* mx51: fix usb clock supportArnaud Patard (Rtp)2011-01-03
| | | | | | | | | Current code doesn't really enable the usb clocks so if they're disabled when booting linux, the kernel/machine will hang as soon as someone is trying to read a usb register Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | This patch is fixing some issues : - MXC_OTG_UCTRL_OPM_BIT is for USBCTRL register and not PHYCTRL register. - the MXC_EHCI_WAKEUP_ENABLED check was only clearing the bits so never allows to set them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit a1afb637(switch /proc/irq/*/spurious to seq_file) all /proc/irq/XX/spurious files show the information of irq 0. Current irq_spurious_proc_open() passes on NULL as the 3rd argument, which is used as an IRQ number in irq_spurious_proc_show(), to the single_open(). Because of this, all the /proc/irq/XX/spurious file shows IRQ 0 information regardless of the IRQ number. To fix the problem, irq_spurious_proc_open() must pass on the appropreate data (IRQ number) to single_open().

The code that looks for duplicates uses strncmp in a binary GUID, which may contain zero bytes. The right function is memcmp, which is also used in another section of wmi code. It was finding 49142400-C6A3-40FA-BADB-8A2652834100 as a duplicate of 39142400-C6A3-40FA-BADB-8A2652834100. Since the first byte is the fourth printed, they were found as equal by strncmp.

The DSDT also reference a WIMAX device, which is not present on this model. This patch adds two new files: wwan and wimax to control WWAN and WIMAX devices. It does not use rfkill, because like WLED and BLED, we don't know yet that the two ACPI functions will always control the radio, they may control only the leds on some hardware.

When a cpu gets offlined it schedules the idle process which, before killing its own cpu, will call tick_nohz_stop_sched_tick(). That function in turn will call arch_needs_cpu() in order to check if the local tick can be disabled. On offline cpus this function should naturally return 0 since regardless if the tick gets disabled or not the cpu will be dead short after. That is besides the fact that __cpu_disable() should already have made sure that no interrupts on the offlined cpu will be delivered anyway. In this case it prevents tick_nohz_stop_sched_tick() to call select_nohz_load_balancer(). No idea if that really is a problem. However what made me debug this is that on 2.6.32 the function get_nohz_load_balancer() is used within __mod_timer() to select a cpu on which a timer gets enqueued. If arch_needs_cpu() returns 1 then the nohz_load_balancer cpu doesn't get updated when a cpu gets offlined. It may contain the cpu number of an offline cpu. In turn timers get enqueued on an offline cpu and not very surprisingly they never expire and cause system hangs. This has been observed 2.6.32 kernels. On current kernels __mod_timer() uses get_nohz_timer_target() which doesn't have that problem. However there might be other problems because of the too early exit tick_nohz_stop_sched_tick() in case a cpu goes offline. This specific bug was indrocuded with 3c5d92a0 "nohz: Introduce arch_needs_cpu". In this case a cpu hotplug notifier is used to fix the issue in order to keep the normal/fast path small. All we need to do is to clear the condition that makes arch_needs_cpu() return 1 since it is just a performance improvement which is supposed to keep the local tick running for a short period if a cpu goes idle. Nothing special needs to be done except for clearing the condition.

This mutex needs to be removed because of the need for the expire ioctl to call back to the daemon to perform a umount and receive a completion status (via another ioctl). This should be fine as the new ioctl interface uses much of the same code and it has been used without a mutex for around a year without issue, as was the original intention.

It didn't hurt the performance of multiple lookup for none-existed files anyway, while regresses a bit in the first try after a file deletion.
