Changelog: [ia64] platform_kernel_launch_event is a noop in non-SN kernel


BZ 232657

http://git.kernel.org/?p=linux/kernel/git/aegl/linux-2.6.git;a=commit;h=6a3d039078b337856bd3cfa436be3b1b223440a5

[PATCH] ia64: platform_kernel_launch_event is noop on generic kernel

Add a missing #define for the platform_kernel_launch_event.  Without this
fix, a call to platform_kernel_launch_event() becomes a noop on generic
kernels.  SN systems require this fix to successfully kdump/kexec from
certain hardware errors.

It is NOT tested by me, but t looks good to me, and need to go into RHEL 
5.1.
Please  ACK.

Thanks,
Luming
