11 * This file provides the glue to stick the processor-specific bits
12 * into the kernel in an efficient manner. The idea is to use branches
13 * when we're only targetting one class of TLB, or indirect calls
14 * when we're targetting multiple classes of TLBs.

32 * We have the following to choose from:
35 * v4_early - ARMv4 without Thumb early abort handler
36 * v4t_late - ARMv4 with Thumb late abort handler
37 * v4t_early - ARMv4 with Thumb early abort handler
38 * v5tej_early - ARMv5 with Thumb and Java early abort handler
39 * xscale - ARMv5 with Thumb with Xscale extensions
40 * v6_early - ARMv6 generic early abort handler
