From 8db16d19111b33bda95f9f0ef02d814d8a49b023 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 7 May 2019 13:56:45 +0200 Subject: s390/boot: fix compiler error due to missing awk strtonum The strtonum awk function is a GNU extension and is not available with all versions of awk. The link of bzImage fails with this error message: >> awk: line 2: function or never defined >> awk: line 2: function strtonum never defined objcopy: --pad-to: bad number: arch/s390/boot/compressed/vmlinux Drop the awk script and the --pad-to objcopy parameter it generated and use a FILL pattern with an appropriate alignment in the linker script for the arch/s390/boot/compressed/vmlinux file.
