Subject: [PATCH 30/50] ppc/xive: Add xive_tctx_pipr_present() to present new interrupt
Date: Mon, 12 May 2025 13:10:39 +1000	[thread overview]
Message-ID: <20250512031100.439842-31-npiggin@gmail.com> (raw)
In-Reply-To: <20250512031100.439842-1-npiggin@gmail.com>

xive_tctx_pipr_update() is used for multiple things. In an effort
to make things simpler and less overloaded, split out the function
that is used to present a new interrupt to the tctx.
