Patch from Ben Dooks All the S3C24XX based devices currently have similar uart blocks, in the same location. Make the process of adding new uart blocks easier by commonising the device definitions and adding a new init function for the cpu code.

由 David Brownell 提交于
Patch from David Brownell This adds the platform device for SSP/SPI controller, and declares the ads7846 device hooked up to it. Not all Lubbock boards appear to populate the connector needed to use this instead of the ucb1400 chip, but it can always be used as a temperature sensor. In short, this is probably most useful as an example of how to provide the configuration data used by the pxa2xx_spi driver. (Last tested against a slightly earlier version of that driver.)

Patch from Ben Dooks Using the low-level debug routines early in the kernel debug cause the 1:1 mapping to get into the TLB, which is not flushed until after the CPU detection process (which needs the GPIO VA). This patch moves the VA for the GPIO to the same offset as the physical offset of the UART to the GPIO.

Patch from Paul Brook The old-abi sys_syscall syscall is broken when called from Thumb mode. It assumes the syscall number is an Arm syscall number (ie. starts from __NR_OABI_SYSCALL_BASE). In thumb mode syscall numbers start from zero. The patch below fixes this by clearing the nigh bits of the syscall number instead of inverting them. Technically this means we accept some invalid syscall numbers, but I can't see how that could be a problem. The two sets of numbers far apart that unimplemented syscalls should still be rejected.

arm_timer() checks PF_EXITING to prevent BUG_ON(->exit_state) in run_posix_cpu_timers(). However, for some reason it does so only for CPUCLOCK_PERTHREAD case (which is imho wrong). Also, this check is not reliable, PF_EXITING could be set on another cpu without any locks/barriers just after the check, so it can't prevent from attaching the timer to the exiting task. The previous patch makes this check unneeded. Signed-off-by: NOleg Nesterov <oleg@tv-sign.ru> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

do_exit() clears ->it_##clock##_expires, but nothing prevents another cpu to attach the timer to exiting process after that. arm_timer() tries to protect against this race, but the check is racy. After exit_notify() does 'write_unlock_irq(&tasklist_lock)' and before do_exit() calls 'schedule() local timer interrupt can find tsk->exit_state != 0. If that state was EXIT_DEAD (or another cpu does sys_wait4) interrupted task has ->signal == NULL. At this moment exiting task has no pending cpu timers, they were cleanuped in __exit_signal()->posix_cpu_timers_exit{,_group}(), so we can just return from irq.

If the local timer interrupt happens just after do_exit() sets PF_EXITING (and before it clears ->it_xxx_expires) run_posix_cpu_timers() will call check_process_timers() with tasklist_lock + ->siglock held and check_process_timers: t = tsk; do { .... do { t = next_thread(t); } while (unlikely(t->flags & PF_EXITING)); } while (t != tsk); the outer loop will never stop. Actually, the window is bigger. Another process can attach the timer after ->it_xxx_expires was cleared (see the next commit) and the 'if (PF_EXITING)' check in arm_timer() is racy (see the one after that).

A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

I noticed a strange behavior in a tmpfs file system the other day, while building packages - occasionally, and seemingly at random, make decided to rebuild a target. However, only on tmpfs. A file would be created, and if checked, it had a sub-second timestamp. However, after an utimes related call where sub-seconds should be set, they were zeroed instead. In the case that a file was created, and utimes(...,NULL) was used on it in the same second, the timestamp on the file moved backwards. After some digging, I found that this was being caused by tmpfs not having a time granularity set, thus inheriting the default 1 second granularity. Hugh adds: yes, we missed tmpfs when the s_time_gran mods went into 2.6.11. Unfortunately, the granularity of CURRENT_TIME, often used in filesystems, does not match the default granularity set by alloc_super. A few more such discrepancies have been found, but this is the most important to fix now. Signed-off-by: NRobin H.
