* irqchip: mips-gic: Support local interruptsAndrew Bresticker2014-11-241-68/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPS GIC supports 7 local interrupts, 2 of which are the GIC local watchdog and count/compare timer. The remainder are CPU interrupts which may optionally be re-routed through the GIC. GIC hardware IRQs 0-6 are now used for local interrupts while hardware IRQs 7+ are used for external (shared) interrupts. Note that the 5 CPU interrupts may not be re-routable through the GIC. In that case mapping will fail and the vectors reported in C0_IntCtl should be used instead. gic_get_c0_compare_int() and gic_get_c0_perfcount_int() will return the correct IRQ number to use for the C0 timer and perfcounter interrupts based on the routability of those interrupts through the GIC. A separate irq_chip, with callbacks that mask/unmask the local interrupt on all CPUs, is used for the C0 timer and performance counter interrupts since all other platforms do not use the percpu IRQ API for those interrupts. Malta, SEAD-3, and the GIC clockevent driver have been updated to use local interrupts and the R4K clockevent driver has been updated to poll for C0 timer interrupts through the GIC when the GIC is present.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the GIC properly uses IRQ domains, kill off the per-platform routing tables that were used to make the GIC appear transparent. This includes: - removing the mapping tables and the support for applying them, - moving GIC IPI support to the GIC driver, - properly routing the i8259 through the GIC on Malta, and - updating IRQ assignments on SEAD-3 when the GIC is present. Platforms no longer will pass an interrupt mapping table to gic_init. Instead, they will pass the CPU interrupt vector (2 - 7) that they expect the GIC to route interrupts to. Note that in EIC mode this value is ignored and all GIC interrupts are routed to EIC vector 1.

| | | | | | | | | | | | | | | | | | | | | | | There's no need for platforms to have their own GIC irq_ack/irq_eoi callbacks. irq_ack need only clear the GIC's edge detector on edge-triggered interrupts and there's no need at all for irq_eoi. Also get rid of the mask_ack callback since it's not necessary either.

The interrupt handler, however, was making the assumption that the clockevent device was registered. That could cause a null pointer dereference if the timer interrupt was firing during this narrow window. Fix that by moving the clockevent registration before the interrupt is enabled.

It will fail, with iw events looking like this (in these logs, several sta are trying to come up, but symptom is the same with just one) The patch causing the regression made quite a few changes, but the part I think caused this particular problem was not recalculating the bssid mask when adding and removing interfaces.

The last patch of this pull request ("can: m_can: update to support CAN FD features") adds, as the description says, a new feature to the m_can driver. As the m_can driver has been added in v3.18 there is no risk of causing a regression. Give me a note if this is not okay and I'll create a new pull request without it. There is a patch for the CAN infrastructure by Thomas Körper which fixes calling kfree_skb() from interrupt context. Roman Fietze fixes a typo also in the infrastructure. A patch by Dong Aisheng adds a generic helper function to tell if a skb is normal CAN or CAN-FD frame. Alexey Khoroshilov of the Linux Driver Verification project fixes a memory leak in the esd_usb2 driver. Two patches by Sudip Mukherjee remove unused variables and fixe the signess of a variable. Three patches by me add the missing .ndo_change_mtu callback to the xilinx_can, rcar_can and gs_usb driver. The remaining patches improve the m_can driver: David Cohen adds the missing CONFIG_HAS_IOMEM dependency. Dong Aisheng provides 6 bugfix patches (most important: missing RAM init, sleep in NAPI poll, dlc in RTR). While the last of his patches adds CAN FD support to the driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

But RAM cells suffer a hardware reset and can therefore hold arbitrary content at startup - including parity and/or ECC bits. To prevent the M_CAN controller detecting checksum errors when reading potentially uninitialized TX message RAM content to transmit CAN frames the TX message RAM has to be written with (any kind of) initial data.
