seccomp: Replace BUG(!spin_is_locked()) with assert_spin_lock

Current upstream kernel hangs with mips and powerpc targets in
uniprocessor mode if SECCOMP is configured.

Bisect points to commit dbd952127d11 ("seccomp: introduce writer locking").
Turns out that code such as
	BUG_ON(!spin_is_locked(&list_lock));
can not be used in uniprocessor mode because spin_is_locked() always
returns false in this configuration, and that assert_spin_locked()
exists for that very purpose and must be used instead.

xen-netback: Don't deschedule NAPI when carrier off

In the patch called "xen-netback: Turn off the carrier if the guest is not able
to receive" NAPI was descheduled when the carrier was set off. That's
not what most of the drivers do, and we don't have any specific reason to do so
as well, so revert that change.

xen-netfront: Fix handling packets on compound pages with skb_linearize

There is a long known problem with the netfront/netback interface: if the guest
tries to send a packet which constitues more than MAX_SKB_FRAGS + 1 ring slots,
it gets dropped. The reason is that netback maps these slots to a frag in the
frags array, which is limited by size. Having so many slots can occur since
compound pages were introduced, as the ring protocol slice them up into
individual (non-compound) page aligned slots. The theoretical worst case
scenario looks like this (note, skbs are limited to 64 Kb here):
linear buffer: at most PAGE_SIZE - 17 * 2 bytes, overlapping page boundary,
using 2 slots
first 15 frags: 1 + PAGE_SIZE + 1 bytes long, first and last bytes are at the
end and the beginning of a page, therefore they use 3 * 15 = 45 slots
last 2 frags: 1 + 1 bytes, overlapping page boundary, 2 * 2 = 4 slots
Although I don't think this 51 slots skb can really happen, we need a solution
which can deal with every scenario. In real life there is only a few slots
overdue, but usually it causes the TCP stream to be blocked, as the retry will
most likely have the same buffer layout.
This patch solves this problem by linearizing the packet. This is not the
fastest way, and it can fail much easier as it tries to allocate a big linear
area for the whole packet, but probably easier by an order of magnitude than
anything else. Probably this code path is not touched very frequently anyway.

net: bcmgenet: request and enable main clock earlier

bcmgenet_set_hw_params() will read the hardware version and compare it
with the one we are getting from Device Tree. Due to the clock being
enabled too late, bcmgenet_set_hw_params() will cause bus errors since
the GENET hardware block is still gated off by the time
bcmgenet_set_hw_params() is called, this will also make us fail the
version check since we will read the value 0 from the hardware.

Fix this by requesting the clock before the first piece of code that
needs to access hardware register.

net: bcmgenet: correctly suspend and resume PHY device

Make sure that we properly suspend and resume the PHY device when we
enter low power modes. We had two calls to bcmgenet_mii_reset() which
will issue a software-reset to the PHY without using the PHY library,
get rid of them since they are completely bogus and mess up with the PHY
library state. Make sure that we reset the PHY library cached values
(link, pause and duplex) to allow the link adjustment callback to be
invoked when needed.

net: bcmgenet: update UMAC_CMD only when link is detected

When we bring the interface down, phy_stop() will schedule the PHY state
machine to call our link adjustment callback. By the time we do so, we
may have clock gated off the GENET hardware block, and this will cause
bus errors to happen in bcmgenet_mii_setup():

Make sure that we only touch the UMAC_CMD register when there is an
actual link. This is safe to do for two reasons:

- updating the Ethernet MAC registers only make sense when a physical
  link is present
- the PHY library state machine first set phydev->link = 0 before
  invoking phydev->adjust_link in the PHY_HALTED case

net: bcmgenet: correctly resume adapter from Wake-on-LAN

In case we configured the adapter to be a wake up source from
Wake-on-LAN, but we never actually woke up using Wake-on-LAN, we will
leave the adapter in MagicPacket matching mode, which prevents any other
type of packets from reaching the RX engine. Fix this by calling
bcmgenet_power_up() with GENET_POWER_WOL_MAGIC to restore the adapter
configuration in bcmgenet_resume().

The second problem we had was an imbalanced clock disabling in
bcmgenet_wol_resume(), the Wake-on-LAN slow clock is only enabled in
bcmgenet_suspend() if we configured Wake-on-LAN, yet we unconditionally
disabled the clock in bcmgenet_wol_resume().

sparc64: Do not disable interrupts in nmi_cpu_busy()

nmi_cpu_busy() is a SMP function call that just makes sure that all of the
cpus are spinning using cpu cycles while the NMI test runs.

It does not need to disable IRQs because we just care about NMIs executing
which will even with 'normal' IRQs disabled.

It is not legal to enable hard IRQs in a SMP cross call, in fact this bug
triggers the BUG check in irq_work_run_list():

	BUG_ON(!irqs_disabled());

Because now irq_work_run() is invoked from the tail of
generic_smp_call_function_single_interrupt().

sparc64: Fix pcr_ops initialization and usage bugs.

Christopher reports that perf_event_print_debug() can crash in uniprocessor
builds.  The crash is due to pcr_ops being NULL.

This happens because pcr_arch_init() is only invoked by smp_cpus_done() which
only executes in SMP builds.

init_hw_perf_events() is closely intertwined with pcr_ops being setup properly,
therefore:

1) Call pcr_arch_init() early on from init_hw_perf_events(), instead of
   from smp_cpus_done().

2) Do not hook up a PMU type if pcr_ops is NULL after pcr_arch_init().

3) Move init_hw_perf_events to a later initcall so that it we will be
   sure to invoke pcr_arch_init() after all cpus are brought up.

Finally, guard the one naked sequence of pcr_ops dereferences in
__global_pmu_self() with an appropriate NULL check.
