This patch is for Alan Cox as it related to the tty layer. Hopefully the hso driver is again relatively stable with this fix. Signed-off-by:

The HSO changes for kref introduced a recursive spinlock take. All functions which call put_rxbuf_data already have serial->serial_lock grabbed. [Comment to code added-AC] Signed-off-by:

This was not implemented correctly for the pnx8xxx_uart driver. [From further discussion: Correct, you can look to it as two separate bugs: a) the next character is not ignored while it should; b) the status bits 31-8 are copied to the 'ch' variable while they shouldn't. Both bugs prevent correct break signal handling (and therefore correct behaviour of the magic SysRq key). Bug b didn't cause too much trouble earlier because in most situations the status bits are all zero; for this case they unfortunately aren't. ] Signed-off-by:

Most of netmos 9835 hardware is handled by parport-serial. IBM introduces a device which doesn't have any parallel ports and have screwed subdevice PCI id (not corresponding to port numbers). Handle this device (9710:9835 1014:0299) properly. Signed-off-by:

If you issue an ioctl to flush a tty as the line discipline is changing or otherwise unplugged you can get a crash. The bug is very old but the rest of the BKL lock dropping and some very "good" luck on Ingo's part caught an example. Use the correct ldisc_ref form so that we wait for the ldisc change to complete and then flush Signed-off-by:

The host_busy field in struct ide_host defaults to a signed-long, where most arch's test_and_set_bit_* macros use an unsigned long. Change to using an unsigned long, which on ARM removes the following sparse errors: drivers/ide/ide-io.c:681:8: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:681:8: expected unsigned long volatile *p drivers/ide/ide-io.c:681:8: got long volatile *<noident> drivers/ide/ide-io.c:681:8: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:681:8: expected unsigned long volatile *p drivers/ide/ide-io.c:681:8: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> drivers/ide/ide-io.c:695:3: warning: incorrect type in argument 2 (different signedness) drivers/ide/ide-io.c:695:3: expected unsigned long volatile *p drivers/ide/ide-io.c:695:3: got long volatile *<noident> Signed-off-by:

This assertion is incorrect for lockless pagecache. By definition if we have an unpinned page that we are trying to take a speculative reference to, it may become the tail of a compound page at any time (if it is freed, then reallocated as a compound page). It was still a valid assertion for the vmscan.c LRU isolation case, but it doesn't seem incredibly helpful... if somebody wants it, they can put it back directly where it applies in the vmscan code.
