Add checks to ensure that out-of-band reads and writes are not attempted with an invalid offset or length. Specifically, the offset must be less than the size of oob for a page and the length must not go beyond the size of the device. Additionally the checks must adjust for auto-placement (MTD_OOB_AUTO) of oob data. Signed-off-by: NAdrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: NDavid Woodhouse <dwmw2@infradead.org>

In commit c172471b Nico switched to using common code for polling for command completion. Unfortunately he also used a common default timeout for both write and erase commands, despite the fact that erases can take a _whole_ lot longer. Use a more sensible default for erase timeout.

OneNAND double-density package (DDP) has two chips, each with their own bufferRAM. The driver will skip loading data from the NAND core if the data can be found in a bufferRAM, however in that case, the correct chip's bufferRAM must be selected before reading from bufferRAM.

This patch fixes up ia64 kexec support for HP rx2620 hardware. It does this by skipping migration of already disabled irqs. This is most likely a problem on other ia64 platforms as well, but I've only been able to reproduce it on one machine so far. The full story is that handle_bad_irq() gets invoked before starting the new kernel without this patch. This seems to happen when fixup_irqs() calls generic_handle_irq() on already migrated (and disabled) irqs. So by avoiding migration of disabled irqs we stay away of handle_bad_irq(). The code has been tested on three different ia64 machines, all with good results. It is possible to trigger the same bug by offlining a processor using echo 0 > /sys/devices/system/cpu/cpuX/online.

However, aio_complete() called from I/O interrupt can potentially call put_ioctx with last ref count on ioctx and triggers bug. It is simply incorrect to perform ioctx freeing from aio_complete. The bug is trigger-able from a race between io_destroy() and aio_complete(). A possible scenario: cpu0 cpu1 io_destroy aio_complete wait_for_all_aios { __aio_put_req ... ctx->reqs_active--; if (!ctx->reqs_active) return; } ... put_ioctx(ioctx) put_ioctx(ctx); __put_ioctx bam! Bug trigger! The real problem is that the condition check of ctx->reqs_active in wait_for_all_aios() is incorrect that access to reqs_active is not being properly protected by spin lock. This patch adds that protective spin lock, and at the same time removes all duplicate ref counting for each kiocb as reqs_active is already used as a ref count for each active ioctx. This also ensures that buggy call to flush_workqueue() in softirq context is eliminated.

sd_probe() calls class_device_add() even before initializing the sdkp->device variable. class_device_add() eventually results in the user mode udev program to be called. udev program can read the the allow_restart attribute of the newly created scsi device. This is resulting in a crash as the show function for allow_restart (i.e sd_show_allow_restart) returns the attribute value by reading the sdkp->device->allow_restart variable. As the sdkp->device is not initialized before calling the user mode hotplug helper, this results in a crash. The patch below solves it by calling class_device_add() only after the necessary fields in the scsi_disk structure are initialized properly.

For all JMicrons except for 361 and 368, AHCI mode enable bits in the Control(1) should be set. This used to be done in both ahci and pata_jmicron but while moving programming to PCI quirk, it was removed from ahci part while still left in pata_jmicron. The implemented JMicron PCI quirk was incorrect in that it didn't program AHCI mode enable bits. If pata_jmicron is loaded first and programs those bits, the ahci ports work; otherwise, ahci device detection fails miserably. This patch makes JMicron PCI quirk clear SATA IDE mode bits and set AHCI mode bits and remove the respective part from pata_jmicron. Tested on JMB361, 363 and 368.

This reverts commit e4f0ae0e. It's not wrong, but it's not right either, and everybody seems to agree that the right fix is probably to do the ccr3 write after the ccr4 one (and that we also should clean it up a bit). And after that we need to really validate that all the bits that we write to ccr4 actually do work. The old 2.6.19 code was insane, and basically didn't change ccr4 at all (even though it certainly looks like it was the *intent* to do so). So let's revert the change that may fix things, just because it's not what was actually ever tested when the code was written, even if it _was_ the intent. There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was started by the patch that now gets reverted, and that discussion may well contain the proper long-term fix.
