This patch adds a new network driver implementing MHI transport for
network packets. Packets can be in any format, though QMAP (rmnet)
is the usual protocol (flow control + PDN mux).
It support two MHI devices, IP_HW0 which is, the path to the IPA
(IP accelerator) on qcom modem, And IP_SW0 which i

Device managed memory exposes itself to the kernel direct map which
allows stray pointers to access these device memories.
Stray pointers to normal memory may result in a crash or other
undesirable behavior which, while unfortunate, are usually recoverable
with a reboot. Stray a

Device managed pages may have additional protections. These protections
need to be removed prior to valid use by kernel users.
Check for special treatment of device managed pages in kmap and take
action if needed. We use kmap as an interface for generic kernel code
because unde

To correctly support the semantics of kmap() with Kernel protection keys
(PKS), kmap() may be required to set the protections on multiple
processors (globally). Enabling PKS globally can be very expensive
depending on the requested operation. Furthermore, enabling a domain
