Commit a53e35db

 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Playing with IP-O-IB interface can trigger a warning message:
"ib0: Failed to modify QP to ERROR state" to be logged.
This happens when the QP is in IB_QPS_RESET state and the stack
is trying to transition it to IB_QPS_ERR state in ipoib_ib_dev_stop().

According to the IB spec, Table 91 - "QP State Transition Properties"
it looks like the transition from reset to error is valid:

Transition: Any State to Error

Optional Attributes: None allowed

This patch allows the transition and quiets the message.

Currently the RoCE GID management uses the ib_wq to do add and delete new GIDs
according to the netdev events.

The ib_wq isn't an ordered workqueue and thus two work elements can be executed
concurrently which will result in unexpected behavior and inconsistency of the
GIDs cache content.

Example:
ifconfig eth1 11.11.11.11/16 up

This command will invoke the following netdev events in the following order:
1. NETDEV_UP
2. NETDEV_DOWN
3. NETDEV_UP

If (2) and (3) will be executed concurrently or in reverse order, instead of
having a new GID with 11.11.11.11 IP, we will end up without any new GIDs.

Commit 21caf2fc ("mm: teach mm by current context info to not do I/O
during memory allocation") added the memalloc_noio_(save|restore) functions
to enable people to modify the MM behavior by disabling I/O during memory
allocation. This was further extended in Fixes: 934f3072 ("mm: clear
__GFP_FS when PF_MEMALLOC_NOIO is set"). memalloc_noio_* functions prevent
allocation paths recursing back into the filesystem without explicitly
changing the flags for every allocation site.

However the IPoIB hasn't been keeping up with the changes and missed
completely these memalloc_noio_* calls. This led to update of
allocation site with special QP creation flag, see commit 09b93088


("IB: Add a QP creation flag to use GFP_NOIO allocations"), while this
flag is supported by small number of drivers in IB stack.

Let's change it by updating to memalloc_noio_* calls and allow

Several variables had their types changed from unsigned long to u32,
but the printk()-style format to print them wasn't updated, leading to:

    arch/blackfin/kernel/flat.c: In function 'bfin_get_addr_from_rp':
    arch/blackfin/kernel/flat.c:35:3: warning: format '%lx' expects argument of type 'long unsigned int', but argument 2 has type 'u32' [-Wformat]
    arch/blackfin/kernel/flat.c: In function 'bfin_put_addr_at_rp':
    arch/blackfin/kernel/flat.c:80:3: warning: format '%lx' expects argument of type 'long unsigned int', but argument 2 has type 'u32' [-Wformat]
