From 42b20995fae6318fd2e85ddbbaf7b4f7c3724e68 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 22 Jan 2021 12:02:51 +0100 Subject: [PATCH] MIPS: make kgdb depend on FPU support kgdb fails to build when the FPU support is disabled: arch/mips/kernel/kgdb.c: In function 'dbg_set_reg': arch/mips/kernel/kgdb.c:147:35: error: 'struct thread_struct' has no member named 'fpu' 147 | memcpy((void *)¤t->thread.fpu.fcr31, mem, | ^ arch/mips/kernel/kgdb.c:155:34: error: 'struct thread_struct' has no member named 'fpu' 155 | memcpy((void *)¤t->thread.fpu.fpr[fp_reg], mem, This is only relevant for CONFIG_EXPERT=y, so disallowing it in Kconfig is an easier workaround than fixing it properly.
