kernel: update kernel 4.4 to 4.4.69

Browse source 
Bump the 17.01 tree kernel to 4.4.69. Trunk 4.4 and 17.01 4.4 have diverged, talked this
through with jow, he was okay with a clean diff against 17.01 and not a backported trunk
patch.

The following patches were applied upstream:

* 062-[1-6]-MIPS-* series
* 042-0004-mtd-bcm47xxpart-fix-parsing-first-block

Reintroduced lantiq/patches-4.4/0050-MIPS-Lantiq-Fix-cascaded-IRQ-setup, as
it was incorrectly included upstream thus dropped from LEDE, but subsequently
reverted upstream. Thanks to Kevin Darbyshire-Bryant for pointing me to it.

  Compile-tested on: ar71xx, ramips/mt7621, x86/64.

  Run-tested on: ar71xx, ramips/mt7621, x86/64.

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] mtd: bcm47xxpart: fix parsing first block after aligned TRX
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
After parsing TRX we should skip to the first block placed behind it.
Our code was working only with TRX with length not aligned to the
blocksize. In other cases (length aligned) it was missing the block
places right after TRX.
This fixes calculation and simplifies the comment.

Subject: [PATCH] MIPS: Only change $28 to thread_info if coming from user
mode
The SAVE_SOME macro is used to save the execution context on all
exceptions.
If an exception occurs while executing user code, the stack is switched
to the kernel's stack for the current task, and register $28 is switched
to point to the current_thread_info, which is at the bottom of the stack
region.
If the exception occurs while executing kernel code, the stack is left,
and this change ensures that register $28 is not updated. This is the
correct behaviour when the kernel can be executing on the separate irq
stack, because the thread_info will not be at the base of it.
With this change, register $28 is only switched to it's kernel
conventional usage of the currrent thread info pointer at the point at
which execution enters kernel space. Doing it on every exception was
redundant, but OK without an IRQ stack, but will be erroneous once that
is introduced.

Subject: [PATCH] MIPS: Switch to the irq_stack in interrupts
When enterring interrupt context via handle_int or except_vec_vi, switch
to the irq_stack of the current CPU if it is not already in use.
The current stack pointer is masked with the thread size and compared to
the base or the irq stack. If it does not match then the stack pointer
is set to the top of that stack, otherwise this is a nested irq being
handled on the irq stack so the stack pointer should be left as it was.
The in-use stack pointer is placed in the callee saved register s1. It
will be saved to the stack when plat_irq_dispatch is invoked and can be
restored once control returns here.

From de856416e7143e32afc4849625616554aa060f7a Mon Sep 17 00:00:00 2001

Subject: [PATCH] MIPS: IRQ Stack: Fix erroneous jal to plat_irq_dispatch
Commit dda45f701c9d ("MIPS: Switch to the irq_stack in interrupts")
changed both the normal and vectored interrupt handlers. Unfortunately
the vectored version, "except_vec_vi_handler", was incorrectly modified
to unconditionally jal to plat_irq_dispatch, rather than doing a jalr to
the vectored handler that has been set up. This is ok for many platforms
which set the vectored handler to plat_irq_dispatch anyway, but will
cause problems with platforms that use other handlers.
Fixes: dda45f701c9d ("MIPS: Switch to the irq_stack in interrupts")

From: Felix Fietkau <nbd@nbd.name>
Date: Thu, 19 Jan 2017 12:14:44 +0100
Subject: [PATCH] MIPS: Lantiq: Fix cascaded IRQ setup
With the IRQ stack changes integrated, the XRX200 devices started
emitting a constant stream of kernel messages like this:
[ 565.415310] Spurious IRQ: CAUSE=0x1100c300
This appears to be caused by IP0 firing for some reason without being
handled. Fix this by setting up IP2-6 as a proper chained IRQ handler and
calling do_IRQ for all MIPS CPU interrupts.
