  "message": "MIPS: Make TASK_SIZE reflect proper size for both 32 and 64 bit processes.\n\nThe TASK_SIZE macro should reflect the size of a user process virtual\naddress space.  Previously for 64-bit kernels, this was not the case.\nThe immediate cause of pain was in\nhugetlbfs/inode.c:hugetlb_get_unmapped_area() where 32-bit processes\ntrying to mmap a huge page would be served a page with an address\noutside of the 32-bit address range.  But there are other uses of\nTASK_SIZE in the kernel as well that would like an accurate value.\n\nThe new definition is nice because it now makes TASK_SIZE and\nTASK_SIZE_OF() yield the same value for any given process.\n\nFor 32-bit kernels there should be no change, although I did factor\nout some code in asm/processor.h that became identical for the 32-bit and\n64-bit cases.\n\n__UA_LIMIT is now set to ~((1 \u003c\u003c SEGBITS) - 1) for 64-bit kernels.\nThis should eliminate the possibility of getting a\nAddressErrorException in the kernel for addresses that pass the\naccess_ok() test.\n\nWith the patch applied, I can still run o32, n32 and n64 processes,\nand have an o32 shell fork/exec both n32 and n64 processes.\n\nSigned-off-by: David Daney \u003cddaney@caviumnetworks.com\u003e\nTo: linux-mips@linux-mips.org\nPatchwork: https://patchwork.linux-mips.org/patch/1701/\n",
