Add changes to support multimode invocation ioctl request. This
ioctl call facilitates multiple types of requests from user including
CRC check, performance counters, shared context bank usage, etc.
This series also carries patch to save and restore interrupted
context.

Ekansh Gupta (5):
  misc: fastrpc: Add fastrpc multimode invoke request support
  misc: fastrpc: Add CRC support for remote buffers
  misc: fastrpc: Capture kernel and DSP performance counters
  misc: fastrpc: Add support to save and restore interrupted
  misc: fastrpc: Add support to allocate shared context bank

I can't see where you are properly checking the reserved fields in your
new ioctl structures, am I just missing that logic somewhere?

thanks,
