2d1e991060 scsi: qedf: Make qedf_execute_tmf() non-preemptible 
[ Upstream commit 0d8b637c9c5eeaa1a4e3dfb336f3ff918eb64fec ]

Stop calling smp_processor_id() from preemptible code in
qedf_execute_tmf90.  This results in BUG_ON() when running an RT kernel.

[ 659.343280] BUG: using smp_processor_id() in preemptible [00000000] code: sg_reset/3646
[ 659.343282] caller is qedf_execute_tmf+0x8b/0x360 [qedf]

34444ff18b scsi: qedf: Ensure the copied buf is NUL terminated 
[ Upstream commit d0184a375ee797eb657d74861ba0935b6e405c62 ]

Currently, we allocate a count-sized kernel buffer and copy count from
userspace to that buffer. Later, we use kstrtouint on this buffer but we
don't ensure that the string is terminated inside the buffer, this can
lead to OOB read when using kstrtouint. Fix this issue by using
memdup_user_nul instead of memdup_user.

Fixes: 61d8658b4a43 ("scsi: qedf: Add QLogic FastLinQ offload FCoE driver framework.")
