This does not permit mapping larger regions (such as a PCI memory
BAR) and it does not permit mapping addresses beyond the top of RAM
(such as a 64-bit BAR located above the top of RAM).
Instead of using a single OBJT_DEVICE object and passing the physaddr via
the offset as a hack, create a new sglist and OBJT_SG object for each
mmap request. The requested memory attribute is applied to the object
thus affecting all pages mapped by the request.

from the behaviour in Linux, whose implementation does not add the extra
tick, so subtract the extra tick in the OFED compat layer implementation.
This addresses some incorrect handling of IB MAD timeouts, since some IB
code depends on msecs_to_jiffies(0) returning 0.

the existing "linux_timer_jiffies_until()" function. Negative timeouts
can result in undefined behaviour.
- declare all completion functions like external symbols and move the

- add a proper prefix to all LinuxAPI kernel functions to avoid
namespace collision with other parts of the FreeBSD kernel.

- The linux compat API layer casts the ticks to unsigned long which

- Guard against already expired ticks values, by checking if the
passed expiry tick is already elapsed.

Introduce fget_fcntl which performs appropriate checks when needed.
This removes a branch from fget_unlocked.
Introduce fget_mmap dealing with cap_rights_to_vmprot conversion.
This removes a branch from _fget.
Modify fget_unlocked to pass sequence counter to interested callers so
that they can perform their own checks and make sure the result was
otained from stable & current state.
