However, this has\nan adverse effect on PCMCIA support on Intel StrongARM and probably PXA\nplatforms.\n\nPCMCIA has several status signals on the socket which can trigger\ninterrupts; some of these status signals depend on the card\u0027s mode\n(whether it is configured in memory or IO mode). For example, cards have\na \u0027Ready/IRQ\u0027 signal: in memory mode, this provides an indication to\nPCMCIA that the card has finished its power up initialization. In IO\nmode, it provides the device interrupt signal. Other status signals\nswitch between on-board battery status and loud speaker output.\n\nIn classical PCMCIA implementations, where you have a specific socket\ncontroller, the controller provides a method to mask interrupts from the\nsocket, and importantly ignore any state transitions on the pins which\ncorrespond with interrupts once masked. This masking prevents unwanted\nevents caused by the removal and application of socket power being\nforwarded.\n\nHowever, on platforms where there is no socket controller, the PCMCIA\nstatus and interrupt signals are routed to standard edge-triggered GPIOs. \nThese GPIOs can be configured to interrupt on rising edge, falling edge,\nor never. This is where the problems start.\n\nEdge triggered interrupts are required to record events while disabled via\nthe usual methods of {free,request,disable,enable}_irq() to prevent\nproblems with dropped interrupts (eg, the 8390 driver uses disable_irq()\nto defer the delivery of interrupts). As a result, these interfaces can\nnot be used to implement the desired behaviour.\n\nThe side effect of this is that if the \u0027Ready/IRQ\u0027 GPIO is disabled via\ndisable_irq() on suspend, and enabled via enable_irq() after resume, we\nwill record the state transitions caused by powering events as valid\ninterrupts, and foward them to the card driver, which may attempt to\naccess a card which is not powered up.\n\nThis leads delays resume while drivers spin in their interrupt handlers,\nand complaints from drivers before they realize what\u0027s happened.\n\nMoreover, in the case of the \u0027Ready/IRQ\u0027 signal, this is requested and\nfreed by the card driver itself; the PCMCIA core has no idea whether the\ninterrupt is requested, and, therefore, whether a call to disable_irq()\nwould be valid. (We tried this around 2.4.17 / 2.5.1 kernel era, and\nended up throwing it out because of this problem.)\n\nTherefore, it was decided back in around 2002 to disable the edge\ntriggering instead, resulting in all state transitions on the GPIO being\nignored. That\u0027s what we actually need the hardware to do.\n\nThe commit above changes this behaviour; it explicitly prevents the \u0027no\ntrigger\u0027 state being selected.\n\nThe reason that request_irq() does not accept the \u0027no trigger\u0027 state is\nfor compatibility with existing drivers which do not provide their desired\ntriggering configuration. The set_irq_type() function is \u0027new\u0027 and not\nused by non-trigger aware drivers.\n\nTherefore, revert this change, and restore previously working platforms\nback to their former state.\n\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nCc: linux@arm.linux.org.uk\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: stable@vger.kernel.org\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "737f24bda723fdf89ecaacb99fa2bf5683c32799", "tree": "35495fff3e9956679cb5468e74e6814c8e44ee66", "parents": [ "8eedce996556d7d06522cd3a0e6069141c8dffe0", "b7c924274c456499264d1cfa3d44063bb11eb5db" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 05 09:20:08 2012 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 05 09:20:08 2012 +0100" }, "message": "Merge branch \u0027perf/urgent\u0027 into perf/core\n\nConflicts:\n\ttools/perf/builtin-record.c\n\ttools/perf/builtin-top.c\n\ttools/perf/perf.h\n\ttools/perf/util/top.h\n\nMerge reason: resolve these cherry-picking conflicts.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "abd2363f6a5f1030b935e0bdc15cf917313b3b10", "tree": "1f4546497af8162a60573203c5b017e2f7fed1f5", "parents": [ "b4e518547da042fdc65bd4bdafd046fed13337d5" ], "author": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Fri Feb 24 08:07:06 2012 -0700" }, "committer": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Fri Feb 24 09:47:23 2012 -0700" }, "message": "irq_domain/mips: Allow irq_domain on MIPS\n\nThis patch makes IRQ_DOMAIN usable on MIPS.

On ARM it works and is required for much of the new\nARM device tree board support.\n\nPowerPC has /not/ been converted to use this new infrastructure. It\nis still missing some features before it can replace the virq\ninfrastructure already in powerpc (see documentation on\nirq_domain_map/unmap for details). Followup patches will add the\nmissing pieces and migrate PowerPC to use irq_domain.\n\nSPARC has its own method of managing interrupts from the device tree\nand is unaffected by this change.\n\nAcked-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\n" }, { "commit": "1dd75f91ae713049eb6baaa640078f3a6549e522", "tree": "24ce9355ca74a6fe6a179e61a9ab9418b17f2eae", "parents": [ "02f8c6aee8df3cdc935e9bdd4f2d020306035dbe" ], "author": { "name": "jhbird.choi@samsung.com", "email": "jhbird.choi@samsung.com", "time": "Thu Jul 21 15:29:14 2011 +0900" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Jul 26 16:24:02 2011 +0200" }, "message": "genirq: Fix wrong bit operation\n\n(!msk \u0026 0x01) should be !(msk \u0026 0x01)\n\nSigned-off-by: Jonghwan Choi \u003cjhbird.choi@samsung.com\u003e\nLink: http://lkml.kernel.org/r/1311229754-6003-1-git-send-email-jhbird.choi@samsung.com\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: stable@kernel.org\n" }, { "commit": "ae891a1b93bf62e9aaa116a7a71312375047fc9f", "tree": "83e821e818654da3e3443ecddd757665251db6e0", "parents": [ "5190f0c030f46b3169205f34f6d9ef480fa39ef2" ], "author": { "name": "Maxin B John", "email": "maxin.john@gmail.com", "time": "Mon Jul 25 17:12:59 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:14 2011 -0700" }, "message": "devres: fix possible use after free\n\ndevres uses the pointer value as key after it\u0027s freed, which is safe but\ntriggers spurious use-after-free warnings on some static analysis tools.\nRearrange code to avoid such warnings.\n\nSigned-off-by: Maxin B.

Replace irq_gc_ack() with some\n{set,clr}_bit variants allows to handle both cases.\n\nNote that this patch affects the following SoCs: Davinci, Samsung and\nOrion. Except for this last, the change is minor: irq_gc_ack() is just\nrenamed into irq_gc_ack_set_bit().\n\nFor the Orion SoCs, the edge GPIO interrupts support is currently\nbroken. irq_gc_ack() try to acknowledge a such interrupt by setting\nthe corresponding cause register bit. The Orion GPIO device expect the\nopposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used.\n\nTested on Network Space v2.\n\nReported-by: Joey Oravec \u003cjoravec@drewtech.com\u003e\nSigned-off-by: Simon Guinot \u003csguinot@lacie.com\u003e\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\n" }, { "commit": "13863a66c9c8a663665445cf05d68de96ff31830", "tree": "cb7864cf23b6f26f3eb11cfe09526eb7110a0e9a", "parents": [ "7f45e5cd1718ed769295033ca214032848a0097d" ], "author": { "name": "Jesper Juhl", "email": "jj@chaosbits.net", "time": "Thu Jun 09 23:14:58 2011 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Jun 10 10:53:42 2011 +0200" }, "message": "genirq: Prevent potential NULL dereference in irq_set_irq_wake()\n\nIn kernel/irq/manage.c::irq_set_irq_wake() we call\nirq_get_desc_buslock() which may return NULL, but the code\ndereferences the result unconditionally.\n\nirq_set_irq_wake() has lots of callers - I checked a few and I couldn\u0027t\nfind anything that guarantees that they won\u0027t call it with some input that\nwill cause irq_get_desc_buslock() to return NULL, so I think it\u0027s a good\nthing to test and -EINVAL was the most sane error code in this situation\nthat I could think of.\n\nNot all callers test the return value of irq_set_irq_wake(), but those\nthat do take !\u003d 0 to mean error as far as I can see, so they should be\nfine.
