kernel: update kernel 4.4 to 4.4.69

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] 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.

-
-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.
