Pull RISC-V fixes from Palmer Dabbelt:
"This contains a handful of RISC-V related fixes that I've collected
and would like to target for 5.6-rc4:
- A fix to set up the PMPs on boot, which allows the kernel to access
memory on systems that don't set up permissive PMPs before getting
to Linux. This only effects machine-mode kernels, which currently
means only NOMMU kernels.
- A fix to avoid enabling supervisor-mode interrupts when running in
machine-mode, also only for NOMMU kernels.
- A pair of fixes to our KASAN support to avoid corrupting memory.
- A gitignore fix.
This boots on QEMU's virt board for me"
* tag 'riscv-for-linux-5.6-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
riscv: adjust the indent
riscv: allocate a complete page size for each page table
riscv: Fix gitignore
RISC-V: Don't enable all interrupts in trap_init()
riscv: set pmp configuration if kernel is running in M-mode

Some DSI and VBT pending patches from Hans will apply
cleanly and with less ugly conflicts if they are rebuilt
on top of other patches that recently landed on drm-next.

If the flag SB_FLAG_RECALCULATE is present in the superblock, but it was
not specified on the command line (i.e. ic->recalculate_flag is false),
dm-integrity would return invalid table line - the reported number of
arguments would not match the real number.

If we need to perform synchronous I/O in dm_integrity_map_continue(),
we must make sure that we are not in the map function - in order to
avoid the deadlock due to bio queuing in generic_make_request. To
avoid the deadlock, we offload the request to metadata_wq.
However, metadata_wq also processes metadata updates for write requests.
If there are too many requests that get offloaded to metadata_wq at the
beginning of dm_integrity_map_continue, the workqueue metadata_wq
becomes clogged and the system is incapable of processing any metadata
updates.
This causes a deadlock because all the requests that need to do metadata
updates wait for metadata_wq to proceed and metadata_wq waits inside
wait_and_add_new_range until some existing request releases its range
lock (which doesn't happen because the range lock is released after
metadata update).
In order to fix the deadlock, we create a new workqueue offload_wq and
offload requests to it - so that processing of offload_wq is independent
from processing of metadata_wq.

If we resume a device in bitmap mode and the on-disk format is in journal
mode, we must recalculate anything above ic->sb->recalc_sector. Otherwise,
there would be non-recalculated blocks which would cause I/O errors.

Using a heavy-weight TLB flush once is not sufficient. Concurrent
memory accesses in the same TLB cache line can re-populate TLB entries
from stale texture cache (TC) entries while the heavy-weight TLB
flush is in progress. To fix this race condition, perform another TLB
flush after the heavy-weight one, when TC is known to be clean.
Move the workaround into the low-level TLB flushing functions. This way
they apply to amdgpu as well, and KIQ-based TLB flush only needs to
synchronize once.
