X-Git-Tag: v3.13-rc1~78^2~11
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c920745e6964bd4b9315a17b018d83fad66010d3;p=pandora-kernel.git

sparc64: Clean up 64-bit mmap exclusion defines.

Older UltraSPARC chips had an address space hole due to the MMU only
supporting 44-bit virtual addresses.

The top end of this hole also has the same value as the current
definition of PAGE_OFFSET, so this can be confusing.

Consolidate the defines for the userspace mmap exclusion range into
page_64.h and use them in sys_sparc_64.c and hugetlbpage.c
