The patch below is necessary for 115200 baud on an OMAP1510 internal UART. It's been in the linux-omap tree for some time and with it applied to a vanilla Linus git tree the serial console on the Amstrad Delta (which is OMAP1510 based and whose initial bootloader runs at 115200) works fine (it doesn't without it).

I think register ranges obviously need to be claimed/released for all UARTs including those with UPIO_MEM32 and UPIO_TSI iotype. Also, serial8250_request_rsa_resources() returns false positives with UPIO_MEM32, UPIO_AU, and UPIO_TSI iotype -- I don't think this makes any sense.

According to the existing code, Nokia only make single-port cards, but are detected as multi-port cards. Handle this in roughly the same way via the config quirk - forcing it to be a real single port card (info->multi=0) changes the way we allocate the IO memory, which might stop the card working.

Move IBM quirk handling into its own quirk entry. Note that doing quirk handling after we've registered the ports is racy, but since I don't know if moving this will have an undesired effect, it's probably better to leave where it is. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

- rename multi_id table to serial_quirk / quirks[] - use named initialisers - store a pointer to the quirk table in the serial_info structure so we can use the quirk table entry later. - apply multi-port quirk after the multi-port guessing code, but only if it's != -1.

m32r_sio re-uses a custom defined BASE_BAUD from asm/serial.h, and replaces SERIAL_PORT_DFNS with its own driver private copy. Since asm/serial.h is supposed to define 8250-based ports using these symbols, this isn't a sane idea. Hence, eliminate asm/serial.h from m32r_sio.c.

We only need the timestamp on COOKIE-ECHO chunks, so instead of always timestamping every SCTP packet, let common code timestamp if the socket option is set. For COOKIE-ECHO, simply get the time of day if we don't have a timestamp. This introduces a small possibility that the cookie may be considered expired, but it will be renegotiated.

Currently if the sender is sending small messages, it can cause a receiver to run out of receive buffer space even when the advertised receive window is still open and results in packet drops and retransmissions. Including a overhead while updating the sender's view of peer receive window will reduce the chances of receive buffer space overshooting the receive window.

MSI is defined to be 32-bit write. The 5706 does 64-bit MSI writes with byte enables disabled on the unused 32-bit word. This is legal but causes problems on the AMD 8132 which will eventually stop responding after a while. Without this patch, the MSI test done by the driver during open will pass, but MSI will eventually stop working after a few MSIs are written by the device. AMD believes this incompatibility is unique to the 5706, and prefers to locally disable MSI rather than globally disabling it using pci_msi_quirk. Update version to 1.4.45.

Fix obscure race condition in kernel/cpuset.c attach_task() code. There is basically zero chance of anyone accidentally being harmed by this race. It requires a special 'micro-stress' load and a special timing loop hacks in the kernel to hit in less than an hour, and even then you'd have to hit it hundreds or thousands of times, followed by some unusual and senseless cpuset configuration requests, including removing the top cpuset, to cause any visibly harm affects. One could, with perhaps a few days or weeks of such effort, get the reference count on the top cpuset below zero, and manage to crash the kernel by asking to remove the top cpuset. I found it by code inspection. The race was introduced when 'the_top_cpuset_hack' was introduced, and one piece of code was not updated. An old check for a possibly null task cpuset pointer needed to be changed to a check for a task marked PF_EXITING. The pointer can't be null anymore, thanks to the_top_cpuset_hack (documented in kernel/cpuset.c). But the task could have gone into PF_EXITING state after it was found in the task_list scan. If a task is PF_EXITING in this code, it is possible that its task->cpuset pointer is pointing to the top cpuset due to the_top_cpuset_hack, rather than because the top_cpuset was that tasks last valid cpuset. In that case, the wrong cpuset reference counter would be decremented. The fix is trivial. Instead of failing the system call if the tasks cpuset pointer is null here, fail it if the task is in PF_EXITING state. The code for 'the_top_cpuset_hack' that changes an exiting tasks cpuset to the top_cpuset is done without locking, so could happen at anytime. But it is done during the exit handling, after the PF_EXITING flag is set. So if we verify that a task is still not PF_EXITING after we copy out its cpuset pointer (into 'oldcs', below), we know that 'oldcs' is not one of these hack references to the top_cpuset.

With CONFIG_DEBUG_LOCK_ALLOC turned off i was getting sporadic failures in the locking self-test: ------------> | Locking API testsuite: ---------------------------------------------------------------------------- | spin |wlock |rlock |mutex | wsem | rsem | -------------------------------------------------------------------------- A-A deadlock: ok | ok | ok | ok | ok | ok | A-B-B-A deadlock: ok | ok | ok | ok | ok | ok | A-B-B-C-C-A deadlock: ok | ok | ok | ok | ok | ok | A-B-C-A-B-C deadlock: ok | ok | ok | ok | ok | ok | A-B-B-C-C-D-D-A deadlock: ok |FAILED| ok | ok | ok | ok | A-B-C-D-B-D-D-A deadlock: ok | ok | ok | ok | ok | ok | A-B-C-D-B-C-D-A deadlock: ok | ok | ok | ok | ok |FAILED| after much debugging it turned out to be caused by accidental chain-hash key collisions. The current hash is: #define iterate_chain_key(key1, key2) \ (((key1) << MAX_LOCKDEP_KEYS_BITS/2) ^ \ ((key1) >> (64-MAX_LOCKDEP_KEYS_BITS/2)) ^ \ (key2)) where MAX_LOCKDEP_KEYS_BITS is 11. This hash is pretty good as it will shift by 5 bits in every iteration, where every new ID 'mixed' into the hash would have up to 11 bits. But because there was a 6 bits overlap between subsequent IDs and their high bits tended to be similar, there was a chance for accidental chain-hash collision for a low number of locks held. the solution is to shift by 11 bits: #define iterate_chain_key(key1, key2) \ (((key1) << MAX_LOCKDEP_KEYS_BITS) ^ \ ((key1) >> (64-MAX_LOCKDEP_KEYS_BITS)) ^ \ (key2)) This keeps the hash perfect up to 5 locks held, but even above that the hash is still good because 11 bits is a relative prime to the total 64 bits, so a complete match will only occur after 64 held locks (which doesnt happen in Linux). Even after 5 locks held, entropy of the 5 IDs mixed into the hash is already good enough so that overlap doesnt generate a colliding hash ID. with this change the false positives went away.
