Remove the unneded declaration for a kexec_load() routine. Fixes errors like these when running 'make headers_check': include/uapi/linux/kexec.h: userspace cannot reference function or variable defined in the kernel Paul said: : The kexec_load declaration isn't very useful for userspace, see the patch : I submitted in http://lkml.kernel.org/r/1389791824.17407.9.camel@x220 . : And After my attempt the export of that declaration has also been : discussed in : http://lkml.kernel.org/r/115373b6ac68ee7a305975896e1c4971e8e51d4c.1408731991.git.geoff@infradead.org : : In that last discussion no one has been able to point to an actual user of : it. So, as far as I can tell, no one actually uses it. Which makes : sense, because including this header by itself doesn't give one access to : a useful definition of kexec_load. So why bother with the declaration? Signed-off-by: Geoff Levand <geoff@infradead.org> Acked-by: Paul Bolle <pebolle@tiscali.nl> Cc: H.
