[Why]

New GCC warnings for stringop-truncation and stringop-overflow help
catch common misuse of strncpy. This patch suppresses these warnings
by fixing bugs identified by them.

[How]

Since the parameter passed for name in amdpgu_dm_create_common_mode has
no fixed length, if the string is >= DRM_DISPLAY_MODE_LEN then
mode->name will not be null-terminated.

The truncation in fill_audio_info won't actually occur (and the string
will be null-terminated since the buffer is initialized to zero), but
the warning can be suppressed by using the proper buffer size.

This patch fixes both issues by using the real size for the buffer and
making use of strscpy (which always terminates).

SoCs that contain MDP5 have a top level wrapper called MDSS that
manages locks, power and irq for the sub-blocks within it.

Irq for HDMI is also routed through the MDSS.

Shortly after the Hot Plug Detection (HPD) is enabled in HDMI,
HDMI interrupts are recieved by the MDSS interrupt handler.
However at this moment the HDMI irq is still not mapped to
the MDSS irq domain so the HDMI irq handler cannot be called
to process the interrupts.

This leads to a flood of HDMI interrupts on CPU 0.

If we are lucky to have the HDMI initialization running on a
different CPU, it will eventually map the HDMI irq to MDSS irq
domain, the next HDMI interrupt will be handled by the HDMI irq
handler, the interrupt flood will stop and we will recover.

If the HDMI initialization is running on CPU 0, then it cannot
complete and there is nothing to stop the interrupt flood on
CPU 0. The system is stuck.

Fix this by moving the HPD enablement after the HDMI irq is
mapped to the MDSS irq domain.

The DSI encoder sets dssdev->ops->dsi.set_config, which is stored at the
same offset as dssdev->ops->hdmi.set_hdmi_mode. The code in omap_encoder
only checks if dssdev->ops->hdmi.set_hdmi_mode is NULL. Due to the way
union works, it won't be NULL if dsi.set_config is set. This means
dsi_set_config will be called with config=hdmi_mode=false=NULL parameter
resulting in a NULL dereference. Also the dereference happens while
console is locked, so kernel hangs without any debug output without
"fb.lockless_register_fb=1" parameter.

This restructures the code, so that the HDMI mode is only configured
for HDMI output types.

panel-dpi used to convey the bus-flags via the videomode, but recent
changes changed the use of videomode to DRM's drm_display_mode which
does not contain bus-flags. This broke panel-dpi, which didn't
explicitly store the bus-flags into dssdev->bus_flags.

Fix this by setting dssdev->bus_flags. Also change the bus_flags type to
u32, as that is the type used in the DRM framework, and we would get a
warning with drm_bus_flags_from_videomode() otherwise.

     attempt

   - Disable STIBP automatically when SMT is disabled

   - Optimize the switch_to() logic to avoid MSR writes and invocations
     of __switch_to_xtra().

   - Make the asynchronous speculation TIF updates synchronous to
     prevent stale mitigation state.

  As a general cleanup this also makes retpoline directly depend on

incorrect test of PCI_EXP_LNKCAP_SLS as a bitmask.  5d9a6330, which
