Subject: [ARM] remove useless setting of VM_RESERVED
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6d6a54d1e4c2c6fbccd128ab4e6c8817db124866;p=linux-beck.git

[ARM] remove useless setting of VM_RESERVED

remap_pfn_range() takes care of setting the appropriate VM_*
flags itself; there's no need for callers of remap_pfn_range()
to set VM_RESERVED before it is called.
