| * ocfs2/dlm: Wait on lockres instead of erroring cancel requestsGoldwyn Rodrigues2009-08-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In case a downconvert is queued, and a flock receives a signal, BUG_ON(lockres->l_action != OCFS2_AST_INVALID) is triggered because a lock cancel triggers a dlmunlock while an AST is scheduled. To avoid this, allow a LKM_CANCEL to pass through, and let it wait on __dlm_wait_on_lockres().

| | | | | | | | | | | | | | | | | | | | | | | | | | ocfs2_read_virt_blocks() does BUG when we try to read a block from a file beyond its end. Since this can happen due to filesystem corruption, it is not really an appropriate answer. Make ocfs2_read_quota_block() check the condition and handle it by calling ocfs2_error() and returning EIO.

| * | [ARM] Orion NAND: Make asm volatile avoid GCC pushing ldrd out of the loopSimon Kagstrom2009-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 4.3.3 and 4.4.1 happily moves the dword load instruction out of the loop in orion_nand_read_buf. This patch makes the instruction volatile to avoid the issue. I've discussed this at gcc-help, refer to the thread at http://gcc.gnu.org/ml/gcc-help/2009-08/msg00187.html The early clobber is added to avoid the destination registers and the source register overlapping.

* | | mm: fix hugetlb bug due to user_shm_unlock callHugh Dickins2009-08-243-13/+21

In detail: Assume that can_do_hugetlb_shm() returns true and hence user_shm_lock() is not called in hugetlb_file_setup(). However, user_shm_unlock() is called in any case in shm_destroy() and in the following atomic_dec_and_lock(&up->__count) in free_uid() is executed and if up->__count gets zero, also cleanup_user_struct() is scheduled. Note that sched_destroy_user() is empty if CONFIG_USER_SCHED is not set. However, the ref counter up->__count gets unexpectedly non-positive and the corresponding structs are freed even though there are live references to them, resulting in a kernel oops after a lots of shmget(SHM_HUGETLB)/shmctl(IPC_RMID) cycles and CONFIG_USER_SCHED set. Hugh changed Stefan's suggested patch: can_do_hugetlb_shm() at the time of shm_destroy() may give a different answer from at the time of hugetlb_file_setup(). And fixed newseg()'s no_id error path, which has missed user_shm_unlock() ever since it came in 2.6.9.

In order to get satisfactory response then, we need to employ every noise-reduction trick in the driver's arsenal. After extensive fiddling I've found some good settings: 1) We keep vref on all the time to dramatically reduce settling times (at the cost of a tiny increase in power consumption). 2) Despite 1 the settling time is still non-zero. 500uS is plenty of time for the signals to settle 3) Despite 1 and 2 there's still a little bit of noise around. By setting a pen recheck delay we make the panel feel less touchy and twitchy. Someone with more time and patience myself might be able to tune this numbers further but these settings are now perfectly acceptable for normal use. Tested on ezLCD+101 though should only improve response on other ezLCD+/ favr-32 boards too.

Data in descriptors is accessed simultaneously by the chip (writing status and size when a packet is received) and CPU (reading to check if the packet was received). This isn't a valid usage of PCI DMA API, which requires use of the coherent (consistent) memory for such purpose. Unfortunately e100 chips working in "simplified" RX mode have to store received data directly after the descriptor. Fixing the driver to conform to the API would require using unsupported "flexible" RX mode or receiving data into a coherent memory and using CPU to copy it to network buffers. This patch, while not yet making the driver conform to the PCI DMA API, allows it to work correctly on X86 with swiotlb (while not breaking other architectures).

By accident, setting BSSID of AP before association makes 8187B to successfuly associate even when ENEDCA flag isn't set, which was the case before the mac80211 change. But now the BSSID of AP we are trying to associate is only available after association is successful, and any attempt to associate without the needed flag doesn't work.

The problem can be seen when ibm_newemac instances are slaves of a bonding interface. The bonding interface code uses netif_carrier_ok() to determine the link status of its slaves. When ibm_newemac slave is shutdown with "ifconfig down", the bonding interface won't detect any link status change because netif_carrier_ok() keeps returning TRUE.
