* sh: replace CONFIG_GENERIC_GPIO by CONFIG_GPIOLIBAlexandre Courbot2013-03-205-5/+5
| | | | | | | | | | | | | SH GPIO drivers all use gpiolib and CONFIG_GENERIC_GPIO is only selected through CONFIG_GPIOLIB, yet some compilation units depended on CONFIG_GENERIC_GPIO. Make them depend on CONFIG_GPIOLIB instead since it is more accurate and prepares us for the future removal of CONFIG_GENERIC_GPIO.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Failed buffer readahead can leave the buffer in the cache marked with an error. Most callers that then issue a subsequent read on the buffer do not zero the b_error field out, and so we may incorectly detect an error during IO completion due to the stale error value left on the buffer. Avoid this problem by zeroing the error before IO submission. This ensures that the only IO errors that are detected those captured from are those captured from bio submission or completion.

* | PCI: Use ROM images from firmware only if no other ROM source availableMatthew Garrett2013-03-191-20/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mantas Mikulėnas reported that his graphics hardware failed to initialise after commit f9a37be0f02a ("x86: Use PCI setup data"). The aim of this commit was to ensure that ROM images were available on some Apple systems that don't expose the GPU ROM via any other source. In this case, UEFI appears to have provided a broken ROM image that we were using even though there was a perfectly valid ROM available via other sources. The simplest way to handle this seems to be to just re-order pci_map_rom() and leave any firmare-supplied ROM to last.

Currently the limit 128 is choosen somewhat arbitrary and just ensures that we can fill up the fragment cache with empty packets up to the default ip_frag_high_thresh limits. It should just protect from list iteration eating considerable amounts of cpu. If we reach the maximum length in one hash bucket a warning is printed. This is implemented on the caller side of inet_frag_find to distinguish between the different users of inet_fragment.c. I dropped the out of memory warning in the ipv4 fragment lookup path, because we already get a warning by the slab allocator.

This is bad because if we clone the parent before it had a chance to clear the flag, the child inherits the tsq_flags value, and next tcp_release_cb() on the child will decrement sk_refcnt. Result is that we might free a live TCP socket, as reported by Dormando. IPv4: Attempt to release TCP socket in state 1 Fix this issue by testing sk_state against TCP_LISTEN early, so that we set TCP_MTU_REDUCED_DEFERRED on appropriate sockets (not a LISTEN one) This bug was introduced in commit 563d34d05786 (tcp: dont drop MTU reduction indications) Reported-by: dormando <dormando@rydia.net> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

Regarding the Bluetooth bits, Gustavo says: "I have these two patches for 3.9, these add support for two more devices to the bluetooth drivers." Along with those, we have a few wireless driver fixes... Bing Zhao provides an mwifiex to prevent an out-of-bounds memory access. John Crispin offers a Kconfig fix to enable some otherwise dead code in rt2x00. The correct symbols were added in -rc1 through a different tree, but the symbols for enabling the wireless driver didn't match. Larry Finger brings an rtlwifi fix for a scheduling while atomic bug, and another fix for a reassociation problem caused by failing to clear the BSSID after a disconnect. ==================== Signed-off-by: David S.
