From 4c4c9432a6c916729c7296c47fe93b053a73e20c Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@infradead.org>
Date: Tue, 29 Nov 2005 09:43:42 +0100
Subject: [PATCH] [PATCH] USB: mark various usb tables const

patch below marks various USB tables and variables as const so that they
end up in .rodata section and don't cacheline share with things that get
written to. For the non-array variables it also allows gcc to optimize
more.
