Texas Instruments' K3 generation SoCs has an IP Interrupt Router
that does allows for redirection of input interrupts to host
interrupt controller. Interrupt Router inputs are either from a
peripheral or from an Interrupt Aggregator which is another
interrupt controller.
Configuration of the interrupt router registers can only be done by
a system co-processor and the driver needs to send a message to this
co processor over TISCI protocol.
Add support for Interrupt Router driver over TISCI protocol.

thunderx_gpio_irq_{request,release}_resources apis are trying to
{request,release} resources on parent interrupt. There are default
apis doing the same. Use the default parent apis instead of writing
the same code snippet.

Each resource with in the device can be uniquely identified as defined
by TISCI. Since this is generic across the devices, resource allocation
also can be made generic instead of each client driver handling the
resource. So add helper apis to manage the resource.

TISCI provides support for getting the resources(IRQ, RING etc..)
assigned to a specific device. These resources can be handled by
the client and in turn sends TISCI cmd to configure the resources.
It is very important that client should keep track on usage of these
resources.
Add support for TISCI commands to get resource ranges.

TISCI has been updated to have support for Resource management(like
interrupts etc..). And there can be multiple device instances of a
resource type in a SoC. So every driver corresponding to a resource type
should get a TISCI handle so that it can make TISCI calls. And each
DT node corresponding to a device should exist under its corresponding
bus node as per the SoC architecture.
But existing apis in TISCI library assumes that all TISCI users are
child nodes of TISCI. Which is not true in the above case. So introduce
(devm_)ti_sci_get_by_phandle() apis that can be used by TISCI users
to get TISCI handle using of phandle property.

Using list_add + list_sort to insert an element and keeping the list
sorted is a somewhat blunt instrument; one can find the right place to
insert in fewer lines of code than the cmp callback uses. Moreover,
walking the entire list afterwards to merge adjacent ranges is
overkill, since we know that only the just-inserted element may be
merged with its neighbours.

There's no reason to ask kmalloc() to zero the allocation, since all
the fields get initialized immediately afterwards. Except that there's
also not any reason to initialize the ->entry member, since the

There's no reason to do the allocation of the new lpi_range inside the
lpi_range_lock. One could change the code to avoid the allocation
altogether in case the freed range can be merged with one or two
existing ranges (in which case the allocation would naturally be done
under the lock), but it's probably not worth complicating the code for
that.

This irqchip driver uses the hwspinlock framework (coprocessor HW regs
access concurrency) for the stm32mp1-exti device.
Hence, this driver needs to handle the hwspinlock driver dependency
using the deferred probe mechanism which requires to move this driver
into a platform one with a probe() ops.
This applies only for the device which is "st,stm32mp1-exti" compatible,
the management of the other devices (st,stm32h7-exti / st,stm32-exti) is
kept unchanged (use IRQCHIP_DECLARE)

If interrupts are enabled for a non-root GIC device that uses the
gic-pm driver, when system suspend occurs, the current interrupt
state is not saved and restored correctly and so interrupts do not
work again on resuming the system. Add a late suspend handler to
save and restore the state for these devices.

gic-pm driver is using pm-clk framework to manage clock resources, where
clocks remain always ON. This happens on Tegra devices which use BPMP
co-processor to manage the clocks. Calls to BPMP are always blocking and
hence it is necessary to enable/disable clocks during prepare/unprepare
phase respectively. When pm-clk is used, prepare count of clock is not
balanced until pm_clk_remove() happens. Clock is prepared in the driver
probe() and thus prepare count of clock remains non-zero, which in turn
keeps clock ON always.
Please note that above mentioned behavior is specific to Tegra devices
using BPMP for clock management and this should not be seen on other
devices. Though this patch uses clk_bulk APIs to address the mentioned
behavior, this works fine for all devices.
To simplify gic_get_clocks() API is removed and instead probe can do
necessary setup.

It is useful to print which interrupt controllers are registered in the
system and which parent IRQ they use, especially given that L2 interrupt
controllers do not call request_irq() on their parent interrupt and do
not appear under /proc/interrupts for that reason.
We used to print the base register address virtual address which had
little value, use %pOF to print the path to the Device Tree node which
maps to the physical address more easily and is what people need to
troubleshoot systems.

Merge page ref overflow branch.
Jann Horn reported that he can overflow the page ref count with
sufficient memory (and a filesystem that is intentionally extremely
slow).
Admittedly it's not exactly easy. To have more than four billion
references to a page requires a minimum of 32GB of kernel memory just
for the pointers to the pages, much less any metadata to keep track of
those pointers. Jann needed a total of 140GB of memory and a specially
crafted filesystem that leaves all reads pending (in order to not ever
free the page references and just keep adding more).
Still, we have a fairly straightforward way to limit the two obvious
user-controllable sources of page references: direct-IO like page
references gotten through get_user_pages(), and the splice pipe page
duplication. So let's just do that.
* branch page-refs:
fs: prevent page refcount overflow in pipe_buf_get
mm: prevent get_user_pages() from overflowing page refcount
mm: add 'try_get_page()' helper function
mm: make page ref count overflow check tighter and more explicit
|
|
Change pipe_buf_get() to return a bool indicating whether it succeeded
in raising the refcount of the page (if the thing in the pipe is a page).
This removes another mechanism for overflowing the page refcount. All
callers converted to handle a failure.

If the page refcount wraps around past zero, it will be freed while
there are still four billion references to it. One of the possible
avenues for an attacker to try to make this happen is by doing direct IO
on a page multiple times. This patch makes get_user_pages() refuse to
take a new page reference if there are already more than two billion
references to the page.

This is the same as the traditional 'get_page()' function, but instead
of unconditionally incrementing the reference count of the page, it only
does so if the count was "safe". It returns whether the reference count
was incremented (and is marked __must_check, since the caller obviously
has to be aware of it).
Also like 'get_page()', you can't use this function unless you already
had a reference to the page. The intent is that you can use this
exactly like get_page(), but in situations where you want to limit the
maximum reference count.
The code currently does an unconditional WARN_ON_ONCE() if we ever hit
the reference count issues (either zero or negative), as a notification
that the conditional non-increment actually happened.
NOTE! The count access for the "safety" check is inherently racy, but
that doesn't matter since the buffer we use is basically half the range
of the reference count (ie we look at the sign of the count).

We have a VM_BUG_ON() to check that the page reference count doesn't
underflow (or get close to overflow) by checking the sign of the count.
That's all fine, but we actually want to allow people to use a "get page
ref unless it's already very high" helper function, and we want that one
to use the sign of the page ref (without triggering this VM_BUG_ON).
Change the VM_BUG_ON to only check for small underflows (or _very_ close
to overflowing), and ignore overflows which have strayed into negative
territory.

but it's a kind of usual pattern: now it contains a collection of ASoC
fixes, and nothing to worry too much.
The fixes for ASoC core (DAPM, DPCM, topology) are all small and just
covering corner cases. The rest changes are driver-specific, many of
which are for x86 platforms and new drivers like STM32, in addition to
the usual fixups for HD-audio"
