s390: set KEXEC_ARCH_S390 in arch_compat_trampoline
Set KEXEC_ARCH_S390 in order to make sure that kexec works also in compat
mode on s390.
Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
Extra Information from Eric Biederman
If you call sys_kexec_load in compat mode, you are required to pass
the architecture your kernel is actually running. The kexec kernel
code only supports one switching to one mode. So a 32bit user space
must be prepared to accept a 64bit handoff. The flag reports
that you can do that.
