x86/kexec: Make variable static and config dependent The following sparse warning is emitted: arch/x86/kernel/crash.c:59:15: warning: symbol 'crash_zero_bytes' was not declared. Should it be static? The variable is only used in this compilation unit, but it is also only used when CONFIG_KEXEC_FILE is enabled. Just making it static would result in a 'defined but not used' warning for CONFIG_KEXEC_FILE=n. Make it static and move it into the existing CONFIG_KEXEC_FILE section. [ tglx: Massaged changelog and moved it into the existing ifdef ] Fixes: dd5f726076cc ("kexec: support for kexec on panic using new system call") Signed-off-by: Tiezhu Yang <kernelpatch@126.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Dave Young <dyoung@redhat.com> Cc: bp@alien8.de Cc: hpa@zytor.com Cc: kexec@lists.infradead.org Cc: vgoyal@redhat.com Cc: Vivek Goyal <vgoyal@redhat.com> Link: https://lkml.kernel.org/r/117ef0c6.3d30.16b87c9cfbf.Coremail.kernelpatch@126.com
