+Subject: ACPI / PCI: Fix sysfs acpi_index and label errors
+
+From: Simone Gotti <simone.gotti@gmail.com>
+
+commit dcfa9be83866e28fcb8b7e22b4eeb4ba63bd3174 upstream.
+
+Fix errors in handling "device label" _DSM return values.
+
+If _DSM returns a Unicode string, the ACPI type is ACPI_TYPE_BUFFER, not
+ACPI_TYPE_STRING.  Fix dsm_label_utf16s_to_utf8s() to convert UTF-16 from
+acpi_object->buffer instead of acpi_object->string.
+
+Prior to v3.14, we accepted Unicode labels (ACPI_TYPE_BUFFER return
+values).  But after 1d0fcef73283, we accepted only ASCII (ACPI_TYPE_STRING)
+(and we incorrectly tried to convert those ASCII labels from UTF-16 to
+UTF-8).
+
+Rejecting Unicode labels made us return -EPERM when reading sysfs
+"acpi_index" or "label" files, which in turn caused on-board network
+interfaces on a Dell PowerEdge E420 to be renamed (by udev net_id internal)
+from eno1/eno2 to enp2s0f0/enp2s0f1.
+
+Fix this by accepting either ACPI_TYPE_STRING (and treating it as ASCII) or
+ACPI_TYPE_BUFFER (and converting from UTF-16 to UTF-8).

+commit 28e134464734 "[SCSI] hpsa: enable unit attention reporting"
+turns on unit attention notifications, but got the change wrong for
+all architectures other than x86, which now store an uninitialized
+value into the device register.
+
+Gcc helpfully warns about this:
+
+../drivers/scsi/hpsa.c: In function 'hpsa_set_driver_support_bits':
+../drivers/scsi/hpsa.c:6373:17: warning: 'driver_support' is used uninitialized in this function [-Wuninitialized]
+  driver_support |= ENABLE_UNIT_ATTN;
+                 ^
+
+This moves the #ifdef so only the prefetch-enable is conditional
+on x86, not also reading the initial register contents.

+Subject: PCI: Configure ASPM when enabling device
+
+From: Vidya Sagar <sagar.tv@gmail.com>
+
+commit 1f6ae47ecff7f23da73417e068018b311f3b5583 upstream.
+
+We can't do ASPM configuration at enumeration-time because enabling it
+makes some defective hardware unresponsive, even if ASPM is disabled later
+(see 41cd766b0659 ("PCI: Don't enable aspm before drivers have had a chance
+to veto it").  Therefore, we have to do it after a driver claims the
+device.
+
+We previously configured ASPM in pci_set_power_state(), but that's not a
+very good place because it's not really related to setting the PCI device
+power state, and doing it there means:
+
+  - We incorrectly skipped ASPM config when setting a device that's
+    already in D0 to D0.
+
+  - We unnecessarily configured ASPM when setting a device to a low-power
+    state (the ASPM feature only applies when the device is in D0).
+
+  - We unnecessarily configured ASPM when called from a .resume() method
+    (ASPM configuration needs to be restored during resume, but
+    pci_restore_pcie_state() should already do this).
+
+Move ASPM configuration from pci_set_power_state() to
+do_pci_enable_device() so we do it when a driver enables a device.

+Subject: powerpc/pci: Reorder pci bus/bridge unregistration during PHB removal
+
+From: Tyrel Datwyler <tyreld@linux.vnet.ibm.com>
+
+commit 7340056567e32b2c9d3554eb146e1977c93da116 upstream.
+
+Commit bcdde7e made __sysfs_remove_dir() recursive and introduced a BUG_ON
+during PHB removal while attempting to delete the power managment attribute
+group of the bus. This is a result of tearing the bridge and bus devices down
+out of order in remove_phb_dynamic. Since, the the bus resides below the bridge
+in the sysfs device tree it should be torn down first.
+
+This patch simply moves the device_unregister call for the PHB bridge device
+after the device_unregister call for the PHB bus.

+
+commit a32305bf90a2ae0e6a9a93370c7616565f75e15a upstream.
+
+powerpc defines various machine-specific routines for handling
+pci_set_dma_mask().  The routines for machine "PowerNV" may neglect
+to set dev->dma_mask.  This could confuse anyone (e.g. drivers) that
+consult dev->dma_mask to find the current mask.  Set the dma_mask in
+the PowerNV leaf routine.

+Subject: x86: don't exclude low BIOS area when allocating address space for non-PCI cards
+
+From: Christoph Schulz <develop@kristov.de>
+
+commit cbace46a9710a480cae51e4611697df5de41713e upstream.
+
+Commit 30919b0bf356 ("x86: avoid low BIOS area when allocating address
+space") moved the test for resource allocations that fall within the first
+1MB of address space from the PCI-specific path to a generic path, such
+that all resource allocations will avoid this area.  However, this breaks
+ISA cards which need to allocate a memory region within the first 1MB.  An
+example is the i82365 PCMCIA controller and derivatives like the Ricoh
+RF5C296/396 which map part of the PCMCIA socket memory address space into
+the first 1MB of system memory address space.  They do not work anymore as
+no usable memory region exists due to this change:

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Matt Fleming <matt.fleming@intel.com>
+
+commit 7b2a583afb4ab894f78bc0f8bd136e96b6499a7e upstream.
+
+Without CONFIG_RELOCATABLE the early boot code will decompress the
+kernel to LOAD_PHYSICAL_ADDR. While this may have been fine in the BIOS
+days, that isn't going to fly with UEFI since parts of the firmware
+code/data may be located at LOAD_PHYSICAL_ADDR.
+
+Straying outside of the bounds of the regions we've explicitly requested
+from the firmware will cause all sorts of trouble. Bruno reports that
+his machine resets while trying to decompress the kernel image.
+
+We already go to great pains to ensure the kernel is loaded into a
+suitably aligned buffer, it's just that the address isn't necessarily
+LOAD_PHYSICAL_ADDR, because we can't guarantee that address isn't in-use
+by the firmware.
+
+Explicitly enforce CONFIG_RELOCATABLE for the EFI boot stub, so that we
+can load the kernel at any address with the correct alignment.

+Subject: x86/xen: resume timer irqs early
+
+From: David Vrabel <david.vrabel@citrix.com>
+
+commit 8d5999df35314607c38fbd6bdd709e25c3a4eeab upstream.
+
+If the timer irqs are resumed during device resume it is possible in
+certain circumstances for the resume to hang early on, before device
+interrupts are resumed.  For an Ubuntu 14.04 PVHVM guest this would
+occur in ~0.5% of resume attempts.
+
+It is not entirely clear what is occuring the point of the hang but I
+think a task necessary for the resume calls schedule_timeout(),
+waiting for a timer interrupt (which never arrives).  This failure may
+require specific tasks to be running on the other VCPUs to trigger
+(processes are not frozen during a suspend/resume if PREEMPT is
+disabled).
+
+Add IRQF_EARLY_RESUME to the timer interrupts so they are resumed in
+syscore_resume().

+Subject: x86/xen: use vmap() to map grant table pages in PVH guests
+
+From: David Vrabel <david.vrabel@citrix.com>
+
+commit 7d951f3ccb0308c95bf76d5eef9886dea35a7013 upstream.
+
+Commit b7dd0e350e0b (x86/xen: safely map and unmap grant frames when
+in atomic context) causes PVH guests to crash in
+arch_gnttab_map_shared() when they attempted to map the pages for the
+grant table.
+
+This use of a PV-specific function during the PVH grant table setup is
+non-obvious and not needed.  The standard vmap() function does the
+right thing.

+Subject: xen/events/fifo: ensure all bitops are properly aligned even on x86
+
+From: David Vrabel <david.vrabel@citrix.com>
+
+commit dcecb8fd93a65787130a74e61fdf29932c8d85eb upstream.
+
+When using the FIFO-based ABI on x86_64, if the last port is at the
+end of an event array page then sync_test_bit() on this port's event
+word will read beyond the end of the page and in certain circumstances
+this may fault.
+
+The fault requires the following page in the kernel's direct mapping
+to be not present, which would mean:
+
+a) the array page is the last page of RAM; or
+
+b) the following page is ballooned out /and/ it has been used for a
+   foreign mapping by a kernel driver (such as netback or blkback)
+   /and/ the grant has been unmapped.
+
+Use the infrastructure added for arm64 to ensure that all bitops
+operating on event words are unsigned long aligned.
