39 * Atheros Hardware Access Layer (HAL) OS Dependent Definitions.
43 * Starting with 2.6.4 the kernel supports a configuration option
44 * to pass parameters in registers. If this is enabled we must
45 * mark all function interfaces in+out of the HAL to pass parameters
46 * on the stack as this is the convention used internally (for
47 * maximum portability).
49 * XXX A lot of functions have __ahdecl in their definition but not declaration
51 * Since This is only an issue for i386 which has regparam enabled, instead of
52 * changing the vanilla FC3 kernel, for now, remove the regparm
