2012-03-05mac80211: use compare_ether_addr on MAC addresses instead of memcmpFelix Fietkau

2012-03-05RDMA/ucma: Fix AB-BA deadlockHefty, Sean
When we destroy a cm_id, we must purge associated events from the event queue. If the cm_id is for a listen request, we also purge corresponding pending connect requests. This requires destroying the cm_id's associated with the connect requests by calling rdma_destroy_id(). rdma_destroy_id() blocks until all outstanding callbacks have completed. The issue is that we hold file->mut while purging events from the event queue. We also acquire file->mut in our event handler. Calling rdma_destroy_id() while holding file->mut can lead to a deadlock, since the event handler callback cannot acquire file->mut, which prevents rdma_destroy_id() from completing. Fix this by moving events to purge from the event queue to a temporary list. We can then release file->mut and call rdma_destroy_id() outside of holding any locks.

In mwifiex_drv_change_adhoc_chan() we pass channel to mwifiex_bss_ioctl_ibss_channel() which sets the high 16 bits. This works on little endian systems but not on big endian ones. I've changed mwifiex_drv_change_adhoc_chan() to use a 16 bit variable. This matches the other functions in the file. I considered changing mwifiex_change_adhoc_chan() as well but it turns out that the function isn't implemented so I just removed the definition.

2012-03-05b43: prevent firmware on bcm5354 from taking over wrong GPIO pinsHauke Mehrtens
When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent firmware >= 478.104 it runs out of memory after a very short time in OpenWrt after doing an active scan or any thing else where packages are send. This was cased by a gpio misconfiguration, the firmware triggered the GPIO pins used for buttons on some devices and that caused an other driver (OpenWrt diag) listening for these buttons irqs to send many messages to the user space. This patch fixes the bug for my devices (Asus WL-520GU) and makes it work with firmware 666.2. Now the firmware just uses LED GPIO pin number 1 and not the button pins any more.

2012-03-05ath6kl: Restrict memcpy to bounce buffer only for write requestRaja Mani
No need to copy received local buffer content to bounce buffer (DMA buffer) while performing sync READ operation from the chip. It's applicable for only WRITE operation. Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2012-03-05IB/iser: Post initial receive buffers before sending the final login requestOr Gerlitz
An iser target may send iscsi NO-OP PDUs as soon as it marks the iSER iSCSI session as fully operative. This means that there is window where there are no posted receive buffers on the initiator side, so it's possible for the iSER RC connection to break because of RNR NAK / retry errors. To fix this, rely on the flags bits in the login request to have FFP (0x3) in the lower nibble as a marker for the final login request, and post an initial chunk of receive buffers before sending that login request instead of after getting the login response.

For some weird (freudian?) reason, commit 435792d "ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp" unintentionally changed the mailbox's initcall instead of the iommu's. Fix that.

2012-03-05drm/gma500: Fix Cedarview boot failures in 3.3-rcAlan Cox
Production GMA3600/3650 hardware turns out to be subtly different to the development platforms. This combined with a minor driver bug is causing the kernel to hang on these platforms. This patch does the following - turn down a couple of messages that were meant to be debug and are causing much confusion - ensure the hotplug interrupt is disabled on Cedartrail systems. - fix a bug where gtt roll mode called psbfb_sync, which tries to sync the 2D engine. On other devices it is harmless as the 2D engine is present but not in use when in gtt roll mode, on Cedartrail it causes a hang Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
