+Subject: efi: Allow EFI_MEMORY_XP and EFI_MEMORY_RO both to be cleared
+
+From: Heiner Kallweit <hkallweit1@gmail.com>
+
+[ Upstream commit 45add3cc99feaaf57d4b6f01d52d532c16a1caee ]
+
+UEFI spec 2.9, p.108, table 4-1 lists the scenario that both attributes
+are cleared with the description "No memory access protection is
+possible for Entry". So we can have valid entries where both attributes
+are cleared, so remove the check.

+Subject: efi: cper: fix snprintf() use in cper_dimm_err_location()
+
+From: Rasmus Villemoes <linux@rasmusvillemoes.dk>
+
+[ Upstream commit 942859d969de7f6f7f2659a79237a758b42782da ]
+
+snprintf() should be given the full buffer size, not one less. And it
+guarantees nul-termination, so doing it manually afterwards is
+pointless.
+
+It's even potentially harmful (though probably not in practice because
+CPER_REC_LEN is 256), due to the "return how much would have been
+written had the buffer been big enough" semantics. I.e., if the bank
+and/or device strings are long enough that the "DIMM location ..."
+output gets truncated, writing to msg[n] is a buffer overflow.

+[ Upstream commit 2a55ca37350171d9b43d561528f23d4130097255 ]
+
+zap_vma_ptes() is only available when CONFIG_MMU is set/enabled.
+Without CONFIG_MMU, vfio_pci.o has build errors, so make
+VFIO_PCI depend on MMU.

+Subject: vfio/platform: fix module_put call in error flow
+
+From: Max Gurtovoy <mgurtovoy@nvidia.com>
+
+[ Upstream commit dc51ff91cf2d1e9a2d941da483602f71d4a51472 ]
+
+The ->parent_module is the one that use in try_module_get. It should
+also be the one the we use in module_put during vfio_platform_open().
