+Subject: PCI: Call Max Payload Size-related fixup quirks early
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Marek Behún <kabel@kernel.org>
+
+commit b8da302e2955fe4d41eb9d48199242674d77dbe0 upstream.
+
+pci_device_add() calls HEADER fixups after pci_configure_device(), which
+configures Max Payload Size.
+
+Convert MPS-related fixups to EARLY fixups so pci_configure_mps() takes
+them into account.
+
+Fixes: 27d868b5e6cfa ("PCI: Set MPS to match upstream bridge")

+Subject: x86/reboot: Limit Dell Optiplex 990 quirk to early BIOS versions
+
+From: Paul Gortmaker <paul.gortmaker@windriver.com>
+
+commit a729691b541f6e63043beae72e635635abe5dc09 upstream.
+
+When this platform was relatively new in November 2011, with early BIOS
+revisions, a reboot quirk was added in commit 6be30bb7d750 ("x86/reboot:
+Blacklist Dell OptiPlex 990 known to require PCI reboot")
+
+However, this quirk (and several others) are open-ended to all BIOS
+versions and left no automatic expiry if/when the system BIOS fixed the
+issue, meaning that nobody is likely to come along and re-test.
+
+What is really problematic with using PCI reboot as this quirk does, is
+that it causes this platform to do a full power down, wait one second,
+and then power back on. This is less than ideal if one is using it for
+boot testing and/or bisecting kernels when legacy rotating hard disks
+are installed.
+
+It was only by chance that the quirk was noticed in dmesg - and when
+disabled it turned out that it wasn't required anymore (BIOS A24), and a
+default reboot would work fine without the "harshness" of power cycling the
+machine (and disks) down and up like the PCI reboot does.
+
+Doing a bit more research, it seems that the "newest" BIOS for which the
+issue was reported[1] was version A06, however Dell[2] seemed to suggest
+only up to and including version A05, with the A06 having a large number of
+fixes[3] listed.
+
+As is typical with a new platform, the initial BIOS updates come frequently
+and then taper off (and in this case, with a revival for CPU CVEs); a
+search for O990-A<ver>.exe reveals the following dates:
+
+ A02 16 Mar 2011
+ A03 11 May 2011
+ A06 14 Sep 2011
+ A07 24 Oct 2011
+ A10 08 Dec 2011
+ A14 06 Sep 2012
+ A16 15 Oct 2012
+ A18 30 Sep 2013
+ A19 23 Sep 2015
+ A20 02 Jun 2017
+ A23 07 Mar 2018
+ A24 21 Aug 2018
+
+While it's overkill to flash and test each of the above, it would seem
+likely that the issue was contained within A0x BIOS versions, given the
+dates above and the dates of issue reports[4] from distros. So rather than
+just throw out the quirk entirely, limit the scope to just those early BIOS
+versions, in case people are still running systems from 2011 with the
+original as-shipped early A0x BIOS versions.

+
+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit cbf286e8ef8337308c259ff5b9ce2e74d403be5a upstream.
+
+Removes static char buffer usage in the following decode functions:
+ xhci_decode_trb()
+ xhci_decode_ptortsc()
+
+Caller must provide a buffer to use.
+In tracing use __get_str() as recommended to pass buffer.
+
+Minor chanes are needed in xhci debugfs code as these functions are also
+used there. Changes include moving XHCI_MSG_MAX definititon from
+xhci-trace.h to xhci.h
