When printing the signal context's PC, we use a "%lx" format specifier,
which matches the common userland (glibc's) definition of uint64_t as an
"unsigned long". However the structure in question is defined in a
kernel uapi header, which uses a self defined __u64 type, and the arm64
kernel headers define this using "int-ll64.h", so it becomes an
"unsigned long long". This mismatch leads to the usual compiler warning.
The common fix would be to use "PRIx64", but because this is defined by
the userland's toolchain libc headers, it wouldn't match as well. Since
we know the exact type of __u64, just use "%llx" here instead, to silence
this warning.
This also fixes a more severe typo: "$lx" is not a valid format
specifier.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
