4a93adcbd2 of: Add wrappers to match root node with OF device ID tables
Several drivers duplicate same code for getting reference to the root
node, matching it against 'struct of_device_id' table and getting out
the match data from the table entry.

There is a of_machine_compatible_match() wrapper but it takes array of
strings, which is not suitable for many drivers since they want the
driver data associated with each compatible.

Add two wrappers, similar to existing of_device_get_match_data():
1. of_machine_device_match() doing only matching against 'struct
   of_device_id' and returning bool.
2. of_machine_get_match_data() doing the matching and returning
   associated driver data for found compatible.

6ba51b7b34 of/irq: Handle explicit interrupt parent
If an interrupt controller is used as a proxy, it may have an
"interrupt-parent" property, but lack "interrupts" and
"interrupts-extended" properties.  In that case, the "interrupt-parent"
property in the interrupt controller node is ignored, causing the
interrupt controller to fail to probe, and leading to system boot
failures or crashes.

Fix this by also considering an explicit "interrupt-parent" property in
the interrupt controller node itself.

It is a requirement that DT overlays in the kernel are applied at build
time to a base DTB in order to validate they can be applied and to
validate them against the DT schemas. DT overlays on their own may be
incomplete and can't be validated.

Add a kbuild check so this doesn't have to be checked and fixed

1b1f04d827 of/irq: Ignore interrupt parent for nodes without interrupts
The Devicetree Specification states:

    The root of the interrupt tree is determined when traversal of the
    interrupt tree reaches an interrupt controller node without an
    interrupts property and thus no explicit interrupt parent.

However, of_irq_init() gratuitously assumes that a node without
interrupts has an actual interrupt parent if it finds an
interrupt-parent property higher up in the device tree.  Hence when such
a property is present (e.g. in the root node), the root interrupt
controller may not be detected as such, causing a panic:

    OF: of_irq_init: children remain, but no parents
    Kernel panic - not syncing: No interrupt controller found.

Commit e91033621d ("of/irq: Use interrupts-extended to find
parent") already fixed a first part, by checking for the presence of an
interrupts-extended property.  Fix the second part by only calling
of_irq_find_parent() when an interrupts property is present.

67029a49db tracing fixes for v6.18:
The previous fix to trace_marker required updating trace_marker_raw
 as well. The difference between trace_marker_raw from trace_marker
 is that the raw version is for applications to write binary structures
 directly into the ring buffer instead of writing ASCII strings.
 This is for applications that will read the raw data from the ring
 buffer and get the data structures directly. It's a bit quicker than
 using the ASCII version.
 
 Unfortunately, it appears that our test suite has several tests that
 test writes to the trace_marker file, but lacks any tests to the
 trace_marker_raw file (this needs to be remedied). Two issues came
 about the update to the trace_marker_raw file that syzbot found:
 
 - Fix tracing_mark_raw_write() to use per CPU buffer
 
   The fix to use the per CPU buffer to copy from user space was needed for
   both the trace_maker and trace_maker_raw file.
 
   The fix for reading from user space into per CPU buffers properly fixed
   the trace_marker write function, but the trace_marker_raw file wasn't
   fixed properly. The user space data was correctly written into the per CPU
   buffer, but the code that wrote into the ring buffer still used the user
   space pointer and not the per CPU buffer that had the user space data
   already written.
 
 - Stop the fortify string warning from writing into trace_marker_raw
 
   After converting the copy_from_user_nofault() into a memcpy(), another
   issue appeared. As writes to the trace_marker_raw expects binary data, the
   first entry is a 4 byte identifier. The entry structure is defined as:
 
   struct {
 	struct trace_entry ent;
 	int id;
 	char buf[];
   };
 
   The size of this structure is reserved on the ring buffer with:
 
     size = sizeof(*entry) + cnt;
 
   Then it is copied from the buffer into the ring buffer with:
 
     memcpy(&entry->id, buf, cnt);
 
   This use to be a copy_from_user_nofault(), but now converting it to
   a memcpy() triggers the fortify-string code, and causes a warning.
 
   The allocated space is actually more than what is copied, as the cnt
   used also includes the entry->id portion. Allocating sizeof(*entry)
   plus cnt is actually allocating 4 bytes more than what is needed.
 
   Change the size function to:
 
     size = struct_size(entry, buf, cnt - sizeof(entry->id));
 
   And update the memcpy() to unsafe_memcpy().
