Subject: [S390] Kconfig: Select CONFIG_KEXEC for CONFIG_CRASH_DUMP
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=96603b505cb6c54782a27599afef65cc108ef5f2;p=deliverable%2Flinux.git

[S390] Kconfig: Select CONFIG_KEXEC for CONFIG_CRASH_DUMP

The kdump infrastructure is built on top of kexec. Therefore
CONFIG_KEXEC has to be enabled when CONFIG_CRASH_DUMP is selected.
