From bc89690f6e2c80e100b4dbfbabc7c7adb8218d74 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Wed, 2 Jan 2019 16:32:35 +0100 Subject: [PATCH] gdb: The signal definitions of musl and gdb collide This fixes compilation of gdb on arm64. The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc defines it in signal.h, which collides. Kernel 4.14 misses the definitions of struct user_sve_header so we still have to use the aarch64-sve-linux-sigcontext.h header file which also provides that and make sure aarch64-sve-linux-sigcontext.h does not provide the same headers as the kernel or musl.
