Subject[PATCH 5.0 14/46] staging: android: ion: fix sys heap pools gfp_flags
Date
5.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Qing Xia <saberlily.xia@hisilicon.com>

commit 9bcf065e28122588a6cbee08cf847826dacbb438 upstream.

In the first loop, gfp_flags will be modified to high_order_gfp_flags,
and there will be no chance to change back to low_order_gfp_flags.

Fixes: e7f63771b60e ("ION: Sys_heap: Add cached pool to spead up cached buffer alloc")
