Pinned pages are not properly accounted particularly when
mapping error occurs on IOTLB update. Clean up dangling
pinned pages for the error path. As the inflight pinned
pages, specifically for memory region that strides across
multiple chunks, would need more than one free page for
book keeping
vhost_vdpa_map() should remove the iotlb entry just added
if the corresponding mapping fails to set up properly.

Commit 4c8cf31885f6 ("vhost: introduce vDPA-based backend")
has following issues in the failure path of IOTLB update:
1) vhost_vdpa_map() does not clean up dangling iotlb entry
upon mapping failure
2) vhost_vdpa_process_iotlb_update() has leakage of pinned
pages in case of vhost_vdpa_map()

An SGX runtime must be aware of the exceptions, which happen inside an
enclave. Introduce a vDSO call that wraps EENTER/ERESUME cycle and returns
the CPU exception back to the caller exactly when it happens.
Kernel fixups the exception information to RDI, RSI and RDX.
Add an ioctl, which performs ENCLS[EADD] that adds new visible page to an
enclave, and optionally ENCLS[EEXTEND] operations that hash the page to the
enclave measurement. By visible we mean a page that can be mapped to the
address range of an enclave.

This patch adds support for collecting minidump in the event of remoteproc
crash. Parse the minidump table based on remoteproc's unique minidump-id,
read all memory regions from the remoteproc's minidump table entry and
expose the memory to userspace. The remoteproc platform driver can choose
to
Add minidump id for modem in sm8150 chipset so that the regions to be
included in the coredump generated upon a crash is based on the minidump
tables in SMEM instead of those in the ELF header.

This change adds a new kind of core dump mechanism which instead of dumping
entire program segments of the firmware, dumps sections of the remoteproc
memory which are sufficient to allow debugging the firmware. This function
thus uses section headers instead of program headers during creation of
