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.

-
-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.

-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.

-
-When enterring interrupt context via handle_int or except_vec_vi, switch

-
-The current stack pointer is masked with the thread size and compared to

-
-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.

+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.
