the future... Signed-off-by: Jonas Bonn <jonas@southpole.se> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This patch restores the meaning of rq->data_len to the true data length and adds rq->extra_len to store an extended length (due to drain buffer and padding). This patch also removes the code to update bio in blk_rq_map_user introduced by the commit 40b01b9bbdf51ae543a04744283bf2d56c4a6afa. The commit adjusts bio according to memory alignment (queue_dma_alignment). However, memory alignment is NOT padding alignment. This adjustment also breaks SG_IO friends and bsg.

2008-02-25lockdep: increase MAX_LOCK_DEPTHPeter Zijlstra
Some code paths exceed the current max lock depth (XFS), so increase this limit a bit. I looked at making this a dynamic allocated array, but we should not advocate insane lock depths, so stay with this as long as it works...

2008-02-24libata: automatically use DMADIR if drive/bridge requires itTejun Heo
Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir. That's nice, but most SATA devices which need it will tell us about it in their IDENTIFY PACKET response, as bit-15 of word-62 of the returned data (as per ATA7, ATA8 specifications). So for those which specify it, we should automatically use the DMADIR bit. Otherwise, disc writing will fail by default on many SATA-ATAPI drives. This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it if atapi_dmadir is set or identify data indicates DMADIR is necessary. atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting DMADIR. Original patch is from Mark Lord. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
