The rationale for removing the check is only correct for rulesets
generated by ip(6)tables.

In iptables, a jump can only occur to a user-defined chain, i.e.
because we size the stack based on number of user-defined chains we
cannot exceed stack size.

However, the underlying binary format has no such restriction,
and the validation step only ensures that the jump target is a
valid rule start point.

IOW, its possible to build a rule blob that has no user-defined
chains but does contain a jump.

If this happens, no jump stack gets allocated and crash occurs
because no jumpstack was allocated.

If the list search in sg_get_rq_mark() fails to find a valid request, we
return a bogus element. This then can later lead to a GPF in
sg_remove_scat().

So don't return bogus Sg_requests in sg_get_rq_mark() but NULL in case
the list search doesn't find a valid request.

commit c52232a4 upstream.

On CPU hotunplug the enqueued timers of the unplugged CPU are migrated to a
live CPU. This happens from the control thread which initiated the unplug.

If the CPU on which the control thread runs came out from a longer idle
period then the base clock of that CPU might be stale because the control
thread runs prior to any event which forwards the clock.

In such a case the timers from the unplugged CPU are queued on the live CPU
based on the stale clock which can cause large delays due to increased
granularity of the outer timer wheels which are far away from base:;clock.

But there is a worse problem than that. The following sequence of events
illustrates it:

 - CPU0 timer1 is queued expires = 59969 and base->clk = 59131.

   The timer is queued at wheel level 2, with resulting expiry time = 60032
   (due to level granularity).

 - CPU1 enters idle @60007, with next timer expiry @60020.

 - CPU0 is hotplugged at @60009

 - CPU1 exits idle and runs the control thread which migrates the
   timers from CPU0

   timer1 is now queued in level 0 for immediate handling in the next
   softirq because the requested expiry time 59969 is before CPU1 base->clk
   60007

 - CPU1 runs code which forwards the base clock which succeeds because the
   next expiring timer. which was collected at idle entry time is still set
   to 60020.

   So it forwards beyond 60007 and therefore misses to expire the migrated
   timer1. That timer gets expired when the wheel wraps around again, which
   takes between 63 and 630ms depending on the HZ setting.

Address both problems by invoking forward_timer_base() for the control CPUs
timer base. All other places, which might run into a similar problem
(mod_timer()/add_timer_on()) already invoke forward_timer_base() to avoid
that.

On GMU recovery failure, kgsl clears the GMU_FAULT bit
and also restores the kgsl state to orginal state from
which GMU/GPU wake up was triggered to make sure any
attempt to wake GMU/GPU after this is treated as a fresh
start/hard reset. But on recovery failure, GMU HS, clocks
and IRQ are still ON/enabled because of which any attempt
of GMU/GPU wakeup results in multiple warnings from GMU
start as HS, clocks and IRQ are still ON while doing a
fresh start i.e. wake up from SLUMBER.

Suspend the GMU on recovery failure to make sure next
attempt to wake up GMU/GPU is indeed a fresh start/
hard reset.

Kgsl driver polls GMU for fence status to become zero in case
it was one in IRQ handler and prints "AHB fence stuck in ISR"
error log in case it doesn't happen in multiple retries. Add a
small delay between two retries to make sure GMU firmware gets
sufficient time to abort power collapse. This will avoid this
error prints in scenarios where waiting loop finish much faster
and GMU is still in process of aborting power collapse. This
will also reduce number of retries.

Also, dump register GMU_AO_RBBM_INT_UNMASKED_STATUS_SHADOW as
part of error message to identify the unhandled IRQ when this
error happens.

RSCC wake-up sequence should only be triggered if RSCC

RSCC sleep sequence was done or not and trigger sleep
and wake-up sequence based on this flag to make they
are always balanced.
