Deferred probe usually runs only on pinned kworkers, which might take
longer time if a device contains multiple sub-devices. One such case
is of sound card on mobile devices, where we have good number of
mixers and controls per mixer.
We observed boot up improvement - deferred probes take ~600ms when bound
to little core kworker and ~200ms when deferred probe is queued on
unbound wq. This is due to scheduler moving the worker running deferred
probe work to big CPUs. Without this change, we see the worker is running
on LITTLE CPU due to affinity.
Since kworker runs deferred probe of several devices, the locality may
not be important. Also, init thread executing driver initcalls, can
potentially migrate as it has cpu affinity set to all cpus.In addition
to this, async probes use unbounded workqueue. So, using unbounded wq for
deferred probes looks to be similar to these w.r.t. scheduling behavior.

In commit 731d2da95e ("ANDROID: usb: host: export xhci symbols for
ring management") xhci_address_device() is exported, but there is no
function prototype in xhci.h so that it can actually be called properly.
To resolve this, add the correct function prototype.
Based on a larger patch from Daehwan Jung, but split out into an
individual one by Greg.

There could be a scenario where we define some region
in normal memory and use them store to logs which is later
retrieved by bootloader during warm reset.
In this scenario, we wanted to treat this memory as normal
cacheable memory instead of default behaviour which
is an overhead. Making it cacheable could improve
performance.
This commit gives control to change mem_type from Device
tree, and also documents the value for normal memory.

linux/usb/pd.h has a bunch of timers for which the Type-C spec defines
a range of values. These values have to be tuned based on the latency
observed in a specific architecture. However, linux opensource sets
them to a specific value without providing a mechanism to set board
specific values. While a generic way is figured out, a vendor hook
is needed in the interim.
For instance, tCCDebounce can have a value between 100msec - 200msec.

A vendor hook is added in post_init_entity_util_avg before
a new cfs task's util is attached to cfs_rq's util so that
vendors can gather and modify se's information to modify
scheduling behavior and DVFS as they want.
trace_android_rvh_new_task_stats is not a proper hook because
it is called after the task's util is attached to cfs_rq's util,
which means updating cfs_rq's sched_avg and DVFS request are done.

Move the call to ufshcd_prepare_lrbp_crypto() to before
trace_android_vh_ufs_prepare_command() rather than after.
This allows trace_android_vh_ufs_prepare_command() to adjust the crypto
keyslot number in order to support nonstandard hardware that numbers the
crypto keyslots as 1..N instead of 0..N-1 as expected.
Alternatively we could add a hook just for remapping the keyslot number.
But it seems better to just use the existing prepare_command hook.
This should be folded into
ANDROID-scsi-ufs-add-a-hook-to-prepare-command.patch.

Collect the time when each allocation is freed, to help with memory
analysis with kdump/ramdump. Add the timestamp also in the page_owner
debugfs file and print it in dump_page().
Having another timestamp when we free the page helps for debugging page
migration issues. For example both alloc and free timestamps being the
same can gave hints that there is an issue with migrating memory, as
opposed to a page just being dropped during migration.

If there are errors during swap read or write, they can easily fill the
log buffer and remove any previous messages that might be useful for
debugging, especially on systems that rely for logging only on the kernel
ring-buffer.
For example, on a systems using zram as swap, we are more likely to see
any page allocation errors preceding the swap write errors if the alerts
are ratelimited.

This partially reverts commit 882213990d32 ("xen: fix p2m size in dom0
for disabled memory hotplug case")
There's no need to special case XEN_UNPOPULATED_ALLOC anymore in order
to correctly size the p2m. The generic memory hotplug option has
already been tied together with the Xen hotplug limit, so enabling
memory hotplug should already trigger a properly sized p2m on Xen PV.
Note that XEN_UNPOPULATED_ALLOC depends on ZONE_DEVICE which pulls in
MEMORY_HOTPLUG.
Leave the check added to __set_phys_to_machine and the adjusted
comment about EXTRA_MEM_RATIO.

syzbot found UBSAN: shift-out-of-bounds in ext4_mb_init [1], when
1 << sbi->s_es->s_log_groups_per_flex is bigger than UINT_MAX,
where sbi->s_mb_prefetch is unsigned integer type.
32 is the maximum allowed power of s_log_groups_per_flex. Following if
check will also trigger UBSAN shift-out-of-bound:
if (1 << sbi->s_es->s_log_groups_per_flex >= UINT_MAX) {
So I'm checking it against the raw number, perhaps there is another way
to calculate UINT_MAX max power. Also use min_t as to make sure it's
uint type.
