Commit ea0c62f7 tried to clear all bits in irq_stat but it didn't actually achieve that as irq_stat was anded with port_map right after read. This patch makes ahci driver always use the unmasked value to clear irq_status. While at it, add explanation on the peculiarities of ahci IRQ clearing. This was spotted by Linus Torvalds.

class->dev_release is called by device_release() iff dev->release is not present so ide_port_class_release() is never called and the last hwif->gendev reference is not dropped. Fix it by removing ide_port_class_release() and get_device() call from ide_register_port() (device_create_drvdata() takes a hwif->gendev reference anyway). This patch fixes hang on wait_for_completion(&hwif->gendev_rel_comp) in ide_unregister() reported by Pavel Machek. Cc: Pavel Machek <pavel@suse.cz> Cc: "Rafael J.

Some Dell laptops enter resume with apparent garbage in the segment descriptor registers (almost certainly the result of a botched transition from protected to real mode.) The only way to clean that up is to enter protected mode ourselves and clean out the descriptor registers. This fixes resume on Dell XPS M1210 and Dell D620.

Flags considered internal to the mempolicy kernel code are stored as part of the "flags" member of struct mempolicy.

The CaFe chip has a hardware bug that ends up with us getting a timeout value that's too small, causing the following sorts of problems: [ 60.525138] mmcblk0: error -110 transferring data [ 60.531477] end_request: I/O error, dev mmcblk0, sector 1484353 [ 60.533371] Buffer I/O error on device mmcblk0p2, logical block 181632 [ 60.533371] lost page write due to I/O error on mmcblk0p2 Presumably this is an off-by-one error in the hardware. Incrementing the timeout count value that we stuff into the TIMEOUT_CONTROL register gets us a value that works. This bug was originally discovered by Pierre Ossman, I believe.

This has been sitting around unloved for way too long.. The Marvell CaFe chip's SD implementation chokes during card insertion if one attempts to set the voltage and power up in the same SDHCI_POWER_CONTROL register write.

This patch changes the way we determine the maximum number of outstanding commands for each controller. Most Smart Array controllers can support up to 1024 commands, the notable exceptions are the E200 and E200i. The next generation of controllers which were just added support a mode of operation called Zero Memory Raid (ZMR). In this mode they only support 64 outstanding commands. In Full Function Raid (FFR) mode they support 1024. We have been setting the queue depth by arbitrarily assigning some value for each controller. We needed a better way to set the queue depth to avoid lots of annoying "fifo full" messages. So we made the driver a little smarter. We now read the config table and subtract 4 from the returned value. The -4 is to allow some room for ioctl calls which are not tracked the same way as io commands are tracked. Please consider this for inclusion.

The build of the Alpha Linux kernel currently fails[1] with inconsistent kallsyms data. As I never saw that before, I thought about hardware problems. But in fact it is a bug in the Linux kernel. The end of the rodata section is marked with the "__end_rodata" symbol. This symbol have different aligning constraints than the inittext parts and therefor the start marked "_sinittext". Because of that the __end_rodata symbol shifts between < _sinittext and == _sinittext. The later variant is seen as a code symbol and recorded in the kallsyms data. On fix would be to move the exception table a little bit and get some space between that two areas.

This got broken by the recent "fix rmmod $spi_driver while spidev-user is active". I tested the rmmod & write path but didn't check the read path. I am sorry. The read logic changed and spidev_sync_read() + spidev_sync_write() do not return zero on success anymore but the number of bytes that has been transfered over the bus. This patch changes the logic and copy_to_user() gets called again. The write path returns the number of bytes which are written to the underlying device what may be less than the requested size. This patch makes the same change to the read path or else we request a read of 20 bytes, get 10, don't call copy to user and report to the user that we read 10 bytes.

Starting last month, I reached a long-time goal: man-pages finally has a paid, full-time maintainer, thanks to a fellowship from the Linux Foundation. It's still a little unclear how long the LF money will last for the fellowship, but for the foreseeable future, I'll be working on: * Properly documenting every new Linux kernel-userland (and glibc) API, and every API change, that is released into the mainline kernel, ideally before actual release. (That's the ideal, but there's a quite a backlog, so I'm not going to achieve the ideal immediately.) * Testing new APIs, again ideally before they are released into the mainline kernel, and probably doing some light bug fixing while I'm at it (e.g., the recent utimensat() work). * Design review of new APIs, which of course can only usefully be done before they are released into the mainline kernel. * And of course accepting patches and dealing with bug reports for existing man pages.
