Subject: [PATCH] x86: remove unused efi_get_time function
Date: Fri, 17 Jun 2016 16:56:58 +0200	[thread overview]
Message-ID: <20160617145713.3737965-1-arnd@arndb.de> (raw)

Nothing calls the efi_get_time function on x86, but it does suffer
from the 32-bit time_t overflow in 2038.

This removes the function, we can always put it back in case we need
it later.
