Jonathan Corbet 20613f24bc usbcore: cdev lock_kernel() pushdown
usb_open() is protected by a down_read(&minor_rwsem), but I'm not sure I
trust it to protect everything including subsidiary open() functions.

Geert Uytterhoeven 52de114e35 m68k: Prefix ISA type with ISA_TYPE_

(e.g. with `AMIGAHW_DECLARE(GG2_ISA)' in <asm/amigahw.h>) for some kernel
configurations. Use ISA_TYPE_* to avoid such conflicts.
