2009-11-02MIPS: BCM63xx: Prepare for watchdog supportFlorian Fainelli2-1/+38
This patch prepares the board code to register a bcm63xx_wdt platform_device that we are going to use in a subsequent patch. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-11-02MIPS: BCM63xx: Make bcm63xx_uart_register an initfuncFlorian Fainelli3-10/+1
This patch removes the calls to bcm63xx_uart_register in board_bcm963xx.c and make bcm63xx_uart_register an initfunc.

This patch fixes a lockup on BCM6345 where setting the PLL soft reset bit will also lock the other blocks including UART. Instead of setting only the PLL soft reset bit in the software reset register, set this bit but do not touch the others.

2009-11-02MIPS: Don't write ones to reserved entryhi bits.Ralf Baechle1-5/+5
We've silently been relying on the hardware chopping off excess, reserved ASID bits for no better reason that it saving an instruction. Because we already have: #define cpu_asid(cpu, mm) (cpu_context((cpu), (mm)) & ASID_MASK) in <asm/mmu_context.h>. We can use a cleanup to avoid writing non-zero bits into the reserved entryhi bits.

2009-10-29[S390] smp: fix sigp sense handlingHeiko Carstens2-1/+1
sigp sense only returns the status of a cpu if it is non zero. If the status of the sensed cpu is all zeros condition code 0 (accpeted) is set and no status bits are returned. The current code however assumes that a status was returned and tests bits in it. This means uninitalized data is accessed with random results. Worst case is that the code that checks if cpu is offline on cpu hotplug assumes that the target cpu is offline while it is still running. This leads potentially to memory corruption since resources that are still needed by the target cpu will be freed and could be resused while still in use.

2009-10-29[S390] smp: fix sigp stop handlingHeiko Carstens3-6/+6
According to the architecture a cpu must not necessarily enter stopped state after completion of a sigp instruction with "stop" order code. So remove the BUG() statement after self sending sigp stop to avoid that it ever gets reached. Also add a sigp busy check to make sure that the order gets delivered.

2009-10-29[S390] smp: fix prefix handling of offlined cpusHeiko Carstens1-0/+2
Offlined cpus still have valid prefix register contents. Dumpers will store the register contents of a cpu to the location where its prefix register points to. For offlined cpus the area (lowcore) has been freed and the dumper would write the uninteresting contents of the offline cpu to a memory location which might be in use by some other component and destroy valueable information. To fix this set the prefix register of offline cpus to absolute address zero again. This prevents the current dumpers to write to random memory locations.

2009-10-27powerpc/ppc64: Use preempt_schedule_irq instead of preempt_scheduleBenjamin Herrenschmidt1-20/+21
Based on an original patch by Valentine Barshak <vbarshak@ru.mvista.com> Use preempt_schedule_irq to prevent infinite irq-entry and eventual stack overflow problems with fast-paced IRQ sources. This kind of problems has been observed on the PASemi Electra IDE controller. We have to make sure we are soft-disabled before calling preempt_schedule_irq and hard disable interrupts after that to avoid unrecoverable exceptions. This patch also moves the "clrrdi r9,r1,THREAD_SHIFT" out of the #ifdef CONFIG_PPC_BOOK3E scope, since r9 is clobbered and has to be restored in both cases.

2009-10-27sh: Fix hugetlbfs dependencies for SH-3 && MMU configurations.Paul Mundt2-1/+6
The hugetlb dependencies presently depend on SUPERH && MMU while the hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This unfortunately allows SH-3 + MMU configurations to enable hugetlbfs without a corresponding HPAGE_SHIFT definition, resulting in the build blowing up. As SH-3 doesn't support variable page sizes, we tighten up the dependenies a bit to prevent hugetlbfs from being enabled. These days we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using that rather than adding to the list of corner cases in fs/Kconfig.

2009-10-26sh: Check for return_to_handler when unwinding the stackMatt Fleming1-0/+22
When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.

2009-10-26sh: __irq_entry annotate do_IRQ().Paul Mundt1-1/+2
This adds an __irq_entry annotation for do_IRQ() so that the IRQ annotation in the function graph tracer works as advertized. We already have the IRQENTRY section wired up, so this is just a trivial addition to actually make use of it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-10-22omap4: Allow omap_serial_early_init() for OMAP4430 boardSantosh Shilimkar2-2/+4
This patch enables omap_serial_early_init() function for OMAP4430 SDP. Without this the bootup would throw oops in omap_serial_init(). Note that the ifndef CONFIG_ARCH_OMAP4 is split into two sections to enable omap_serial_early_init(). This ifndef cannot be removed until omap4 clock framework is implemented.

2009-10-22omap3: PM: enable UART3 module wakeupsKevin Hilman1-3/+4
UART3 is in the PER powerdomain. If PER goes idle/inactive independently of CORE, for UART3 to wakeup it must have its wakeup enable bits setup in PM_WKEN_PER. This patch enables these bits. The reason it works when PER and CORE work together is because when CORE goes inactive/retention, the IOPAD wakeups are enabled and trigger UART3 wakeup. Without this patch, when the UART inactivity timer fires for UART3, its clocks are disabled and it's unable to wakeup so will be unusable until PER is awoken by another source. Another way of testing is by keeping CORE on during suspend but allowing PER to hit retention # echo 3 > /debug/pm_debug/core_pwrdm/suspend then enter suspend # echo mem > /sys/power/state Without this patch, UART3 will be unable to wakeup the system.
