to the ftrace function callback infrastructure. It's introducing a
way to allow different functions to call directly different trampolines
instead of all calling the same "mcount" one.
The only user of this for now is the function graph tracer, which always
had a different trampoline, but the function tracer trampoline was called
and did basically nothing, and then the function graph tracer trampoline
was called. The difference now, is that the function graph tracer
trampoline can be called directly if a function is only being traced by
the function graph trampoline. If function tracing is also happening on
the same function, the old way is still done.
The accounting for this takes up more memory when function graph tracing
is activated, as it needs to keep track of which functions it uses.
I have a new way that wont take as much memory, but it's not ready yet
for this merge window, and will have to wait for the next one.
Another big change was the removal of the ftrace_start/stop() calls that
were used by the suspend/resume code that stopped function tracing when
entering into suspend and resume paths. The stop of ftrace was done
because there was some function that would crash the system if one called
smp_processor_id()! The stop/start was a big hammer to solve the issue
at the time, which was when ftrace was first introduced into Linux.
Now ftrace has better infrastructure to debug such issues, and I found
the problem function and labeled it with "notrace" and function tracing
can now safely be activated all the way down into the guts of suspend
and resume.
Other changes include clean ups of uprobe code.
Clean up of the trace_seq() code.
And other various small fixes and clean ups to ftrace and tracing.

If scsi_remove_host() is called while an rport is in the blocked state
then scsi_remove_host() will only finish if the rport is unblocked
from inside a timer function. Make sure that an rport only enters the
blocked state if a timer will be started that will unblock it. This
avoids that unloading the ib_srp kernel module after having
disconnected the initiator from the target system results in a
deadlock if both the fast_io_fail_tmo and dev_loss_tmo parameters have
been set to "off".

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

- add host_lock option whose default value is 0 which removes the
host_lock around all queued commands
- accept delay=-1 (_hi_) or -2 which use a tasklet to invoke
the scsi_done callback into the mid-layer. The default
is still delay=1 which uses a timer to delay 1 jiffy
- wire .change_queue_depth and .change_queue_type
functions to better simulate queueing in a modern LLD
- add SCSI_DEBUG_OPT_Q_NOISE (0x200) mask to only produce
debug output associated with queue full, plus from
.change_queue_depth and .change_queue_type functions
- add SCSI_DEBUG_OPT_ALL_TSF (0x400) mask which reports
all queued_arr fulls at TASK_SET_FULL, otherwise
SCSI_MLQUEUE_HOST_BUSY is returned
- add SCSI_DEBUG_OPT_RARE_TSF (0x800) mask which works
together with the every_nth option (> 0) to count
occurrences of num_in_q==queue_depth. When every_nth
is reached the victim (a command) yields TASK SET FULL
- clean up many debug messages.
- add ndelay=<nanosecs> option that uses high resolution
timers; active if > 0 and then overrides delay= option
- expand Unit Attention handling: POR, BUS_RESET and
MODE PARAMETERS CHANGED
- support .eh_target_reset_handler and drop .bios_param
- add OPT_N_WCE mask so caching page yields WCE=0
- add OPT_RESET_NOISE mask to log aborts and resets
- add OPT_NO_CDB_NOISE mask to not log each cdb
- MODE SELECT support for changing caching page's WCE
- name common ioctls in log
- when fake_rw=1, do not vmalloc fake store; make
UNMAP and WRITE SAME obey fake_rw
- more logging and code improvements including better
sense buffer handling
With fio and four (pseudo) devices I have observed 1.2 M IOPS
on my equipment. Rob Elliott who has done much testing and made
numerous suggestions, has better IOPS results than mine.

During hibernation, the HBA firmware may lose power and forget the device
id info. This causes the HBA to reject IO upon resume. The fix is
to call the libsas power management routines to make the domain device
forgetful.

In _scsih_probe, delay the call to scsi_add_host until the host has been
fully set up.
Otherwise, the default .can_queue value of 1 causes scsi-mq to set the block
layer request queue size to its minimum size, resulting in awful performance.
In _scsih_probe error handling, call mpt3sas_base_detach rather than
scsi_remove_host to properly clean up in reverse order.
In _scsih_remove, call scsi_remove_host earlier to clean up in reverse order.
