2012-03-13ARM: imx6q: convert to twd_local_timer_register() interfaceMarc Zyngier
Add support for the new smp_twd runtime registration interface to the imx6q platforms, and remove the old compile-time support. The imx6q DTS file is updated to match the TWD DT documentation. Also present in this patch a DTS fix to the timer interrupt routing (the PPI connection uses bits [15:8]) and trigger (rising edge).

2012-03-13ARM: smp_twd: add runtime registration supportMarc Zyngier
Add support for the new registration interface to smp_twd. Platforms can populate a struct twd_local_timer with MMIO and IRQ resources, and then call twd_local_timer_register() to have the timer registered with the core. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2012-03-13ARM: local timers: introduce a new registration interfaceMarc Zyngier
In order to switch to a runtime selectable local timer, add a registration interface that timer drivers can use to register to the core. local_timer_setup() and local_timer_stop() are made weak symbols in order not to break existing setups. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2012-03-13ARM: smp_twd: make local_timer_stop a symbol instead of a #defineMarc Zyngier
When CONFIG_HAVE_ARM_TWD is selected, local_timer_stop is a #define, while all other local timers are using a real function. Convert it to an alias of twd_timer_stop, as it helps converting all local timers to another internal API in a sane way. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2012-03-13iomux-mx25.h slew rate adjusted for LCD __LD pinsMehnert
For some reason (sadly i don't identifying the patch right now) two LCD data lines configured PAD_CTL_SRE_SLOW (wrong slew rate) since Kernel 3.1. MX25_PAD_GPIO_E__LD16 and MX25_PAD_GPIO_F__LD17 This results in an fauly behaviour and strange color effects. To ensure that all LCD data pins configured with the proper slew rate, this patch changes to IOMUX define of all LCD __LDxx pins to PAD_CTL_SRE_FAST. This problem may affect other mx25 platforms like mx25pdk. Sadly i can't test it. Of course this problem shouldn't occur when you done your LCD muxing correctly in the bootloader.

2012-03-13x86: Rename trap_no to trap_nr in thread_structSrikar Dronamraju
There are precedences of trap number being referred to as trap_nr. However thread struct refers trap number as trap_no. Change it to trap_nr. Also use enum instead of left-over literals for trap values. This is pure cleanup, no functional change intended.

2012-03-13x86/ioapic: Add register level checks to detect bogus io-apic entriesSuresh Siddha
With the recent changes to clear_IO_APIC_pin() which tries to clear remoteIRR bit explicitly, some of the users started to see "Unable to reset IRR for apic .." messages. Close look shows that these are related to bogus IO-APIC entries which return's all 1's for their io-apic registers. And the above mentioned error messages are benign. But kernel should have ignored such io-apic's in the first place. Check if register 0, 1, 2 of the listed io-apic are all 1's and ignore such io-apic.
