Initially I had to write to both the MASK and ENABLE registers, otherwise the CPLD would generate tons of spurious interrupts. With the change to the demux handler to disable the muxed line, it is now sufficient to disable the interrupt by writing either the enable or mask register.

The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.

There is a kprobes testcase for the instruction "strd r2, [r3], r4". This has unpredictable behaviour as it uses r3 for register writeback addressing and also stores it to memory. On a cortex A9, this testcase would fail because the instruction writes the updated value of r3 to memory, whereas the kprobes emulation code writes the original value. Fix this by changing testcase to used r5 instead of r3.

Commit 4294f8ba ("ARM: gic: add irq_domain support") defines irq_start as irq_start = (irq_start & ~31) + 16; On a platform with a GIC and a CPU without PPIs, this results in irq_start being off by 16. This patch fixes gic_init so that we only carve out a PPI space when PPIs exist for the GIC being initialised.

When multiple GICs exist on a platform (RealView PB1176/11MP), we must make sure the PM notifier block is only registered once, otherwise we end up corrupting the PM notifier list. The fix is to only register the notifier when initializing the first GIC, as the power management functions seem to iterate over all the registered GICs. Tested on PB11MP and PB1176.

由 Jon Medhurst 提交于
When compiling kprobes-test-thumb.c an error like below may occur: /tmp/ccKcuJcG.s:19179: Error: offset out of range This is caused by the compiler underestimating the size of the inline assembler instructions containing ".space 0x1000" and failing to spill the literal pool in time to prevent the generation of PC relative load instruction with invalid offsets. The fix implemented by this patch is to replace a single large .space directive by a number of 4 byte .space's. This requires splitting the macros which generate test cases for branch instructions into two forms: one with, and one without support for inserting extra code between branch and target.

The bitops functions (e.g. _test_and_set_bit) on ARM do not have unwind annotations and therefore the kernel cannot backtrace out of them on a fatal error (for example, NULL pointer dereference). This patch annotates the bitops assembly macros with UNWIND annotations so that we can produce a meaningful backtrace on error. Callers of the macros are modified to pass their function name as a macro parameter, enforcing that the macros are used as standalone function implementations.

The address spaces, irqs and dma reqs count APIs return the number of corresponding entries in a hwmod including a additional null value or a -1 terminator in the structure introduced recently.

The devices which have multiple hwmods and use device_build_ss are broken with this, as their resources are populated with a extra null value, subsequently the probe fails.
