The driver currently leaves GPIO IRQs unmasked even when the GPIO IRQ client has released the GPIO IRQ. This allows the HW to raise IRQs, and SW to process them, after shutdown. Fix this by masking the IRQ when it's shut down. This is usually taken care of by the irqchip core, but since this driver has a custom irq_shutdown implementation, it must do this explicitly itself.

This motherboard also has a PCI device which advertises no codecs. The PCI ID is 1022:1487 and PCI SSID is 1022:d102. As this is using the AMD vendor ID, don't blacklist for now in case other boards have a working audio device with the same ssid.

Before this patch, function gfs2_quota_lock checked if it was called from a privileged user, and if so, it bypassed the quota check: superuser can operate outside the quotas. That's the wrong place for the check because the lock/unlock functions are separate from the lock_check function, and you can do lock and unlock without actually checking the quotas.
This patch moves the check to gfs2_quota_lock_check.

This reverts commit df5db5f9ee112e76b5202fbc331f990a0fc316d6.
This patch fixes a regression: patch df5db5f9ee112 allowed function run_queue() to bypass its call to do_xmote() if revokes were queued for the glock. That's wrong because its call to do_xmote() is what is responsible for calling the go_sync() glops functions to sync both the ail list and any revokes queued for it. By bypassing the call, gfs2 could get into a stand-off where the glock could not be demoted until its revokes are written back, but the revokes would not be written back because do_xmote() was never called.
It "sort of" works, however, because there are other mechanisms like the log flush daemon (logd) that can sync the ail items and revokes, if it deems it necessary. The problem is: without file system pressure, it might never deem it necessary.

There is a potential race in fscache operation enqueuing for reading and copying multiple pages from cachefiles to netfs. The problem can be seen easily on a heavy loaded system (for example many processes reading files continually on an NFS share covered by fscache triggered this problem within a few minutes).
The race is due to cachefiles_read_waiter() adding the op to the monitor to_do list and then then drop the object->work_lock spinlock before completing fscache_enqueue_operation(). Once the lock is dropped, cachefiles_read_copier() grabs the op, completes processing it, and makes it through fscache_retrieval_complete() which sets the op->state to the final state of FSCACHE_OP_ST_COMPLETE(4). When cachefiles_read_waiter() finally gets through the remainder of fscache_enqueue_operation() it sees the invalid state, and hits the ASSERTCMP and the following oops is seen: [ 2259.612361] FS-Cache: [ 2259.614785] FS-Cache: Assertion failed [ 2259.618639] FS-Cache: 4 == 5 is false [ 2259.622456] ------------[ cut here ]------------ [ 2259.627190] kernel BUG at fs/fscache/operation.c:70! ...

I ran into a randconfig build failure with CONFIG_FIXED_PHY=m and CONFIG_GIANFAR=y:
x86_64-linux-ld: drivers/net/ethernet/freescale/gianfar.o:(.rodata+0x418): undefined reference to `fixed_phy_change_carrier'
It seems the same thing can happen with dpaa and ucc_geth, so change all three to do an explicit 'select FIXED_PHY'.
The fixed-phy driver actually has an alternative stub function that theoretically allows building network drivers when fixed-phy is disabled, but I don't see how that would help here, as the drivers presumably would not work then.
