In ecryptfs_init_messaging(), if the allocation for 'ecryptfs_msg_ctx_arr'

Applied to 5.4/scsi-queue. Thanks!

This looks weird. The only place calling yor new method only does so
after checking that it is not set and actually warns if it set?

According to PLL1443XA and PLL1416X spec,
"When BYPASS is 0 and RESETB is changed from 0 to 1, FOUT starts to
output unstable clock until lock time passes. PLL1416X/PLL1443XA may
generate a glitch at FOUT."
So set BYPASS when RESETB is changed from 0 to 1 to avoid glitch.

Normally, the HV emulates some instructions like MSGSNDP, MSGCLRP

Secure guests need to share the DTL buffers with the hypervisor. To that
end, use a kmem_cache constructor which converts the underlying buddy

Secure guest memory is inacessible to devices so regular DMA isn't
possible.
In that case set devices' dma_map_ops to NULL so that the generic
DMA code path will use SWIOTLB to bounce buffers for DMA.

The ultracalls (ucalls for short) allow the Secure Virtual Machines

accessing a register or memory region that can only be accessed when
running in ultravisor-privileged mode.
