Subject: kern/dl: Use correct segment in grub_dl_set_mem_attrs()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d72208423dcabf9eb4a3bcb17b6b31888396bd49;p=thirdparty%2Fgrub.git

kern/dl: Use correct segment in grub_dl_set_mem_attrs()

The previous code would never actually call grub_update_mem_attrs()
as sh_info will always be zero for the sections that exist in memory.
