It is not guaranteed that I2S RX is disabled when the kernel booting.
For example, if the kernel crashes while it is enabled, it will keep
enabled until the next time EC reboots. Reset I2S RX when probing to

It's never a good idea to send fixes and cleanups/refactors in the same

This series fixes various issues observed in latest kernel on RV32.
The first two patches fixes an resource tree introduced in 5.11-rc1
while the last two fixes the case where 2GB physical memory is used
on RV32.
There are may be better way to fix the issue pointed out in PATCH 3

Currently, linux kernel can not use last 4k bytes of addressable space because
IS_ERR_VALUE macro treats those as an error. This will be an issue for RV32
as any memblock allocator potentially allocate chunk of memory from the end
of DRAM (2GB) leading bad address error even though the address was
On the following call path, `sig->pkey_algo` is not assigned
in asymmetric_key_verify_signature(), which causes runtime
crash in public_key_verify_signature().
keyctl_pkey_verify
asymmetric_key_verify_signature
verify_signature
public_key_verify_signature
This patch simply
Currently, resource tree allocates memory blocks while iterating on the
list. It leads to following kernel warning because memblock allocation
also invokes memory block reservation API.
[0.00] [ cut here ]
[0.00] WARNING: CPU: 0 PID: 0 at
SMP_CACHE_BYTES/L1_CACHE_BYTES should be defined as 32 instead of
64 for RV32. Otherwise, there will be hole of 32 bytes with each memblock
allocation if it is requested to be aligned with SMP_CACHE_BYTES.

Hi,
In patch series[1], I put forward some fixes and optimizations for
vfio_iommu_type1. This extracts and improves the fix part of it.

vfio/iommu_type1: Fixes
We should populate dirty bitmap for newly added vfio_dma as it can be
accessed arbitrarily if vfio_iommu is not promoted to pinned_scope.
vfio_dma_populate_bitmap can handle this properly.
Fixes: d6a4c185660c ("vfio iommu: Implementation of ioctl for dirty pages
tracking")
Signed-off-by: Keqian
Defer checking whether vfio_dma is of fully-dirty in update_user_bitmap
is easy to lose dirty log. For example, after promoting pinned_scope of
vfio_iommu, vfio_dma is not considered as fully-dirty, then we may lose
dirty log that occurs before vfio_iommu is promoted.
The key point is that
