2019-06-18irqchip/mbigen: Stop printing kernel addressesKefeng Wang1-2/+1
After commit ad67b74d2469d9b8 ("printk: hash addresses printed with %p"), it will print "____ptrval____" instead of actual addresses when mbigen create domain fails, Hisilicon MBIGEN-V2 HISI0152:00: Failed to create mbi-gen@(____ptrval____) irqdomain Hisilicon MBIGEN-V2: probe of HISI0152:00 failed with error -12 dev_xxx() helper contains the device info, HISI0152:00, which stands for mbigen ACPI HID and its UID, we can identify the failing probed mbigen, so just remove the printing "mgn_chip->base", and also add missing "\n".

2019-06-11irqchip/qcom: Use struct_size() in devm_kzalloc()Gustavo A. R. Silva1-3/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = devm_kzalloc(dev, size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); Notice that, in this case, variable alloc_sz is not necessary, hence it is removed. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

csky_mpintc_handler() ->handle_domain_irq() ->irq_exit() ->invoke_softirq() ->__do_softirq() ->local_irq_enable() If new interrupt coming, it'll get into interrupt trap before return to csky_mpintc_handler().

Add support for Amazon Graviton custom variant of GICv2m, where the message is encoded using the MSI message address, as opposed to standard GICv2m, where the SPI number is encoded in the MSI message data. In addition, the Graviton flavor of GICv2m is used along GICv3 (and not GICv2).
