The patch titled Subject: mm,x86,um: move CMPXCHG_DOUBLE config option has been removed from the -mm tree. Its filename was mmx86um-move-cmpxchg_double-config-option.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Heiko Carstens <heiko.carstens@xxxxxxxxxx> Subject: mm,x86,um: move CMPXCHG_DOUBLE config option Move CMPXCHG_DOUBLE and rename it to HAVE_CMPXCHG_DOUBLE so architectures can simply select the option if it is supported.
