Rodriguez" This v5 drops the addition of new early_param_*() helpers and their use on pat_enabled as we are sticking with __read_mostly, and as per review this should be selectively used only on well established hot paths. pat_enabled turns out to be a common hot path, so we want to keep that. This v5 also changes the pr_info() patch slightly to address the feedback. The other patches do not change at all. Luis R. Rodriguez (6): x86/mm/pat: use pr_info() and friends x86/mm/pat: redefine pat_enabled arch/x86/mm/pat: export pat_enabled() ivtv: use arch_phys_wc_add() and require PAT disabled IB/ipath: add counting for MTRR IB/ipath: use arch_phys_wc_add() and require PAT disabled arch/x86/include/asm/pat.h | 7 +-- arch/x86/kernel/cpu/mtrr/main.c | 2 +- arch/x86/mm/iomap_32.c | 2 +- arch/x86/mm/ioremap.c | 4 +- arch/x86/mm/pageattr.c | 2 +- arch/x86/mm/pat.c | 75 +++++++++++++-------------- arch/x86/mm/pat_internal.h | 2 +- arch/x86/mm/pat_rbtree.c | 5 +- arch/x86/pci/i386.c | 6 +-- drivers/infiniband/hw/ipath/Kconfig | 3 ++ drivers/infiniband/hw/ipath/ipath_driver.c | 18 +++++-- drivers/infiniband/hw/ipath/ipath_kernel.h | 4 +- drivers/infiniband/hw/ipath/ipath_wc_x86_64.c | 43 ++++----------- drivers/media/pci/ivtv/Kconfig | 3 ++ drivers/media/pci/ivtv/ivtvfb.c | 58 ++++++++------------- 15 files changed, 103 insertions(+), 131 deletions(-) -- 2.3.2.209.gd67f9d5.dirty -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
