26abfeed43 EISA: Initialize device before its resources
Move eisa_init_device() before eisa_request_resources() so the device
name is set before we set up its resources.  That way we can print
better messages.

Previously edev->res[i].name was set to NULL in eisa_request_resources(),
then filled in by eisa_init_device().  Now it is filled in by
eisa_init_device() first, and we don't want to clear it out later in
eisa_request_resources().

545d7b78e0 PCI: Use PCI_EXP_SLTCAP_PSN mask when extracting slot number
Use PCI_EXP_SLTCAP_PSN mask to make it easier to find where the
Physical Slot Number is used.

The Physical Slot Number is bits 31:19 of the Slot Capabilities Register,
and slot_cap is a u32, so the mask is technically unnecessary, but it's
helpful for human readers.

9a97cd43f4 MIPS/PCI: Implement pcibios_get_phb_of_node
The of_node field of the device assigned to a
PCI bus is used during scanning of the PCI bus.
However on MIPS, the of_node field is assigned
only after the bus has been scanned.

Implement the architecture specific version of
'pcibios_get_phb_of_node'. Which ensures that the
PCI driver core will initialize the of_node field
before starting the scan.

Also remove the local assignment of bus->dev.of_node,
it is not needed after the patch.

10629d711e PCI: Remove __weak annotation from pcibios_get_phb_of_node decl
The __weak annotation on the pcibios_get_phb_of_node() declaration
causes *every* definition to be marked "weak."  The linker then
selects one based on link order, which may be the wrong one.

Gabor found that on MIPS, the linker selected the generic implementation
from drivers/pci even though arch/mips supplied a definition without the
__weak annotation:

$ mipsel-openwrt-linux-readelf -s arch/mips/pci/built-in.o \
    drivers/pci/built-in.o vmlinux.o | grep pcibios_get_phb_of_node
      86: 0000046c    12 FUNC    WEAK   DEFAULT    2 pcibios_get_phb_of_node
    1430: 00012e2c   104 FUNC    WEAK   DEFAULT    2 pcibios_get_phb_of_node
   31898: 0017e4ec   104 FUNC    WEAK   DEFAULT    2 pcibios_get_phb_of_node

This removes the __weak annotation from the pcibios_get_phb_of_node()
declaration so arch-specific non-weak implementations work reliably.

Currently the aer_inject driver returns -ENOTTY when the target PCIe
device root port is not found or if the device or root port doesn't

In the case where the root port isn't found, the driver should return

85467136cd PCI: Add PCI_BUS_NUM() and PCI_DEVID() interfaces
PCI defines PCI_DEVFN(), PCI_SLOT(), and PCI_FUNC() interfaces; however,
it doesn't have interfaces to return PCI bus and PCI device id. Drivers
(AMD IOMMU, and AER) implement module specific definitions for PCI_BUS()
and AMD_IOMMU driver also has a module specific interface to calculate PCI
device id from bus number and devfn.

Add PCI_BUS_NUM and PCI_DEVID interfaces to return PCI bus number and PCI
device id respectively to avoid the need for duplicate definitions in other
modules. AER driver code and AMD IOMMU driver define PCI_BUS. AMD IOMMU
driver defines an interface to calculate device id from bus number, and
devfn pair.

PCI_DEVFN(), PCI_SLOT(), and PCI_FUNC() interfaces are exported to
user-space via uapi/linux/pci.h. However, in the interest to keep the new
interfaces as kernel only and not export them to user-space unnecessarily,
added them to linux/pci.h instead.

8343bce195 Atmel MXT touchscreen: increase reset timeouts
There is a more complete atmel patch-series out by Nick Dyer that fixes
this and other things, but in the meantime this is the minimal thing to
get the touchscreen going on (at least my) Pixel Chromebook.

Not that I want my dirty fingers near that beautiful screen, but it
seems that a non-initialized touchscreen will also end up being a
constant wakeup source, so you have to disable it to go to sleep.  And
it's easier to just fix the initialization sequence.

db04dc679b proc: Use nd_jump_link in proc_ns_follow_link
Update proc_ns_follow_link to use nd_jump_link instead of just
manually updating nd.path.dentry.

This fixes the BUG_ON(nd->inode != parent->d_inode) reported by Dave
Jones and reproduced trivially with mkdir /proc/self/ns/uts/a.

Sigh it looks like the VFS change to require use of nd_jump_link
happend while proc_ns_follow_link was baking and since the common case
of proc_ns_follow_link continued to work without problems the need for
making this change was overlooked.

22dfab7fd7 Input: atmel_mxt_ts - Support for touchpad variant
This same driver can be used by atmel based touchscreens and touchpads
(buttonpads). Platform data may specify a device is a touchpad
using the is_tp flag.

This will cause the driver to perform some touchpad specific
initializations, such as:
  * register input device name "Atmel maXTouch Touchpad" instead of
  Touchscreen.
  * register BTN_LEFT & BTN_TOOL_* event types.
  * register axis resolution (as a fixed constant, for now)
  * register BUTTONPAD property
  * process GPIO buttons using reportid T19

Input event GPIO mapping is done by the platform data key_map array.

key_map[x] should contain the KEY or BTN code to send when processing
GPIOx from T19. To specify a GPIO as not an input source, populate
with KEY_RESERVED, or 0.

d8fc16a825 ksm: fix m68k build: only NUMA needs pfn_to_nid
A CONFIG_DISCONTIGMEM=y m68k config gave

  mm/ksm.c: In function `get_kpfn_nid':
  mm/ksm.c:492: error: implicit declaration of function `pfn_to_nid'

linux/mmzone.h declares it for CONFIG_SPARSEMEM and CONFIG_FLATMEM, but
expects the arch's asm/mmzone.h to declare it for CONFIG_DISCONTIGMEM
(see arch/mips/include/asm/mmzone.h for example).

Or perhaps it is only expected when CONFIG_NUMA=y: too much of a maze,
and m68k got away without it so far, so fix the build in mm/ksm.c.

a40e7cf8f0 dmi_scan: fix missing check for _DMI_ signature in smbios_present()
Commit 9f9c9cbb60 ("drivers/firmware/dmi_scan.c: fetch dmi version
from SMBIOS if it exists") hoisted the check for "_DMI_" into
dmi_scan_machine(), which means that we don't bother to check for
"_DMI_" at offset 16 in an SMBIOS entry.  smbios_present() may also call
dmi_present() for an address where we found "_SM_", if it failed further
validation.

Check for "_DMI_" in smbios_present() before calling dmi_present().

dc893e19b5 Revert parts of "hlist: drop the node parameter from iterators"
Commit b67bfe0d42 ("hlist: drop the node parameter from iterators")
did a lot of nice changes but also contains two small hunks that seem to
have slipped in accidentally and have no apparent connection to the
intent of the patch.

This reverts the two extraneous changes.

2e1c9b2867 idr: remove WARN_ON_ONCE() on negative IDs
idr_find(), idr_remove() and idr_replace() used to silently ignore the
sign bit and perform lookup with the rest of the bits.  The weird behavior
has been changed such that negative IDs are treated as invalid.  As the
behavior change was subtle, WARN_ON_ONCE() was added in the hope of
determining who's calling idr functions with negative IDs so that they can
be examined for problems.

Up until now, all two reported cases are ID number coming directly from
userland and getting fed into idr_find() and the warnings seem to cause
more problems than being helpful.  Drop the WARN_ON_ONCE()s.
