misc: pvpanic: introduce device capability
...
According to pvpanic spec:
https://git.qemu.org/?p=qemu.git;a=blob_plain;f=docs/specs/pvpanic.txt
The guest should determine pvpanic capability by RDPT, so initialize
capability during device probing. There is no need to register panic
notifier callback function if no events supported.
Before sending event to host side, check capability firstly.
Suggested by Greg KH, use sysfs to expose capability to user space,
also add new sysfs attribute in document.

misc: pti: Remove driver for deprecated platform
...
Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.
There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. The commit

VMCI: Enforce queuepair max size for IOCTL_VMCI_QUEUEPAIR_ALLOC
...
When create the VMCI queue pair tracking data structures on the host
side, the IOCTL for creating the VMCI queue pair didn't validate
the queue pair size parameters. This change adds checks for this.
This avoids a memory allocation issue in qp_host_alloc_queue, as
reported by nslusarek@gmx.net . The check in qp_host_alloc_queue
has also been updated to enforce the maximum queue pair size
as defined by VMCI_MAX_GUEST_QP_MEMORY.
The fix has been verified using sample code supplied by
nslusarek@gmx.net .

VMCI: Use set_page_dirty_lock() when unregistering guest memory
...
When the VMCI host support releases guest memory in the case where
the VM was killed, the pinned guest pages aren't locked. Use
set_page_dirty_lock() instead of set_page_dirty().
Testing done: Killed VM while having an active VMCI based vSocket
connection and observed warning from ext4. With this fix, no
warning was observed. Ran various vSocket tests without issues.

habanalabs: prevent soft lockup during unmap
...
When using Deep learning framework such as tensorflow or pytorch, there
are tens of thousands of host memory mappings. When the user frees
all those mappings at the same time, the process of unmapping and
unpinning them can take a long time, which may cause a soft lockup
bug.
To prevent this, we need to free the core to do other things during
the unmapping process. For now, we chose to do it every 32K unmappings
(each unmap is a single 4K page).

offset to the DMA address before returning to the callee function. This
offset is needed when our device use this DMA address to perform
outbound transactions to the host.
However, if we want to map the DMA'able memory to the user via
dma_mmap_coherent(), we need to pass the original dma address, without
this offset. Otherwise, we will get erronouos mapping.

misc: pvpanic: Check devm_ioport_map() for NULL
...
Inconveniently devm_ioport_map() and devm_ioremap_resource()
return errors differently, i.e. former uses simply NULL pointer,
while the latter an error pointer.
Due to this, we have to check each of them separately.

habanalabs: adjust pci controller init to new firmware
...
When the firmware security is enabled, the pcie_aux_dbi_reg_addr
register in the PCI controller is blocked. Therefore, ignore
the result of writing to this register and assume it worked. Also
remove the prints on errors in the internal ELBI write function.
If the security is enabled, the firmware is responsible for setting
this register correctly so we won't have any problem.
If the security is disabled, the write will work (unless something
is totally broken at the PCI level and then the whole sequence
will fail).
In addition, remove a write to register pcie_aux_dbi_reg_addr+4,
which was never actually needed.
Moreover, PCIE_DBI registers are blocked to access from host when
firmware security is enabled. Use a different register to flush the
writes.
