Export handle_edge_irq() and irq_to_desc() to modules to allow them to do things such as __irq_set_handler_locked(...., handle_edge_irq); This fixes ERROR: "handle_edge_irq" [drivers/gpio/gpio-pch.ko] undefined! ERROR: "irq_to_desc" [drivers/gpio/gpio-pch.ko] undefined! when gpio-pch is being built as a module. This was introduced by commit df9541a6 ("gpio: pch9: Use proper flow type handlers") that added __irq_set_handler_locked(d->irq, handle_edge_irq); but handle_edge_irq() was not exported for modules (and inlined __irq_set_handler_locked() requires irq_to_desc() exported as well) Signed-off-by: NJiri Kosina <jkosina@suse.cz> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

由 Thomas Gleixner 提交于
Jean-Francois Dagenais reported: Configuring a gpio pin with the gpio-pch driver with "IRQF_TRIGGER_LOW | IRQF_ONESHOT" generates an interrupt storm for threaded ISR until the ISR thread actually gets to physically clear the interrupt on the triggering chip!! The immediate observable symptom is the high CPU usage for my ISR thread task and the interrupt count in /proc/interrupts incrementing radically. The driver is wrong in several ways: 1) Using handle_simple_irq() does not provide proper flow control handling. In the case of oneshot threaded handlers for the demultiplexed interrupts this results in an interrupt storm because the simple handler does not deal with masking/unmasking. Even without threaded oneshot handlers an interrupt storm for level type interrupts can easily be triggered when the interrupt is disabled and the interrupt line is activated from the device. 2) Acknowlegding the demultiplexed interrupt before calling the handler is wrong for level type interrupts. 3) The set_type function unconditionally enables the interrupt. It's supposed to set the type and nothing else. The unmasking is done by the core code. Move the acknowledge code into a separate function and add it to the demux irqchip callbacks. Remove the unconditional enabling from the set_type() callback and set the proper flow handlers depending on the selected type (level/edge).

So we have another case of paca->irq_happened getting out of sync with the HW irq state. This can happen when a perfmon interrupt occurs while soft disabled, as it will return to a soft disabled but hard enabled context while leaving a stale PACA_IRQ_HARD_DIS flag set. This patch fixes it, and also adds a test for the condition of those flags being out of sync in arch_local_irq_restore() when CONFIG_TRACE_IRQFLAGS is enabled. This helps catching those gremlins faster (and so far I can't seem see any anymore, so that's good news). Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

Why is there less MemFree than there used to be? It perturbed a test, so I've just been bisecting linux-next, and now find the offender went upstream yesterday. Commit 93278814 "mm: fix division by 0 in percpu_pagelist_fraction()" mistakenly initialized percpu_pagelist_fraction to the sysctl's minimum 8, which leaves 1/8th of memory on percpu lists (on each cpu??); but most of us expect it to be left unset at 0 (and it's not then used as a divisor).
