We must create the server before we can call init_socks or check the
number of threads.
Symptoms were a NULL pointer dereference in nfsd_svc(). Problem
identified by Jeff Layton.
Also fix a minor cleanup-on-error case in nfsd_startup().

A regression of building without CONFIG_HW_CONSOLE was introduced with
commit b45cfba4e9005d64d419718e7ff7f7cab44c1994 (vt,console,kdb:
implement atomic console enter/leave functions).
ERROR: "con_debug_enter" [drivers/serial/kgdboc.ko] undefined!
ERROR: "vc_cons" [drivers/serial/kgdboc.ko] undefined!
ERROR: "fg_console" [drivers/serial/kgdboc.ko] undefined!
ERROR: "con_debug_leave" [drivers/serial/kgdboc.ko] undefined!
When there is no HW console the con_debug_enter and con_debug_leave
functions should have no code.

KVM ended up having to put a pretty ugly wrapper around set_64bit()
in order to get the type right. Now set_64bit() takes the expected
u64 type, and this wrapper can be cleaned up.

The root cause is that ring_buffer_read_page() may read out of page
boundary, because the boundary checking is done after reading. This is
fixed via doing boundary checking before reading.

Commit 69309a059075 ("x86, asm: Clean up and simplify set_64bit()")
sanitized the x86-64 types to set_64bit(), and incidentally resulted in
warnings like
drivers/pci/intr_remapping.c: In function 'modify_irte':
drivers/pci/intr_remapping.c:314: warning: passing argument 1 of 'set_64bit' from incompatible pointer type
arch/x86/include/asm/cmpxchg_64.h:6: note:expected 'volatile u64 *' but argument is of type 'long unsigned int *'
It turns out that the change to set_64bit() really does clean up things,
and the PCI intr_remapping.c file did a rather ugly cast in order to
avoid warnings with the previous set_64bit() type model.
Removing the ugly cast fixes the warning, and makes everybody happy and
expects a set_64bit() to take the logical "u64 *" argument.

spin_is_locked() can return zero on some (UP?)
configurations because locks don't exist, and
that causes an endless amount of warnings. Use
lockdep_assert_held() instead, which has two
advantages:
1) it verifies the current task is holding
the lock or mutex
2) it compiles away completely when lockdep
is not enabled

The ibmvfc driver was incorrectly obtaining a scsi_target pointer
from an fc_rport. The way it is coded ensures that ibmvfc's

and abort task set as appropriate. Without this patch,
fast_io_fail_tmo is broken for ibmvfc.

Commit 43c8da907ccc656935d1085701f4db83385d8a59 introduced a race
condition which can occur when adding/deleting rports. There are
two possible threads now that can be deleting rports in the ibmvfc
driver, which can result in list_del being called twice, resulting
in an oops. This patch adds a new state to the ibmvfc_target struct
to indicate the target has been removed from the list and is in
the process of being deleted.

Outstanding mailbox commands, have no way to recover on f/w hung, and we
timeout on waiting for mbx response. This in turn affects the recovery process
as follows:
- We might already be in dpc while waiting for mbx to complete, so recovery for
that pci function will never get invoked. Reset Timeout (10 sec) is far less
than mbx timeout (30 sec).
- Other mbx cmds will get stuck due to serial mbx access.
Solution is to identify fw-hung scenario and handle outstanding mbx commands to
have an early-exit instead of waiting for response.
Other mbx commands waiting for access will also do an early-exit if fw-hung is
still applicable.

Also, changed boundary checking from size of total
structure to verification that we received the amount of
data needed to cache inernally. This change will provide
compatibility with mbx_sys_info structure sizes in both
older and newer firmware versions.
