At the moment, the only\ndriver here is irq-bcm2835, the driver for the irq controller found in\nthe ARM BCM2835 SoC, present in Rasberry Pi systems. This irq\ncontroller driver was exporting its initialization function and its\nirq handling function through a header file in\n\u003clinux/irqchip/bcm2835.h\u003e.\n\nWhen proposing to also move another irq controller driver in\ndrivers/irqchip, Rob Herring raised the very valid point that moving\nthings to drivers/irqchip was good in order to remove more stuff from\narch/arm, but if it means adding gazillions of headers files in\ninclude/linux/irqchip/, it would not be very nice.\n\nSo, upon the suggestion of Rob Herring and Arnd Bergmann, this commit\nintroduces a small infrastructure that defines a central\nirqchip_init() function in drivers/irqchip/irqchip.c, which is meant\nto be called as the -\u003einit_irq() callback of ARM platforms. This\nfunction calls of_irq_init() with an array of match strings and init\nfunctions generated from a special linker section.\n\nNote that the irq controller driver initialization function is\nresponsible for setting the global handle_arch_irq() variable, so that\nARM platforms no longer have to define the -\u003ehandle_irq field in their\nDT_MACHINE structure.\n\nA global header, \u003clinux/irqchip.h\u003e is also added to expose the single\nirqchip_init() function to the reset of the kernel.\n\nA further commit moves the BCM2835 irq controller driver to this new\nsmall infrastructure, therefore removing the include/linux/irqchip/\ndirectory.\n\nSigned-off-by: Thomas Petazzoni \u003cthomas.petazzoni@free-electrons.com\u003e\nReviewed-by: Stephen Warren \u003cswarren@wwwdotorg.org\u003e\nReviewed-by: Rob Herring \u003crob.herring@calxeda.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\n[rob.herring: reword commit message to reflect use of linker sections.]\nSigned-off-by: Rob Herring \u003crob.herring@calxeda.com\u003e\n" }, { "commit": "ae278a935f086775e8ae31a8ec9f7224ea25ea3c", "tree": "efd3d6d7c29271af8acb283b2cc8ffd6dc39570b", "parents": [ "6bb27d7349db51b50c40534710fe164ca0d58902" ], "author": { "name": "Stephen Warren", "email": "swarren@nvidia.com", "time": "Mon Nov 19 16:41:20 2012 -0700" }, "committer": { "name": "Stephen Warren", "email": "swarren@nvidia.com", "time": "Wed Jan 02 11:07:43 2013 -0700" }, "message": "clocksource: add common of_clksrc_init() function\n\nIt is desirable to move all clocksource drivers to drivers/clocksource,\nyet each requires its own initialization function.

Two structures in the\nsame file may be placed awkwardly, because gcc has no clue that they\nare suppose to be in an array.\n\nA hack was used previous to force the alignment to 4, to pack the\nstructures together. But this caused alignment issues with other\narchitectures (sparc).\n\nInstead of packing the structures into an array, the structures\u0027 addresses\nare now put into the _ftrace_event section. As pointers are always the\nnatural alignment, gcc should always pack them tightly together\n(otherwise initcall, extable, etc would also fail).\n\nBy having the pointers to the structures in the section, we can still\niterate the trace_events without causing unnecessary alignment problems\nwith other architectures, or depending on the current behaviour of\ngcc that will likely change in the future just to tick us kernel developers\noff a little more.\n\nThe _ftrace_event section is also moved into the .init.data section\nas it is now only needed at boot up.\n\nSuggested-by: David Miller \u003cdavem@davemloft.net\u003e\nCc: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: David S.

We should switch the macro in the linker script to\nINIT_TASK_DATA. (Sorry that I missed this in reviewing the patch). Since\nthe macros are new, there is only one user of the INIT_TASK in\nvmlinux.lds.h, arch/mn10300/kernel/vmlinux.lds.S.\n\nHowever, we are currently using INIT_TASK_DATA for laying down an entire\n.data.init_task section. So rename that to INIT_TASK_DATA_SECTION.\n\nI would be worried about changing the meaning of INIT_TASK_DATA, but the\nold INIT_TASK_DATA implementation had no users, and in fact if anyone had\ntried to use it, it would have failed to compile because it didn\u0027t pass\nthe alignment to the old INIT_TASK.\n\nSigned-off-by: Tim Abbott \u003ctabbott@ksplice.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Jesper Nilsson \u003cJesper.Nilsson@axis.com\nSigned-off-by: Sam Ravnborg \u003csam@ravnborg.org\u003e\n" }, { "commit": "73f1d9391a6aa72efdcea2f302ee7bfcd313c631", "tree": "44824c45de7a3ceaa9a07cc0ecc2aeb29e321f37", "parents": [ "4075ea8c54a7506844a69f674990241e7766357b" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Wed Jun 24 01:04:36 2009 +0900" }, "committer": { "name": "Sam Ravnborg", "email": "sam@ravnborg.org", "time": "Fri Jun 26 23:55:27 2009 +0200" }, "message": "asm-generic/vmlinux.lds.h: Fix up RW_DATA_SECTION definition.\n\nRW_DATA_SECTION is defined to take 4 different alignment parameters,\nwhile NOSAVE_DATA currently uses a fixed PAGE_SIZE alignment as noted\nin the comments.\n\nThere are presently no in-tree users of this at present, and I just\nstumbled across this while implementing the simplified script on a new\narchitecture port, which subsequently resulted in a syntax error.\n\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nSigned-off-by: Sam Ravnborg \u003csam@ravnborg.org\u003e\n" }, { "commit": "405d967dc70002991f8fc35c20e0d3cbc7614f63", "tree": "ace31796327e9035488310d42e06acbab3a28656", "parents": [ "e74e396204bfcb67570ba4517b08f5918e69afea" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Wed Jun 24 15:13:38 2009 +0900" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Wed Jun 24 15:13:38 2009 +0900" }, "message": "linker script: throw away .discard section\n\nx86 throws away .discard section but no other archs do.
