Subject: [PATCH v3 10/23] linux-user/m68k: Use force_sig_fault
Date: Wed,  3 Nov 2021 10:08:34 -0400	[thread overview]
Message-ID: <20211103140847.454070-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20211103140847.454070-1-richard.henderson@linaro.org>

Use the new function instead of setting up a target_siginfo_t
and calling queue_signal. Fill in the missing PC for SIGTRAP.
