brcm2708: update linux 4.4 patches to latest version
As usual these patches were extracted and rebased from the raspberry pi repo:
https://github.com/raspberrypi/linux/tree/rpi-4.4.y
- led1 can't be controlled on rpi-3 for linux 4.4, remove it.
- Fix modules.mk typos.

+Subject: [PATCH] kbuild: add -fno-PIE
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 8ae94224c9d72fc4d9aaac93b2d7833cf46d7141 upstream.
+
+Debian started to build the gcc with -fPIE by default so the kernel
+build ends before it starts properly with:
+|kernel/bounds.c:1:0: error: code model kernel does not support PIC mode
+
+Also add to KBUILD_AFLAGS due to:
+
+|gcc -Wp,-MD,arch/x86/entry/vdso/vdso32/.note.o.d … -mfentry -DCC_USING_FENTRY … vdso/vdso32/note.S
+|arch/x86/entry/vdso/vdso32/note.S:1:0: sorry, unimplemented: -mfentry isn’t supported for 32-bit in combination with -fpic
+
+Tagging it stable so it is possible to compile recent stable kernels as
+well.

+Subject: [PATCH] kbuild: Steal gcc's pie from the very beginning
+
+commit c6a385539175ebc603da53aafb7753d39089f32e upstream.
+
+So Sebastian turned off the PIE for kernel builds but that was too late
+- Kbuild.include already uses KBUILD_CFLAGS and trying to disable gcc
+options with, say cc-disable-warning, fails:
+
+ gcc -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs
+ ...
+ -Wno-sign-compare -fno-asynchronous-unwind-tables -Wframe-address -c -x c /dev/null -o .31392.tmp
+ /dev/null:1:0: error: code model kernel does not support PIC mode
+
+because that returns an error and we can't disable the warning. For
+example in this case:
+
+KBUILD_CFLAGS += $(call cc-disable-warning,frame-address,)
+
+which leads to gcc issuing all those warnings again.
+
+So let's turn off PIE/PIC at the earliest possible moment, when we
+declare KBUILD_CFLAGS so that cc-disable-warning picks it up too.
+
+Also, we need the $(call cc-option ...) because -fno-PIE is supported
+since gcc v3.4 and our lowest supported gcc version is 3.2 right now.

+The RPi GPIO no longer support run-time "pull" settings - one should
+Device Tree and pinctrl instead - so remove the parameter to avoid

+Subject: [PATCH] Revert "HID: dragonrise: fix HID Descriptor for 0x0006 PID"
+
+[ Upstream commit 1bcaa05ebee115213e34f1806cc6a4f7a6175a88 ]
+This reverts commit 18339f59c3a6 ("HID: dragonrise: fix HID...") because it
+breaks certain dragonrise 0079:0006 gamepads. While it may fix a breakage
+caused by commit 79346d620e9d ("HID: input: force generic axis to be mapped
+to their user space axis"), it is probable that the manufacturer released
+different hardware with the same PID so this fix works for only a subset
+and breaks the other gamepads sharing the PID.
+
+What is needed is another more generic solution which fixes 79346d620e9d
+("HID: input: force generic axis ...") breakage for this controller: we
+need to add an exception for this driver to make it keep the old behaviour
+previous to the initial breakage (this is done in patch 2 of this series).

+Subject: [PATCH] pisound improvements: (#1778)
+
+* Added a writable sysfs object to enable scripts / user space software
+to blink MIDI activity LEDs for variable duration.
+* Improved hw_param constraints setting.
+* Added compatibility with S16_LE sample format.
+* Exposed some simple placeholder volume controls, so the card appears
+in volumealsa widget.

+Subject: [PATCH] configfs: Remove ppos increment in configfs_write_bin_file
+
+[ Back-port of f8608985f851c917b3884b692d8e326b0210d34e ]
+
+The simple_write_to_buffer() already increments the @ppos on success,
+see fs/libfs.c simple_write_to_buffer() comment:
+
+"
+On success, the number of bytes written is returned and the offset @ppos
+advanced by this number, or negative value is returned on error.
+"
+
+If the configfs_write_bin_file() is invoked with @count smaller than the
+total length of the written binary file, it will be invoked multiple times.
+Since configfs_write_bin_file() increments @ppos on success, after calling
+simple_write_to_buffer(), the @ppos is incremented twice.
+
+Subsequent invocation of configfs_write_bin_file() will result in the next
+piece of data being written to the offset twice as long as the length of
+the previous write, thus creating buffer with "holes" in it.
+
+The simple testcase using DTO follows:
+ $ mkdir /sys/kernel/config/device-tree/overlays/1
+ $ dd bs=1 if=foo.dtbo of=/sys/kernel/config/device-tree/overlays/1/dtbo
+Without this patch, the testcase will result in twice as big buffer in the
+kernel, which is then passed to the cfs_overlay_item_dtbo_write() .

+
+Bring bcm2709_defconfig up to the level of bcmrpi_defconfig with
+respect to USB support. This is prompted by the introduction of CM3,
+which makes gadget mode on 2709/2710 a useful option.
+
+Note that the DWC2 driver is not loaded by default and must be enabled
+using a DT overlay or custom .dtb.

+Subject: [PATCH] BCM270X_DT: Add reference to audio_pins to CM dtb
+
+The CM1 dtb contains an empty audio_pins node, but no reference to it.
+Adding the usual pinctrl reference from the audio node enables the
+audremap overlay (and others) to easily turn on audio.

+Subject: [PATCH] x86/ioapic: Restore IO-APIC irq_chip retrigger callback
+
+commit 020eb3daaba2857b32c4cf4c82f503d6a00a67de upstream.
+
+commit d32932d02e18 removed the irq_retrigger callback from the IO-APIC
+chip and did not add it to the new IO-APIC-IR irq chip.
+
+Unfortunately the software resend fallback is not enabled on X86, so edge
+interrupts which are received during the lazy disabled state of the
+interrupt line are not retriggered and therefor lost.
+
+Restore the callbacks.

+Subject: [PATCH] drm/vc4: Fix sending of page flip completion events in FKMS
+ mode.
+
+In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
+CRTC's atomic flush handler that moved the completion event from the
+proposed atomic state change to the CRTC's current state. That meant
+that when full screen pageflipping happened (glxgears -fullscreen in
+X, compton, por weston), the app would end up blocked firever waiting
+to draw its next frame.

+Subject: [PATCH] clk: bcm: Support rate change propagation on bcm2835 clocks
+
+Some peripheral clocks, like the VEC (Video EnCoder) clock need to be set
+to a precise rate (in our case 108MHz). With the current implementation,
+where peripheral clocks are not allowed to forward rate change requests
+to their parents, it is impossible to match this requirement unless the
+bootloader has configured things correctly, or a specific rate has been
+assigned through the DT (with the assigned-clk-rates property).
+
+Add a new field to struct bcm2835_clock_data to specify which parent
+clocks accept rate change propagation, and support set rate propagation
+in bcm2835_clock_determine_rate().

+Subject: [PATCH] clk: bcm2835: Don't rate change PLLs on behalf of DSI PLL
+ dividers (v2).
+
+Our core PLLs are intended to be configured once and left alone. With
+the SET_RATE_PARENT, asking to set the PLLD_DSI1 clock rate would
+change PLLD just to get closer to the requested DSI clock, thus
+changing PLLD_PER, the UART and ethernet PHY clock rates downstream of
+it, and breaking ethernet.
+
+We *do* want PLLH to change so that PLLH_AUX can be exactly the value
+we want, though. Thus, we need to have a per-divider policy of
+whether to pass rate changes up.

+Subject: [PATCH] drm/vc4: Fulfill user BO creation requests from the kernel BO
+ cache.
+
+The from_cache flag was actually "the BO is invisible to userspace",
+so we can repurpose to just zero out a cached BO and return it to
+userspace.
+
+Improves wall time for a loop of 5 glsl-algebraic-add-add-1 by
+-1.44989% +/- 0.862891% (n=28, 1 outlier removed from each that
+appeared to be other system noise)
+
+Note that there's an intel-gpu-tools test to check for the proper
+zeroing behavior here, which we continue to pass.

+
+If a CMA allocation failed, the partially constructed BO would be
+unreferenced through the normal path, and we might choose to put it in
+the BO cache. If we then reused it before it expired from the cache,
+the kernel would OOPS.

+Subject: [PATCH] Update vfpmodule.c
+
+Christopher Alexander Tobias Schulze - May 2, 2015, 11:57 a.m.
+This patch fixes a problem with VFP state save and restore related
+to exception handling (panic with message "BUG: unsupported FP
+instruction in kernel mode") present on VFP11 floating point units
+(as used with ARM1176JZF-S CPUs, e.g. on first generation Raspberry
+Pi boards). This patch was developed and discussed on
+
+ https://github.com/raspberrypi/linux/issues/859
+
+A precondition to see the crashes is that floating point exception
+traps are enabled. In this case, the VFP11 might determine that a FPU
+operation needs to trap at a point in time when it is not possible to
+signal this to the ARM11 core any more. The VFP11 will then set the
+FPEXC.EX bit and store the trapped opcode in FPINST. (In some cases,
+a second opcode might have been accepted by the VFP11 before the
+exception was detected and could be reported to the ARM11 - in this
+case, the VFP11 also sets FPEXC.FP2V and stores the second opcode in
+FPINST2.)
+
+If FPEXC.EX is set, the VFP11 will "bounce" the next FPU opcode issued
+by the ARM11 CPU, which will be seen by the ARM11 as an undefined opcode
+trap. The VFP support code examines the FPEXC.EX and FPEXC.FP2V bits
+to decide what actions to take, i.e., whether to emulate the opcodes
+found in FPINST and FPINST2, and whether to retry the bounced instruction.
+
+If a user space application has left the VFP11 in this "pending trap"
+state, the next FPU opcode issued to the VFP11 might actually be the
+VSTMIA operation vfp_save_state() uses to store the FPU registers
+to memory (in our test cases, when building the signal stack frame).
+In this case, the kernel crashes as described above.
+
+This patch fixes the problem by making sure that vfp_save_state() is
+always entered with FPEXC.EX cleared. (The current value of FPEXC has
+already been saved, so this does not corrupt the context. Clearing
+FPEXC.EX has no effects on FPINST or FPINST2. Also note that many
+callers already modify FPEXC by setting FPEXC.EN before invoking
+vfp_save_state().)
+
+This patch also addresses a second problem related to FPEXC.EX: After
+returning from signal handling, the kernel reloads the VFP context
+from the user mode stack. However, the current code explicitly clears
+both FPEXC.EX and FPEXC.FP2V during reload. As VFP11 requires these
+bits to be preserved, this patch disables clearing them for VFP
+implementations belonging to architecture 1. There should be no
+negative side effects: the user can set both bits by executing FPU
+opcodes anyway, and while user code may now place arbitrary values
+into FPINST and FPINST2 (e.g., non-VFP ARM opcodes) the VFP support
+code knows which instructions can be emulated, and rejects other
+opcodes with "unhandled bounce" messages, so there should be no
+security impact from allowing reloading FPEXC.EX and FPEXC.FP2V.
