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.

Even the newer ENE controllers have bugs in their DMA engine that make it too dangerous to use. Disable it until someone has figured out under which conditions it corrupts data. This has caused problems at least once, and can be found as bug report 10925 in the kernel bugzilla. Signed-off-by:

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 adds a quirk that does that particular dance in two steps. It also adds an entry to pci_ids.h for the CaFe chip's SD device. Signed-off-by:

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. Signed-off-by:Mike Miller <mike.miller@hp.com> Cc: Jens Axboe...

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.

The filesystem capability support meaning for CAP_SETPCAP is less powerful than the non-filesystem capability support. As such, when filesystem capabilities are configured, we should not permit CAP_SETPCAP to 'enhance' the current process through strace manipulation of a child process. Signed-off-by:

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.

Commit 95b570c9 ("Taint kernel after WARN_ON(condition)") introduced a TAINT_WARN that was implemented for all architectures using the generic warn_on_slowpath(), which excluded any architecture that set HAVE_ARCH_WARN_ON. As all of the architectures that implement their own WARN_ON() all go through the report_bug() path (specifically handling BUG_TRAP_TYPE_WARN), taint the kernel there as well for consistency. Tested on avr32 and sh. Also relevant for s390, parisc, and powerpc. Signed-off-by:
