Subject: [LTP] [PATCH] Fix mmap01 testcase on hppa architecture
Message-ID: <20170609145328.GA7129@ls3530>

The mmap() syscall to map a file at any given page-aligned address (via the
MAP_FIXED flag) can fail on the hppa architecture due to cache colouring
requirements of the architecture.

This patch drops the MAP_FIXED flag and thus maps the file instead at
some convenient address based on the hint as given by the addr
parameter. The tests covered by mmap01 check the *end* of the mmaped
file for consistency, so mapping the beginning of the file at any
address is okay without breaking the main intention of the mmap01
testcase.
