Subject: kernel/printk/printk.c: enable boot delay for earlyprintk
X-Git-Tag: accepted/tizen/common/20141203.182822~1142^2~162
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=29e9d22559065af169bba6f99166eb9ab64c01c6;p=platform%2Fkernel%2Flinux-arm64.git

kernel/printk/printk.c: enable boot delay for earlyprintk

boot_delay does not work for earlyprintk because the kernel cmdline
parsing is late.

Change to use early_param so early kernel messages can also be delayed.
