We need to read the sizes of the signal context frames as part of parsing the overall signal context in parse_user_sigframe(). In the cases where we defer frame specific parsing to other functions those functions (other than the recently added TPIDR2 parser) reread the size and validate the version they read, opening the possibility that the value may change. Avoid this possibility by passing the size read in parse_user_sigframe() through user_ctxs and referring to that. For consistency we move the size check for the TPIDR2 context into the TPIDR2 parsing function. Note that for SVE, ZA and ZT contexts we still read the size again but after this change we no longer use the value, further changes will avoid the read.

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 Restructured Text 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.
