[STABLE-4.4] proposed backports

[STABLE-4.4] proposed backports

[Arnd Bergmann]

I looked at the kernelci.org output for 4.4.y and found a couple of
patches that need to be applied here:

0eca6fdb3193 ("ARC: Assume multiplier is always present")
1dec78585328 ("ARC: fix build warning in elf.h")
173a3efd3edb ("bug.h: work around GCC PR82365 in BUG()")
8535f2ba0a9b ("MIPS: math-emu: do not use bools for arithmetic")
67fc5dc8a541 ("MIPS: VDSO: Include $(ccflags-vdso) in o32,n32 .lds builds")
993dc737c099 ("mfd: omap-usb-tll: Fix register offsets")
386744425e35 ("swiotlb: Make linux/swiotlb.h standalone includible")

Further, the backport of commit 867bfa4a5fce ("fs/binfmt_flat.c: make
load_flat_shared_library() work") relies on commit bdd1d2d3d251 ("fs:
fix kernel_read prototype"). Either that gets backported as well, or
the new patch dropped or modified:

fs/binfmt_flat.c:832:35: warning: passing argument 2 of 'kernel_read'
makes integer from pointer without a cast [-Wint-conversion]
include/uapi/linux/binfmts.h:18:25: warning: passing argument 3 of
'kernel_read' makes pointer from integer without a cast
[-Wint-conversion]
fs/binfmt_flat.c:832:58: warning: passing argument 4 of 'kernel_read'
makes integer from pointer without a cast [-Wint-conversion]

Here is a similar list for 4.9, from
https://kernelci.org/build/stable-rc/branch/linux-4.9.y/kernel/v4.9.184-66-g79155cd391a8/

8535f2ba0a9b ("MIPS: math-emu: do not use bools for arithmetic")
02eec6c9fc0c ("MIPS: netlogic: xlr: Remove erroneous check in nlm_fmn_send()")
173a3efd3edb ("bug.h: work around GCC PR82365 in BUG()")
993dc737c099 ("mfd: omap-usb-tll: Fix register offsets")
5464d03d9260 ("ARC: fix allnoconfig build warning")

On 4.14, I can only see one missing patch in
https://kernelci.org/build/stable-rc/branch/linux-4.14.y/kernel/v4.14.132-2-g69aa9e7d0127/

02eec6c9fc0c ("MIPS: netlogic: xlr: Remove erroneous check in nlm_fmn_send()")

though there are still a few more build issues that need further investigation:

cc1: error: '-march=r3000' requires '-mfp32'

fs/proc/task_mmu.c:761:7: warning: 'last_vma' may be used
uninitialized in this function [-Wmaybe-uninitialized]

warning: (SIBYTE_SWARM && SIBYTE_SENTOSA && SIBYTE_BIGSUR &&
SWIOTLB_XEN && AMD_IOMMU) selects SWIOTLB which has unmet direct
dependencies (CAVIUM_OCTEON_SOC || MACH_LOONGSON64 && CPU_LOONGSON3 ||
NLM_XLP_BOARD || NLM_XLR_BOARD)

This one was wrong: the patch is already there, but we still get the
same build warning that it was supposed to fix, same on 4.9 and 4.14

I took all of these except 67fc5dc8a541.

I've fixed it up.

Thank you!
