+Subject: drm/radeon: add a force flush to delay work when radeon
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+From: Zhenneng Li <lizhenneng@kylinos.cn>
+
+[ Upstream commit f461950fdc374a3ada5a63c669d997de4600dffe ]
+
+Although radeon card fence and wait for gpu to finish processing current batch rings,
+there is still a corner case that radeon lockup work queue may not be fully flushed,
+and meanwhile the radeon_suspend_kms() function has called pci_set_power_state() to
+put device in D3hot state.
+Per PCI spec rev 4.0 on 5.3.1.4.1 D3hot State.
+> Configuration and Message requests are the only TLPs accepted by a Function in
+> the D3hot state. All other received Requests must be handled as Unsupported Requests,
+> and all received Completions may optionally be handled as Unexpected Completions.
+This issue will happen in following logs:

+Subject: parisc: Add runtime check to prevent PA2.0 kernels on PA1.x machines
+
+From: Helge Deller <deller@gmx.de>
+
+[ Upstream commit 591d2108f3abc4db9f9073cae37cf3591fd250d6 ]
+
+If a 32-bit kernel was compiled for PA2.0 CPUs, it won't be able to run
+on machines with PA1.x CPUs. Add a check and bail out early if a PA1.x
+machine is detected.
