Hi Paul, Today's linux-next merge of the rcu tree got a conflict in arch/Kconfig between commit b952741c8079 ("cputime: Generalize CONFIG_VIRT_CPU_ACCOUNTING") from the tip tree and commit 3dbdfc26e27f ("rcu: Settle config for userspace extended quiescent state") from the rcu tree. Just context changes. I fixed it up (see below) and can carry the fix as necessary. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc arch/Kconfig index 07db929,1c7c9be..0000000 --- a/arch/Kconfig +++ b/arch/Kconfig @@@ -294,26 -274,14 +294,36 @@@ config SECCOMP_FILTE See Documentation/prctl/seccomp_filter.txt for details. +config HAVE_MOD_ARCH_SPECIFIC + bool + help + The arch uses struct mod_arch_specific to store data.
