  "message": "[ARM] fixmap support\n\nThis is the minimum fixmap interface expected to be implemented by\narchitectures supporting highmem.\n\nWe have a second level page table already allocated and covering\n0xfff00000-0xffffffff because the exception vector page is located\nat 0xffff0000, and various cache tricks already use some entries above\n0xffff0000.  Therefore the PTEs covering 0xfff00000-0xfffeffff are free\nto be used.\n\nHowever the XScale cache flushing code already uses virtual addresses\nbetween 0xfffe0000 and 0xfffeffff.\n\nSo this reserves the 0xfff00000-0xfffdffff range for fixmap stuff.\n\nThe Documentation/arm/memory.txt information is updated accordingly,\nincluding the information about the actual top of DMA memory mapping\nregion which didn\u0027t match the code.\n\nSigned-off-by: Nicolas Pitre \u003cnico@marvell.com\u003e\n",
