Subject: [PATCH] x86/head_64.S: remove unused L3_PAGE_OFFSET

The kernel/head_64.S has L3_PAGE_OFFSET definition which is not
used anywhere. It was introduced in the a6523748bd commit
(paravirt/x86, 64-bit: move __PAGE_OFFSET to leave a space for hypervisor
by Eduardo Habkost <ehabkost@...hat.com>), but still not used
anywhere.
