Subject: s390/ipl: avoid usage of __section(.data)
X-Git-Tag: 4.16-minor-rc-SMB3-fixes~42^2~9
X-Git-Url: http://git.samba.org/samba.git/?a=commitdiff_plain;h=c50ce358bd33df163f8ea347c8fe50abec14dc21;p=sfrench%2Fcifs-2.6.git

s390/ipl: avoid usage of __section(.data)

bss section is cleared before ipl.c code is called or global variables
are used nowadays. Remove stale comment and __section(.data) from
few global variables.

Also removes static/global variables initialization to 0.
