2010-05-17[S390] idle time accounting vs. machine checksMartin Schwidefsky1-1/+2
A machine check can interrupt the i/o and external interrupt handler anytime. If the machine check occurs while the interrupt handler is waking up from idle vtime_start_cpu can get executed a second time and the int_clock / async_enter_timer values in the lowcore get clobbered. This can confuse the cpu time accounting. To fix this problem two changes are needed. First the machine check handler has to use its own copies of int_clock and async_enter_timer, named mcck_clock and mcck_enter_timer. Second the nested execution of vtime_start_cpu has to be prevented. This is done in s390_idle_check by checking the wait bit in the program status word.

2010-05-15Fix the regression created by "set S_DEAD on unlink()..." commitAl Viro1-0/+1
1) i_flags simply doesn't work for mount/unlink race prevention; we may have many links to file and rm on one of those obviously shouldn't prevent bind on top of another later on. To fix it right way we need to mark _dentry_ as unsuitable for mounting upon; new flag (DCACHE_CANT_MOUNT) is protected by d_flags and i_mutex on the inode in question. Set it (with dont_mount(dentry)) in unlink/rmdir/etc., check (with cant_mount(dentry)) in places in namespace.c that used to check for S_DEAD. Setting S_DEAD is still needed in places where we used to set it (for directories getting killed), since we rely on it for readdir/rmdir race prevention. 2) rename()/mount() protection has another bogosity - we unhash the target before we'd checked that it's not a mountpoint. Fixed. 3) ancient bogosity in pivot_root() - we locked i_mutex on the right directory, but checked S_DEAD on the different (and wrong) one. Noticed and fixed.

2010-05-13serial: imx.c: fix CTS trigger level lower to avoid lost charsValentin Longchamp1-1/+9
The imx CTS trigger level is left at its reset value that is 32 chars. Since the RX FIFO has 32 entries, when CTS is raised, the FIFO already is full. However, some serial port devices first empty their TX FIFO before stopping when CTS is raised, resulting in lost chars. This patch sets the trigger level lower so that other chars arrive after CTS is raised, there is still room for 16 of them.

2010-05-13tty: Fix unbalanced BKL handling in error pathAlan Cox1-0/+1
Arnd noted: After the "retry_open:" label, we first get the tty_mutex and then the BKL. However a the end of tty_open, we jump back to retry_open with the BKL still held. If we run into this case, the tty_open function will be left with the BKL still held.
