+Subject: drm/amd/display: Use GFP_ATOMIC in dc_create_stream_for_sink
+
+From: Natalie Vock <natalie.vock@gmx.de>
+
+commit 28dfe4317541e57fe52f9a290394cd29c348228b upstream.
+
+This can be called while preemption is disabled, for example by
+dcn32_internal_validate_bw which is called with the FPU active.
+
+Fixes "BUG: scheduling while atomic" messages I encounter on my Navi31
+machine.

+Subject: net: stmmac: remove support for lpi_intr_o
+
+From: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
+
+commit 14eb64db8ff07b58a35b98375f446d9e20765674 upstream.
+
+The dwmac databook for v3.74a states that lpi_intr_o is a sideband
+signal which should be used to ungate the application clock, and this
+signal is synchronous to the receive clock. The receive clock can run
+at 2.5, 25 or 125MHz depending on the media speed, and can stop under
+the control of the link partner. This means that the time it takes to
+clear is dependent on the negotiated media speed, and thus can be 8,
+40, or 400ns after reading the LPI control and status register.
+
+It has been observed with some aggressive link partners, this clock
+can stop while lpi_intr_o is still asserted, meaning that the signal
+remains asserted for an indefinite period that the local system has
+no direct control over.
+
+The LPI interrupts will still be signalled through the main interrupt
+path in any case, and this path is not dependent on the receive clock.
+
+This, since we do not gate the application clock, and the chances of
+adding clock gating in the future are slim due to the clocks being
+ill-defined, lpi_intr_o serves no useful purpose. Remove the code which
+requests the interrupt, and all associated code.
