From 59351365ac271b5e0eb180f211c531476a36221f Mon Sep 17 00:00:00 2001 From: "Lorenzo Stoakes (ARM)" Date: Tue, 8 Sep 2026 21:55:02 +0100 Subject: [PATCH] scripts/mksysmap: fix escape of '$' in the __pi_ pattern Commit b18b047002b7 ("kbuild: change scripts/mksysmap into sed script") converted scripts/mksysmap from a shell script to a sed script. However an error was made - escaping of '$' required \\ escaping in shell but only \ in a sed script. This was mostly corrected in commit 7a6c355b55c0 ("scripts/mksysmap: Fix escape chars '$'"), but this fix missed arm64 PIE namespace local symbols like __pi_$x and __pi_$d which appear in System.map and /proc/kallsyms: $ grep __pi_\\$ /proc/kallsyms | sort -u 0000000000000000 d __pi_$d 0000000000000000 t __pi_$x Fix the escaping properly.
