* kernel-build: fix STRIP_KERNEL_EXPORTS for recent kernelsJohn Crispin2014-09-151-1/+1
| | | | | | | | | | Recent kernels started to mark exported symbols as global. Adapt expressions in kernel-build.mk to also match global symbols when grep'ing through nm output. Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 42555
* include: fix kernel download failure with git & local treesJohn Crispin2014-06-021-1/+1
| | | | | | | | | | | | | | | | | | When using the options EXTERNAL_KERNEL_TREE or KERNEL_GIT_CLONE_URI, the command "make downloads" fails as it tries to download the kernel tarball despite the option. This doesn't happen during a regular build as in that case, the dependency is conditionned through the LINUX_SITE variable, which is not set in these cases. Below is a snapshot of the error for an target using a 3.14 kernel: make[3]: *** No rule to make target `.../dl/linux-3.14.tar.xz', needed by `download'. Stop.

* build: speed up kernel symbol export strippingFelix Fietkau2013-12-141-3/+3
| | | | | | | | | | GNU grep has a high per-expression setup overhead when compiling regular expressions. Use -F to force it to interpret the input as fixed strings, which is much faster (fraction of a second instead of multiple minutes). Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 39049
* buildroot: build a second pass kernel if initramfs is enabledFlorian Fainelli2013-06-271-0/+1
| | | | | | | | | If initramfs is enabled, build a second pass kernel containing the CPIO rootfs, preliminary work to get non exclusive enabling of initramfs. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 37047
