Higher value allows xhci core to moderate interrupts resulting
in fewer interrupts from xhci core. This results in lower CPU
utilization during peak throughput scenarios.

It is only necessary to poll the power gate retention status register
when disallowing LDO retention mode. Once the power control override
register is cleared, any power domain is allowed to utilize LDO
retention. Therefore, polling of APCC_PGS_RET_STATUS must only be done
when VDD_APCC is scaled below retention voltage plus LDO headroom
voltage and the voltage is not sufficient to safely support power
domains using LDO retention.

For CONFIG_KALLSYMS, we keep two symbol tables and two string tables.
There's one full copy, marked SHF_ALLOC and laid out at the end of the
module's init section. There's also a cut-down version that only
contains core symbols and strings, and lives in the module's core
section.
After module init (and before we free the module memory), we switch
the mod->symtab, mod->num_symtab and mod->strtab to point to the core
versions. We do this under the module_mutex.
However, kallsyms doesn't take the module_mutex: it uses
preempt_disable() and rcu tricks to walk through the modules, because
it's used in the oops path. It's also used in /proc/kallsyms.
There's nothing atomic about the change of these variables, so we can
get the old (larger!) num_symtab and the new symtab pointer; in fact
this is what I saw when trying to reproduce.
By grouping these variables together, we can use a
carefully-dereferenced pointer to ensure we always get one or the
other (the free of the module init section is already done in an RCU
callback, so that's safe). We allocate the init one at the end of the
module init section, and keep the core one inside the struct module
itself (it could also have been allocated at the end of the module
core, but that's probably overkill).

platform_driver get probed, the channel has opened and glink is notified
