The acer_wmi driver does a DMI scan for quirks, and then sets flags into the "interface" datastructure for some cases. However, the quirks happen real early before "interface" is per se initialized from NULL. The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the end, when "interface" has it's final value.

This fixes a problem spotted with zebra, but not sure if it is necessary a kernel problem. With IPV6 when an address is added to an interface, Zebra creates a duplicate RIB entry, one as a connected route, and other as a kernel route. When an address is added to an interface the RTN_NEWADDR message causes Zebra to create a connected route. In IPV4 when an address is added to an interface a RTN_NEWROUTE message is set to user space with the protocol RTPROT_KERNEL. Zebra ignores these messages, because it already has the connected route. The problem is that route created in IPV6 has route protocol == RTPROT_BOOT. Was this a design decision or a bug? This fixes it. Same patch applies to both net-2.6 and stable.

Authenc works in two stages for encryption, it first encrypts and then computes an ICV. The context memory of the request is used by both operations. The problem is that when an asynchronous encryption completes, we will compute the ICV and then reread the context memory of the encryption to get the original request. It just happens that we have a buffer of 16 bytes in front of the request pointer, so ICVs of 16 bytes (such as SHA1) do not trigger the bug. However, any attempt to uses a larger ICV instantly kills the machine when the first asynchronous encryption is completed. This patch fixes this by saving the request pointer before we start the ICV computation. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Dave Müller sent a diff for the pata_oldpiix that highlighted a problem where a lot of the ATA drivers assume dma_mode == 0 means "no DMA" while the core code uses 0xFF. This turns out to have other consequences such as code doing >= XFER_UDMA_0 also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect set_dma_mode, although some drivers call back into their own set mode code from other points. Having been through the drivers I've added helpers for using_udma/using_mwdma dma_enabled so that people don't open code ranges that may change (eg if UDMA8 appears somewhere) Thanks to David for the initial bits [and added fix for pata_oldpiix from and signed-off-by Dave Mueller <dave.mueller@gmx.ch> -jg] Signed-off-by: NAlan Cox <alan@redhat.com> Signed-off-by: NJeff Garzik <jgarzik@redhat.com>

SIS controllers were blacklisted for PMP as enabling it made device detection fail whether the device was PMP or not - the natural conclusion was the controller chokes on SRST w/ pmp==15. However, it turned out that the controller just didn't like issuing SRST after hardreset w/o clearing SError first. Interestingly, the SRST itself succeeds but the following commands fail. If SError is cleared between hardreset and SRST, which is the default behavior now, everything works fine and SIS controllers work with PMPs happily. Remove PMP blacklisting for SIS AHCIs.

Save SControl during probing and restore it on detach. This prevents adjustments made by libata drivers to seep into the next driver which gets attached (be it a libata one or not). It's not clear whether SControl also needs to be restored on suspend. The next system to have control (ACPI or kexec'd kernel) would probably like to see the original SControl value but there's no guarantee that a link is gonna keep working after SControl is adjusted without a reset and adding a reset and modified recovery cycle soley for this is an overkill. For now, do it only for detach. Signed-off-by: NTejun Heo <tj@kernel.org> Signed-off-by: NJeff Garzik <jgarzik@redhat.com>

As an optimization, follow-up SRST used to be skipped if classification wasn't requested even when hardreset requested it via -EAGAIN. However, some hardresets can't wait for device readiness and skipping SRST can cause timeout or other failures during revalidation. Always perform follow-up SRST if hardreset returns -EAGAIN. This makes reset paths more predictable and thus less error-prone. While at it, move hardreset error checking such that it's done right after hardreset is finished. This simplifies followup SRST condition check a bit and makes the reset path easier to modify. Signed-off-by: NTejun Heo <tj@kernel.org> Signed-off-by: NJeff Garzik <jgarzik@redhat.com>
