Subject: [PATCH 2/3] x86: delete EISA_VLB_PRIMING Kconfig option and code
There was one instance of a VLB card which would emulate
an EISA ID response ID when primed with a certain I/O
handshake.
Since (a) VLB was largely confined to 486 vintage motherboards
from the early/mid 1990s and (b) there was only one card that
needed this and (c) we are dropping EISA support from x86,
everything relating to this option can be removed w/o impacting
any other architectures that might be unwilling to drop EISA
support just yet.
