From 4c4c9432a6c916729c7296c47fe93b053a73e20c Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Tue, 29 Nov 2005 09:43:42 +0100 Subject: [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.
