* [ARM] 3603/1: AT91RM9200 remove old filesAndrew Victor2006-06-20
| | | | | | | | | | | | Patch from Andrew Victor This patch removes the now unnecessary include/asm-arm/arch-at91rm9200/pio.h file. The pin configuration is now handled in the platform-device setup code (arch/arm/mach-at91rm9200/devices.c).

* [ARM] 3592/1: AT91RM9200 Serial driver updateAndrew Victor2006-06-19
| | | | | | | | | | | | | | | | | | | | | Patch from Andrew Victor This patch includes a number of updates to the AT91RM9200 serial driver. Changes include: 1. Conversion to a platform_driver. [Ivan Kokshaysky] 2. Replaced all references to AT91RM9200 with AT91. This driver can now also be used for the AT91SAM9216. 3. Allow TIOCM_LOOP to configure local loopback mode. 4. Cleaned up the 'read_status_mask' usage and interrupt handler code. [Chip Coldwell] 5. Suspend/resume support. [David Brownell] There are a few 'unused variable' warning when compiling this - I removed the new DMA support to keep this first patch simpler.

| | | | | | | | | | | | | | Patch from Andrew Victor This patch includes the structures and exported functions required for the platform-device support (added in patch 3585/1). Also adds the arch_identify() function for run-time detection of which AT91 processor the code is running on.

| | | | | | | | | | | | | | | | Patch from Andrew Victor This patch updates the support for the Atmel DK and EK boards. The changes include: 1. Use the new at91_uart_config structure and device registration functions for the UARTs. 2. Registration of I2C and SPI platform devices. 3. The USB Device pullup line is connected to reset, so multidrive needs to be enabled on the line. [Patch from David Brownell].

| | | | | | | | | | | | | | | | | | | | | | | | Patch from Andrew Victor This patch updates the platform device support for the AT91RM9200. The changes include: 1. USB Host device renamed to "at91_ohci" since the driver is also usable on the AT91SAM9261 processor. 2. Enabling multidrive on the USB Device's pullup pin should not be done for all boards. Moved into board-specific files. [Patch from David Brownell] 3. Move enabling of PCMCIA/Compact Flash pins out of the driver. 4. Added SPI device and resources. 5. Added Watchdog device and resources. [Patch from David Brownell] 6. Added UART device and resources. 7.

| | | | | | | | | | | | | | | Patch from Andrew Victor Use a global variable 'last_crtr' to store the time of the last timer tick instead of the ST_RTAR register. It's faster, frees up the ST_RTAR register for other uses, and hopefully makes the code more understandable. [Patch from Peter Menzebach] Also add the SA_TIMER flag to Timer IRQ.

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.)

* [ARM] 3335/1: Old-abi Thumb sys_syscall brokenPaul Brook2006-06-18
| | | | | | | | | | | | | | | | 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.

* [PATCH] arm_timer: remove a racy and obsolete PF_EXITING checkOleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | 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: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] run_posix_cpu_timers: remove a bogus BUG_ON()Oleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | 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).

* [PATCH] sky2: netconsole suspend/resume interactionStephen Hemminger2006-06-17
| | | | | | | | | | | | | 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.

* [PATCH] fix cdrom openJens Axboe2006-06-17
| | | | | | | | | | | | | | | | 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()".
