When we first submitted a userspace subnet management agent, it was

A lot of ipath layer code was only called in one place. Now that the

inline the simple stuff that the layer code was doing.

Ordering of writethrough store buffers needs to be forced, and we need

there is no generic way to specify that at this time (similar to code
in char/drm/drm_vm.c and block/z2ram.c).

Improve performance of userspace post receive, post SRQ receive, and

Lockdep warns when userspace creates a QP that uses different CQs for
send completions and receive completions, because both CQs are locked
and their mutexes belong to the same lock class. However, we know
that the mutexes are distinct and the nesting is safe (there is no
possibility of AB-BA deadlock because the mutexes are locked with
down_read()), so annotate the situation with SINGLE_DEPTH_NESTING to
get rid of the lockdep warning.

The SM LID used to send traps to is incorrectly set to port LID. This
is a regression from 2.6.17 -- after a PortInfo MAD is received, no
traps are sent to the SM LID. The traps go to the loopback interface
instead, and are dropped there. The SM LID should be taken from the
sm_lid of the PortInfo response.

Introduce the MTD_STUPID_LOCK flag which indicates that the flash chip is
always locked after power-up, so all sectors need to be unlocked before it
is usable.
If this flag is set, and the chip provides an unlock() operation,
mtd_add_device will unlock the whole MTD device if it's writeable. This
means that non-writeable partitions will stay locked.
Set MTD_STUPID_LOCK in fixup_use_atmel_lock() so that these chips will work
as expected.
