[We\u0027ve not kernel.h for BUILD_BUG_ON.] Ugh -\n very confusing for someone who is new to kernel development.\n\n With the above in mind, the goals of this changeset are:\n\n 1) find and fix any include/*.h files that were relying on the\n implicit presence of BUG code.\n 2) find and fix any C files that were consuming kernel.h and hence\n relying on implicitly getting some/all BUG code.\n 3) Move the BUG related code living in kernel.h to \u003clinux/bug.h\u003e\n 4) remove the asm/bug.h from kernel.h to finally break the chain.\n\n During development, the order was more like 3-4, build-test, 1-2. But\n to ensure that git history for bisect doesn\u0027t get needless build\n failures introduced, the commits have been reorderd to fix the problem\n areas in advance.\n\n\t[1] https://lkml.org/lkml/2012/1/3/90\n\t[2] https://lkml.org/lkml/2012/1/17/414\"\n\nFix up conflicts (new radeon file, reiserfs header cleanups) as per Paul\nand linux-next.\n\n* tag \u0027bug-for-3.4\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:\n kernel.h: doesn\u0027t explicitly use bug.h, so don\u0027t include it.\n bug: consolidate BUILD_BUG_ON with other bug code\n BUG: headers with BUG/BUG_ON etc. need linux/bug.h\n bug.h: add include of it to various implicit C users\n lib: fix implicit users of kernel.h for TAINT_WARN\n spinlock: macroize assert_spin_locked to avoid bug.h dependency\n x86: relocate get/set debugreg fcns to include/asm/debugreg.\n" }, { "commit": "df7a3ee29b775edd1c2d75cf0b128b174bd4091e", "tree": "dd06376cb8f71b6914420c99b827baba3ce33867", "parents": [ "b9136d207f0c05c96c6b9c980fa7f7fd541a65a8" ], "author": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Sat Mar 24 09:18:57 2012 -0400" }, "committer": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Sat Mar 24 09:23:06 2012 -0400" }, "message": "xen/acpi: Fix Kconfig dependency on CPU_FREQ\n\nThe functions: \"acpi_processor_*\" sound like they depend on CONFIG_ACPI_PROCESSOR\nbut in reality they are exposed when CONFIG_CPU_FREQ\u003d[y|m].

There are already a number of filter flags in\n/proc/\u003cpid\u003e/coredump_filter, however, these allow one to specify \u0027types\u0027\nof kernel memory, not specific address ranges (which is needed in this\ncase).\n\nSince there are no more vma flags available, the first patch eliminates\nthe need for the \u0027VM_ALWAYSDUMP\u0027 flag. The flag is used internally by\nthe kernel to mark vdso and vsyscall pages. However, it is simple\nenough to check if a vma covers a vdso or vsyscall page without the need\nfor this flag.\n\nThe second patch then replaces the \u0027VM_ALWAYSDUMP\u0027 flag with a new\n\u0027VM_NODUMP\u0027 flag, which can be set by userspace using new madvise flags:\n\u0027MADV_DONTDUMP\u0027, and unset via \u0027MADV_DODUMP\u0027. The core dump filters\ncontinue to work the same as before unless \u0027MADV_DONTDUMP\u0027 is set on the\nregion.\n\nThe qemu code which implements this features is at:\n\n http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch\n\nIn my testing the qemu core dump shrunk from 383MB -\u003e 13MB with this\npatch.\n\nI also believe that the \u0027MADV_DONTDUMP\u0027 flag might be useful for\nsecurity sensitive apps, which might want to select which areas are\ndumped.\n\nThis patch:\n\nThe VM_ALWAYSDUMP flag is currently used by the coredump code to\nindicate that a vma is part of a vsyscall or vdso section. However, we\ncan determine if a vma is in one these sections by checking it against\nthe gate_vma and checking for a non-NULL return value from\narch_vma_name().

part of this change:\n\n1. As TWL RTC supports periodic interrupt, the correct event should be\n RTC_PF instead of RTC_UF.\n\n2. No need to initialize variable \"events\" to 0 \u0026 then OR it with the\n event values. Hence fixing it.\n\nSigned-off-by: Venu Byravarasu \u003cvbyravarasu@nvidia.com\u003e\nCc: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "94a339d016e26f96a1bd9e08306c857825c91a66", "tree": "1f1fcdfbb741b6821b2f26d1f4c0442e03ac3f3d", "parents": [ "f7439bcb74aca4234fedc336a21e169e6e33bb2e" ], "author": { "name": "Venu Byravarasu", "email": "vbyravarasu@nvidia.com", "time": "Fri Mar 23 15:02:33 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 23 16:58:39 2012 -0700" }, "message": "drivers/rtc/rtc-twl.c: simplify RTC interrupt clearing\n\nFor clearing RTC interrupt, programming ALARM bit only is sufficient, as\nall other bits are any way not affected by writing 0 to them.\n\nHence removed unwanted OR operation.\n\nSigned-off-by: Venu Byravarasu \u003cvbyravarasu@nvidia.com\u003e\nCc: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f7439bcb74aca4234fedc336a21e169e6e33bb2e", "tree": "815b214ea649e068711e5b36de3952f1221c717d", "parents": [ "ce9f650636d310e4c8febc821b0038e9918a12db" ], "author": { "name": "Venu Byravarasu", "email": "vbyravarasu@nvidia.com", "time": "Fri Mar 23 15:02:33 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 23 16:58:39 2012 -0700" }, "message": "drivers/rtc/rtc-twl.c: enable RTC irrespective of its prior state\n\nAs part of probe, before enabling RTC, RTC_CTRL register is read to check\nif it is already running.
