iommu/exynos: Don't unconditionally steal bus ops
[ Upstream commit
dc98b8480d8a68c2ce9aa28b9f0d714fd258bc0b ]
Removing the early device registration hook overlooked the fact that
it only ran conditionally on a compatible device being present in the
DT. With exynos_iommu_init() now running as an unconditional initcall,
problems arise on non-Exynos systems when other IOMMU drivers find
themselves unable to install their ops on the platform bus, or at worst
the Exynos ops get called with someone else's domain and all hell breaks
loose.
The global ops/cache setup could probably all now be triggered from the
first IOMMU probe, as with dma_dev assigment, but for the time being the
simplest fix is to resurrect the logic from commit
a7b67cd5d9af
("iommu/exynos: Play nice in multi-platform builds") to explicitly check
the DT for the presence of an Exynos IOMMU before trying anything.

fs: proc: Add PROC_CMDLINE_APPEND_ANDROID_FORCE_NORMAL_BOOT
For Android 9 launch A/B devices migrating to Android 10 style
system-as-root, `androidboot.force_normal_boot=1` must be passed in
cmdline when booting into normal or charger mode. However, it is not
always possible for one to modify the bootloader to adhere to these
changes. As a workaround, one can use the presence of the
`skip_initramfs` flag in cmdline to to decide whether to append the new
flag to cmdline on the kernel side.

Since we need these optimizations for performance reasons, the only way to resolve this is to solve the issue. Samsung already did something similar to cal-if before.
We only needed to make fvmap_header/header volatile and has been tested to work.

mm: prevent a warning when casting void* -> enum
I recently build the RISC-V port with LLVM trunk, which has introduced a

This patch simply casts to a long in the middle to stop the warning. I'd
