From: "Luis R. Rodriguez" <mcg...@suse.com> This provides a bit of clean up on PAT and then adds addresses the agreed upon compromise of how we will address drivers with broken PAT support by using pat_enabled() and recommending to boot with "nopat" kernel parameter.
With this and the rest of the easier changes submitted we should soon see a patch trickle down which buries MTRR from direct driver access. That will only be done once *all* the series addressing the conversion have been merged. The two driver changes that are implicated here have been reviewed by the respective maintainers, this goes with their respective ACKs. Luis R. Rodriguez (8): x86/mm/pat: use pr_info() and friends init.h: add __read_mostly to early_param_on_off() init.h: add early_param_on() and early_param_off() x86/mm/pat: use early_param_off() and 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 | 86 ++++++++++++--------------- 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 +++++++----------- include/linux/init.h | 25 +++++++- 14 files changed, 123 insertions(+), 140 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 majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
