Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: [NET] Eliminate user-selectable CONFIG_MV643XX_ETH_[012] [MIPS] Drop __init from init_8259A() [MIPS] Fix Kconfig typo bug [MIPS] Fix double signal on trap and break instruction [MIPS] sigset_32 has been made redundand by compat_sigset_t. [MIPS] emma2rh: Remove needless <asm/i8259.h> inclusion. [MIPS] Add MTD device support for Cobalt
