kallsyms is not completely in address order.
In find_entire_kern_cb(), calculate the kernel end from the maximum
address not the last symbol.
Example:
Before:
$ sudo cat /proc/kallsyms | grep ' [twTw] ' | tail -1
ffffffffc00b8bd0 t bpf_prog_6deef7357e7b4530 [bpf]
$ sudo cat /proc/kallsyms | grep ' [twTw] ' | sort | tail -1
ffffffffc15e0cc0 t iwl_mvm_exit [iwlmvm]
$ perf.d093603a05aa record -v --kcore -e intel_pt// --filter 'filter *' -- uname |& grep filter
Address filter: filter 0xffffffff93200000/0x2ceba000
After:
$ perf.8fb0f7a01f8e record -v --kcore -e intel_pt// --filter 'filter *' -- uname |& grep filter
Address filter: filter 0xffffffff93200000/0x2e3e2000

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 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.
