perf: Disable perf for ARC770 only, enable for ARC HS38

2017-05-10T22:53:05Z

Toolchain built for ARCv1 (read for ARC700 cores) by default has disabled atomic ops (-mno-atomic). When we build Linux kernel for ARC770 which has LL/SC instructions and thus may handle normally atomic ops we explicitly add "-matomic" in CFLAGS. But since user-space perf utility has no way to extract CPU config options from Kconfig/defconfig it uses compiler default settings. In case of ARCv2 (read ARC HS38) atomics are enabled by default and so perf builds perfectly fine thus reenabling perf for ARC HS38 (actually for non-ARC700 targets). Signed-off-by: Alexey Brodkin

build: new fixes for symlinked .config handling

2017-05-10T22:53:05Z

When running "make {config|defconfig|oldconfig}" with symlinked .config (e.g. to env/.config) it renames symlink to .config.old, creates new .config file, and writes the updated configuration into it. This breaks the desired workflow when changes in the configuration can be checked using "scripts/env diff" and commited using "scripts/env save". Since the env/.config file is not updated. The things become even worse when working with feeds, since feeds script quite often silently invokes "make {oldconfig|defconfig}" and breaks the symlink. Fix this issue by exporting KCONFIG_OVERWRITECONFIG=1, which forces mconf to overwrite the .config content, instead of renaming it and creating a new file. This variable is set only if .config is a symlink, otherwise the variable is not exported and the old behaviour is preserved. This change uses the same behaviour as "make menucofig", which has already been fixed in commit 5bf98b1acc3b6b178f8954c5075a58e1e6a99d6a. Also make a tiny cosmetic update to the "make menuconfig" target code layout to make it look like other config handling targets. Signed-off-by: Sergey Ryazanov

dnsmasq: don't propagate DUID from one host to another

If no DUID is set for a host, it should be empty, not the last one set for a previous host. Signed-off-by: Arjen de Korte
