Accessing non-existent PMU registers causes an SError, halting the
system.
regmap can help us with that by allowing to pass the list of valid
registers as part of the config during creation. When this driver
creates a new regmap itself rather than relying on
syscon_node_to_regmap(), it's therefore easily possible to hook in
custom access tables for valid read and write registers.
Specifying access tables avoids SErrors for invalid registers and
instead the regmap core can just return an error. Outside drivers, this
is also helpful when using debugfs to access the regmap.
Make it possible for drivers to specify read and write tables to be
used on creation of the secure regmap by adding respective fields to
struct exynos_pmu_data. Also add kerneldoc to same struct while
updating it.

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().

Pull x86 cleanups from Borislav Petkov:
- Simplify inline asm flag output operands now that the minimum
compiler version supports the =@ccCOND syntax
- Remove a bunch of AS_* Kconfig symbols which detect assembler support
for various instruction mnemonics now that the minimum assembler
version supports them all
- The usual cleanups all over the place
