* kernel: Support kernel options required by systemdJohn Crispin2015-03-211-6/+28
| | | | | | | | | | | | | These kernel options are all likely to be widely useful in this modern age, but are immediately useful for systemd support. c.f. http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-apps/systemd/systemd-9999.ebuild?&view=markup#l118 Adapted from a patch by Adam Porter.

* kernel: enable open by fhandle syscallsJohn Crispin2015-03-151-0/+6
| | | | | | | | | | | | | | | | | | | | This is needed by many services to function properly and as all modern distributions got it enabled, it starts to be a de-facto standard, i.e. user-space starts to silently depend on it. This also pulls in EXPORTFS, however, the kernel binary size increases only a little. On ARM systems comes down to 800 bytes uncompressed and about 200 bytes compressed size. On MIPS systems it's about 1.2 kB size increase of the LZMA compressed kernel. v2: use menuconfig option instead of just enabling the option Signed-off-by: Daniel Golle <daniel@makrotopia.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@44765 3c298f89-4303-0410-b956-a3cf2f4a3e73

| | | | | | | | | | | | | This change does multiple things, all related to enable sparse usage as a static analysis tool selectable from the OpenWrt configuration: *add a KERNEL_SPARSE option in the config to add sparse to the kernel build (through the C=1 option usage) *add sparse as a new host tools. It will get selected automatically when the above option will be enabled Signed-off-by: Mathieu Olivari <mathieu@qca.qualcomm.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@40490 3c298f89-4303-0410-b956-a3cf2f4a3e73
