For all syscalls in 32-bit compat mode on 64-bit kernels the upper 32-bits of the 64-bit registers are zeroed out, so a negative 32-bit signed value will show up as positive 64-bit signed value. This behaviour breaks the io_pgetevents_time64() syscall which expects signed 64-bit values for the "min_nr" and "nr" parameters. Fix this by switching to the compat_sys_io_pgetevents_time64() syscall, which uses "compat_long_t" types for those parameters.

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.
