Subject: kexec: define kexec_in_progress in !CONFIG_KEXEC case
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2b94ed245861a7d378dcde6eef7fa7717e06e349;p=openwrt%2Fstaging%2Fblogic.git

kexec: define kexec_in_progress in !CONFIG_KEXEC case

If some piece of code wants to check kexec_in_progress it has to be put
in #ifdef CONFIG_KEXEC block to not break the build in !CONFIG_KEXEC
case. Overcome this limitation by defining kexec_in_progress to false.
