Since we set up device wake-up interrupts as pinctrl-single
interrupts, we now must use the standard request_irq and
related functions to manage them.
If the pin interrupts are enabled for some pins at boot,
the wake-up events can show up as constantly pending
at least on omaps and will hang the system unless the related
device driver clears the event at the device.
To fix this, let's clear the interrupt flags during init,
and print out a warning so the board maintainers can update
their drivers to do proper request_irq for the driver specific
wake-up events.

Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print
functions like kernel does" added a extra trace_seq helper to process
string arguments like the kernel does it. But the difference between the
kernel and the userspace library is that the kernel's trace_seq structure
has a static allocated buffer. The userspace one has a dynamically
allocated one. It requires a trace_seq_destroy(), otherwise it produces
a nasty memory leak.

The return value for pevent_filter_match() is suppose to return FILTER_NONE
if the event doesn't have a filter, and FILTER_NOEXIST if there is no filter
at all. But the change 41e12e580a7 "tools lib traceevent: Refactor
pevent_filter_match() to get rid of die()" replaced the return value
with PEVENT_ERRNO__* values and added "backward compatibility" macros
that used the old names. Unfortunately, the NOEXIST and NONE macros were
swapped, and this broke users that use the old return names.

If I unplug the eDP monitor, the BIOS of my machine will enable the
VDD bit, then when the driver loads it will think VDD is enabled. It
will detect that the eDP is not enabled and return false from
intel_edp_init_connector. This will trigger a call to
edp_panel_vdd_off_sync(), which trigger a WARN saying that the
refcount of the power domain is less than zero.
The problem happens because the driver gets a refcount whenever it
enables the VDD bit, and puts the refcount whenever it disables the
VDD bit. But on this case, the BIOS enabled VDD, so all we do is to
call put() without calling get() first, so the code added is there to
make sure we always have the get() in case the BIOS enabled the bit.
This regression was introduced in

... our current modeset code isn't good enough yet to handle this. The
scenario is:
1. BIOS sets up a cloned config with lvds+external screen on the same
pipe, e.g. pipe B.
2. We read out that state for pipe B and assign the gmch_pfit state to
it.
3. The initial modeset switches the lvds to pipe A but due to lack of
atomic modeset we don't recompute the config of pipe B.
-> both pipes now claim (in the sw pipe config structure) to use the
gmch_pfit, which just won't work.

Fix e26a9e00afc482b971afcaef1db8c9034d4d6d7c 'ARM: Better
virt_to_page() handling' replaced __pv_phys_offset with
__pv_phys_pfn_offset. Also note that size of __pv_phys_offset
was quad but size of __pv_phys_pfn_offset is word. Instruction
that used to update __pv_phys_offset which address is in r6
had to update low word of __pv_phys_offset so it used #LOW_OFFSET
macro for store offset. Now when size of __pv_phys_pfn_offset is
word, no difference between little endian and big endian should
exist - i.e no offset should be used when __pv_phys_pfn_offset
is stored.
Note that for little endian image proposed change is noop,
since in little endian case #LOW_OFFSET is defined 0 anyway.

The switcher should not depend on MAX_CLUSTER to determine ifit should
be activated or not. In a multiplatform kernel binary it is possible to
have dual-cluster and quad-cluster platforms configured in. In that case
MAX_CLUSTER which is a build time limit should be 4 and that shouldn't
prevent the switcher from working if the kernel is booted on a b.L
dual-cluster system.
In bL_switcher_halve_cpus() we already have a runtime validation check
to make sure we're dealing with only two clusters, so booting on a quad
cluster system will be caught and switcher activation aborted.
However, the b.L switcher must ensure the MCPM layer is initialized on
the booted hardware before doing anything. The mcpm_is_available()
function is added to that effect.

fixup_user_fault() is used by the futex code when the direct user access
fails, and the futex code wants it to either map in the page in a usable
form or return an error. It relied on handle_mm_fault() to map the
page, and correctly checked the error return from that, but while that
does map the page, it doesn't actually guarantee that the page will be
mapped with sufficient permissions to be then accessed.
So do the appropriate tests of the vma access rights by hand.
[ Side note: arguably handle_mm_fault() could just do that itself, but
we have traditionally done it in the caller, because some callers -
notably get_user_pages() - have been able to access pages even when
they are mapped with PROT_NONE. Maybe we should re-visit that design
decision, but in the meantime this is the minimal patch. ]

There were occasional ADSP crash during reboot testing:
[ 11.883364] BUG: unable to handle kernel paging request at ffffc90121700000

[ 11.883405] Oops: 0002 [#1] SMP
[ 11.886418] gsmi: Log Shutdown Reason 0x03
The virtual address, ffffc90121700000, was out of range. The virtual
address is calculated by adding LPE base address with an offset:
sst_memcpy32(dsp->addr.lpe + data->offset, data->data, data->size);
The offset is calculated in sst_byt_parse_module, by subtraction of
two virtual addresses dsp->addr.fw_ext and dsp->addr.lpe:
block_data.offset = block->ram_offset + (dsp->addr.fw_ext - dsp->addr.lpe);
These virtual addresses are assigned by kernel from ioremap:
sst->addr.lpe = ioremap(pdata->lpe_base, pdata->lpe_size);
sst->addr.fw_ext = ioremap(pdata->fw_base, pdata->fw_size);
In current driver code, offset is defined as unsigned int32:
struct sst_module_data {
...
u32 offset; /* offset in FW file */
};
Most of the time kernel assigned virtual addresses with addr.fw_ext
greater than addr.lpe. But sometimes it was the other way round.
Fix the problem by declaring offset as signed int32_t.

Implement a recv budget so that in cases of high traffic we still allow other

Without this, we can encounter a host of issues during high wireless traffic
reception depending on system load including rcu stall's detected (ARM),
soft lockups, failure to service critical tasks such as watchdog resets,
and triggering of the tx stuck tasklet.
The same thing was proposed previously by Ben:
