Subject: [PATCH v4 4/5] powerpc/inst: Move ppc_inst_t definition in asm/reg.h
Date: Mon, 29 Nov 2021 12:53:04 +0100	[thread overview]
Message-ID: <7a63cb77d8ed7345e26ea8fab8e2472987632de5.1638186774.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <97a171efd8c582e2bae82c31f2a9519823a20d3f.1638186773.git.christophe.leroy@csgroup.eu>

Because of circular inclusion of asm/hw_breakpoint.h, we
need to move definition of asm/reg.h outside of inst.h
so that asm/hw_breakpoint.h gets it without including
asm/inst.h

Also remove asm/inst.h from asm/uprobes.h as it's not
needed anymore.
