4d53dc0c02 drm/edid: Add CEA modes before inferred modes
Currently we're adding CEA modes after the inferred modes, which means
we might get multiple modes that are very close to each other, but
slightly different, which seems a bit silly. That's because duplicate
mode check that occurs when adding inferred modes would not consider
CEA modes as potential duplicates. Reverse the order so that CEA
modes get added before inferred modes, and are thus considered potential
duplicates.

Or as ajax put it on irc:
"< ajax> the point of the "pick a timing formula" heuristic was to
generate something the sink could _likely_ sink.  if it tells us
timings it can sink explicitly then second-guessing seems dumb."

ec04847c0c RDMA/core: Fix for parsing netlink string attribute
The string iwpm_ulib_name is recorded in a nlmsg as a netlink attribute.
Without this fix parsing of the nlmsg by the userspace port mapper service fails
because of unknown attribute length, causing the port mapper service not to
register the client, which has sent the nlmsg.

620b155034 MIPS: fix FP mode selection in lieu of .MIPS.abiflags data
Commit 46490b5725 ("MIPS: kernel: elf: Improve the overall ABI and FPU
mode checks") reworked the ELF FP ABI mode selection logic, but when
CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries
which have no PT_MIPS_ABIFLAGS program header & associated
.MIPS.abiflags section.

A default mode is selected based upon whether the ELF contains MIPS32 or
MIPS64 code, but that selection is made in arch_elf_pt_proc.
arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is
found. If one is not found then arch_elf_pt_proc is never called, and no
default overall_fp_mode value is selected. When arch_check_elf is
called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both
prog_req & interp_req being set to none_req. none_req matches none of
the conditions for mode selection at the end of arch_check_elf, so
overall_fp_mode is left untouched. Finally once mips_set_personality_fp
is called the BUG() in the default case is then hit & the kernel likely
panics.

Fix this by moving the selection of a default overall mode to the start
of arch_check_elf, which runs once per ELF executed regardless of
whether it has a PT_MIPS_ABIFLAGS program header.

699dcffc52 [media] rtl2832: add support for GoTView MasterHD 3 USB tuner
GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner.

It's based on the following components:
- USB bridge: RTL2832P (contains also DVB-T demodulator)
- Demodulator: Si2168-A30
- Tuner: Si2148-A20

The demodulator and the tuner will need firmwares. The Si2148 uses Si2158
firmware. Antti has the firmwares available for download:
http://palosaari.fi/linux/v4l-dvb/firmware/

Do note that for DVB-T either of the demodulators can be used. DVB-C and
DVB-T2 are only supported by the Si2168 demodulator. The driver will
register 2 frontends for the same adapter. Frontend 0 will be the RTL2832
demodulator and frontend 1 will be the Si2168 demodulator. The same
tuner is used for both.

As a consequence of the above, it's recommended to use application that
does implement proper DVBv5 support.

For some reason, the old I2C write method sporadically fails. Thus the
need for an option to only use the new I2C write method supported by the
RTL2832.

ee3c3e4688 [media] si2157: support selection of IF interface
The chips supported by the si2157 driver have two IF outputs (either
pins 12+13 or pins 9+11). Instead of hardcoding the output to be used
add an option to choose which output shall be used.

As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to
keep bisectability.

4801ba338a arm64: perf: fix memory leak when probing PMU PPIs
Commit d795ef9aa8 ("arm64: perf: don't warn about missing
interrupt-affinity property for PPIs") added a check for PPIs so that
we avoid parsing the interrupt-affinity property for these naturally
affine interrupts.

Unfortunately, this check can trigger an early (successful) return and
we will leak the irqs array. This patch fixes the issue by reordering
the code so that the check is performed before any independent
allocation.

7f7a4d306f phy: fix Kconfig dependencies
DM816x PHY uses usb_phy_* methods and because
of that, it must select USB_PHY, however, because
the drivers in question (DM816x, TWL4030 and
OMAP_USB2) sit outside of drivers/usb/ directory,
meaning they can be built even if USB_SUPPORT=n.

This patches fixes the dependencies by adding
USB_SUPPORT as a dependency and making all drivers
select USB_PHY (which cannot be selected through
menuconfig).

Note that this fixes some linking breakages when
building with randconfig.

3ebee5a2e1 arm64: dts: kill skeleton.dtsi
While skeleton.dtsi was initially conceived as a simple way to bootstrap
writing a dts, it has proven to be problematic:

* The #address-cells and #size-cells values used in skeleton.dtsi may
  not match what a user wants (e.g. when they need to describe a range
  larger than 4GB).

* For dts files where memory nodes have unit-addresses, it adds a
  redundant /memory node, for which the reg entry may not be
  appropriately sized (e.g. where #size-cells has been overridden).

* For dts files which assume that a bootloader will fill in the memory
  node(s), no node is present in the dts (and hence there is no attached
  comment), making it hard to distinguish these cases from bad dts
  files, and masking any warnings dtc may produce w.r.t. missing nodes.

* The default empty /chosen and /aliases are somewhat useless, and it
  would be preferable for dts to fill these in (e.g. for
  /aliases/serial0 and /chosen/stdout-path).

This patch removes skeleton.dtsi from arm64. There are currently no
users, so we can remove it before any appear.

3bb1555c0d ARM64: juno: add sp810 support and fix sp804 clock frequency
The clock generator in IOFPGA generates the two source clocks: 32kHz and
1MHz for the SP810 System Controller.

The SP810 System Controller selects 32kHz or 1MHz as the sources for
TIM_CLK[3:0], the SP804 timer clocks. The powerup default is 32kHz but
the maximum of "refclk" and "timclk" is chosen by the SP810 driver.

This patch adds support for SP810 system controller and also fixes the
SP804 timer clock frequency.

However the SP804 driver needs to be enabled on ARM64 to test this,
which requires SP804 driver to be moved out of arch/arm.

8df2914598 Merge branch 'netdev_page_frags'
Alexander Duyck says:

====================
Refactor netdev page frags and move them into mm/

This patch series addresses several things.

First I found an issue in the performance of the pfmemalloc check from
build_skb.  To work around it I have provided a cached copy of pfmemalloc
to be used in __netdev_alloc_skb and __napi_alloc_skb.

Second I moved the page fragment allocation logic into the mm tree and
added functionality for freeing page fragments.  I had to fix igb before I
could do this as it was using a reference to NETDEV_FRAG_PAGE_MAX_SIZE
incorrectly.

Finally I went through and replaced all of the duplicate code that was
calling put_page and replaced it with calls to skb_free_frag.

With these changes in place a simple receive and drop test increased from a
packet rate of 8.9Mpps to 9.8Mpps.  The gains breakdown as follows:

8.9Mpps	Before			9.8Mpps	After
------------------------	------------------------
7.8%	put_compound_page	9.1%	__free_page_frag
3.9%	skb_free_head
1.1%	put_page

4.9%	build_skb		3.8%	__napi_alloc_skb
2.5%	__alloc_rx_skb
1.9%	__napi_alloc_skb

181edb2bfa net: Add skb_free_frag to replace use of put_page in freeing skb->head
This change adds a function called skb_free_frag which is meant to
compliment the function netdev_alloc_frag.  The general idea is to enable a
more lightweight version of page freeing since we don't actually need all
the overhead of a put_page, and we don't quite fit the model of __free_pages.
