Each Synopsys MSI group (32 MSIs) is mapped to a dedicated PCIe
IRQ. Current MSI driver handles only 1 PCIe IRQ. Add support in
PCIe MSI driver to correctly handle multiple Synopsys MSI groups.

Some times the SOC value reported as increasing even though
there is no charger connected to the device. Fix it by correcting

Random sequence cache is precomputed during slab object creation
based up on the object size and no of objects per slab. These could
be changed when flags like SLAB_STORE_USER, SLAB_POISON are updated
from sysfs. So when shuffle_freelist is called during slab_alloc it
uses updated object count to access the precomputed random sequence
cache. This could result in incorrect access of the random sequence
cache which could further result in slab corruption. Fix this by
reinitializing the random sequence cache up on slab object update.

A sample panic trace when write to slab_store_user was attempted.

Usually modules are loaded into small area prior to the kernel
text because they are linked with the kernel using short calls.
Compile-time instrumentation like GCOV or KASAN bloats code a lot,
and as a result huge modules no longer fit into reserved area.

This patch adds option CONFIG_MODULES_USE_VMALLOC which lifts
limitation on amount of loaded modules. It links modules using
long-calls (option -mlong-calls) and loads them into vmalloc area.

In few places exported symbols are called from inline assembly.
This patch adds macro for such call sites: __asmbl and __asmbl_clobber.
Call turns into single 'bl' or sequence 'movw; movt; blx' depending on
context and state of config option.

Unfortunately this option isn't compatible with CONFIG_FUNCTION_TRACER.
Compiler emits short calls to profiling function despite of -mlong-calls.
This is a bug in GCC, but ftrace anyway needs an update to handle this.

For some parallel chargers(SMB1390/SMB1395) temperature and current
reporting is done via same h/w line, this sometimes leads to an unreliable
reporting of SMB DIE health via main charger. Fix this by moving to s/w
based reporting of SMB health by reading the SMB temperature via ADC
channel and comparing it with the predefined thresholds.

For isochronous endpoints with mult less than 2, the
PCM value of the trb->size is set incorrectly.
For case of mult = 1, this is set to 0/-1 and for
mult = 0, this is set to -2.
This is because the initial mult is set to
ep->mult - 1. Fix this by setting the value of
initial value of mult to 2.

There could be a race condition between invoke and accept threads of
CB server. If exit for some reason, accept threads would exit and invoke
thread may be processing a CB req that lands up on wait Q after accept
threads have exited. This could cause invoke thread ot hang on wait Q.
Adding a notification mechanism that would set flag if system is either
shutting down or going to reboot. This would help invoke thread to avoid
wait on Q if system was under shutdown when it was about to land on Q.
