Robert Richter 19514fc665 arm, kbuild: make "make install" not depend on vmlinux ... Install targets (install, zinstall, uinstall) on arm have a dependency to vmlinux. This may cause parts of the kernel to be rebuilt during installation. We must avoid this since this may run as root. Install targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus emphasized this in: http://lkml.org/lkml/2013/7/10/600 So on arm and maybe other archs we need the same as for x86: 1648e4f8 x86, kbuild: make "make install" not depend on vmlinux This patch fixes this for arm. Dependencies are removed and instead a check to install.sh is added for the files that are needed. This issue was uncovered by this build error where the -j option is used in conjunction with install targets: $ make <makeflags> $ make <makeflags> zinstall ... DEPMOD Usage: .../scripts/depmod.sh /sbin/depmod <kernelrelease> (INSTALL_MOD_PATH and INSTALL_PATH variables set, so no root perms required in this case.) The problem is that zinstall on arm due to its dependency to vmlinux does a prepare/prepare3 and finally does a forced rewrite of kernel.release even if it exists already. Rebuilding kernel.release removes it first and then recreates it. This might race with another parallel make job running depmod. So this patch should fix this one too. Also quoting $(KERNELRELEASE) arg for install.sh as this messes argument order in case it is empty (which is the case if the kernel was not built yet).
