When call0 userspace ABI support by probing is enabled instructions that cause illegal instruction exception when PS.WOE is clear are retried with PS.WOE set before calling c-level exception handler. Record user pc at which PS.WOE was set in the fast exception handler and clear PS.WOE in the c-level exception handler if we get there from the same address.

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.
