  "message": "[POWERPC] Use 1TB segments\n\nThis makes the kernel use 1TB segments for all kernel mappings and for\nuser addresses of 1TB and above, on machines which support them\n(currently POWER5+, POWER6 and PA6T).\n\nWe detect that the machine supports 1TB segments by looking at the\nibm,processor-segment-sizes property in the device tree.\n\nWe don\u0027t currently use 1TB segments for user addresses \u003c 1T, since\nthat would effectively prevent 32-bit processes from using huge pages\nunless we also had a way to revert to using 256MB segments.  That\nwould be possible but would involve extra complications (such as\nkeeping track of which segment size was used when HPTEs were inserted)\nand is not addressed here.\n\nParts of this patch were originally written by Ben Herrenschmidt.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n",
