Reduce substantially the amount of code using PF_MEMALLOC, as envisaged in the original FIXME. If you're using lvm2, for this patch to work correctly you should update to lvm2 version 2.02.01 or later and device-mapper version 1.02.02 or later. Signed-off-by:

Clean up the code responsible for the on-disk mirror logs by using the set_le_bit test_le_bit functions of ext2. That makes the BE machines keep the bitmap internally in LE order - it does mean you can't use any other type of operations on the bitmap words but that looks to be OK in this instance. The efficiency tradeoff is very minimal as you would expect for something that ext2 uses. This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits. Also increment the mirror log disk version transparently to avoid sharing with older kernels that suffered from the 64-bit BE bug. Signed-off-by:

Move snapshot metadata loading to happen when the table is created instead of when the device is resumed. Writes to the origin device don't trigger exceptions until each snapshot table becomes active when resume() is called on each snapshot. If you're using lvm2, for this patch to work properly you should update to lvm2 version 2.02.01 or later and device-mapper version 1.02.02 or later. Signed-off-by:

Make the platform function interrupt functions actually work. Calls irq_enable() for the first in the list, and irq_disable() for the last. Added *func to struct irq_client so the the user can pass just that to pmf_unregister_irq_client(). Signed-off-by:

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to find any devices to bind to. It also triggers a message "Driver 'ide-scsi' needs updating - please use bus_type methods" from the driver core. The IDE core in 2.6.16-rc1 changed the location of an IDE driver's ->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t struct not in the gen_driver sub-struct. drivers/ide/ was updated for this change but ide-scsi.c wasn't. Hence the breakage. This patch repairs ide-scsi and also eliminates the driver core warning. Signed-off-by:

In 2.6.16-rc1 there is a small typo introduced by the 'Remove device_node addrs/n_addr' changes which prevents my Powerbook G4 sound from working: Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC). snd: can't request rsrc 0 (Sound Control: 0x80000000:80004fff) ALSA device list: No soundcards found. The patch below fixes it. Of course, the patch fixing the i2c issues ('i2c_smbus_write_i2c_block_data' patch) needs to be applied to in order for the sound to completly work.

While asynchronous reads mean a performance improvement in most cases, if the filesystem assumed that reads are synchronous, then async reads may degrade performance (filesystem may receive reads out of order, which can confuse it's own readahead logic). With sshfs a 1.5 to 4 times slowdown can be measured. There's also a need for userspace filesystems to know whether asynchronous reads are supported by the kernel or not. To achive these, negotiate in the INIT request whether async reads will be used and the maximum readahead value. Update interface version to 7.6 If userspace uses a version earlier than 7.6, then disable async reads, and set maximum readahead value to the maximum read size, as done in previous versions.

An old patch designed to fix http://bugme.osdl.org/show_bug.cgi?id=4497, "getdents gives empty/random result upon signal". If smbfs's readdir() is interupted by a signal, smb_readdir() failed to noticed that and proceeded to treat the unread-into page as valid directory contents. Fix that up by handling the -ERESTARTSYS. Thanks to Stian Skjelstad for reporting and testing. Cc: Stian Skjelstad <stian@nixia.no> Signed-off-by:

Older pSeries systems with serial ports dont get any console output after recent changes. CONFIG_ISA does not make sense for CONFIG_PPC_PSERIES because it enables lots of old drivers. Instead, remove the dependency on CONFIG_ISA from the serial port discovery code. Signed-off-by:

Error checking is scattered through various layers of the dlpar code, leading to a somewhat opaque code structure. This patch consolidates error checking in one routine, simplifying the code a tad. There's also some whitespace cleanup here too. Signed-off-by:

Keck, David authored
This patch fixes the AMD POGO errata on the hotplug controller where the platform will lock up or reboot if PERR/SERR generation is enabled and a slot is sent an enable command. This fix disables PERR/SERR generation before a slot is sent the enable command by first saving related registers, turning off SERR/PERR generation, enabling the slot, then restoring the registers.

Removing and then adding a PCI slot to a running partition results in a kernel panic. The current code attempts to add iospace for an entire root bus, which is inappropriate, and silently fails. When a pci device tries to use the iospace, a page fault is taken, as the iospace had not been mapped, and of course the page fault cannot be resolved. This only occurs for PCI adapters using pio, which may be why it hadn't been seen earlier (this seems to have been broken for a while). This patch has survived testing of dozens of slot add and removes. Signed-off-by:

The RPAPHP hoplug driver will not build as a module, because it calls on pci_claim_resource(), which is not exported. This exports the symbol.
