Subject: [RHEL7 PATCH 12/31] tests: brk-near-huge: Fix next chunk computation
|
|
|
fc9b0e |
for powerpc64
|
|
|
fc9b0e |
|
|
|
fc9b0e |
For powerpc64, the use of slices applies only to Hash MMU.
|
|
|
fc9b0e |
Hence, when determining the next chunk size, ensure that
|
|
|
fc9b0e |
the address is aligned to the slice size for Hash MMU and
|
|
|
fc9b0e |
the huge page size otherwise.
