From: Rui Salvaterra Date: Wed, 30 Dec 2020 20:04:42 +0000 (+0000) Subject: kernel-build: fix STRIP_KERNEL_EXPORTS for 64-bit kernels X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f3bfff9d7f85ab5f2df2728a760ddeebdb185f4c;p=openwrt%2Fstaging%2Fthess.git kernel-build: fix STRIP_KERNEL_EXPORTS for 64-bit kernels While parsing the nm output, we need to account for the fact that 64-bit kernels have 64-bit wide addresses. While at it, replace the grep | sed combo with a single awk invocation and a stronger regex.
