Since the purgatory is a special stand-alone binary, various profiling and sanitizing options must be disabled. Having these options enabled typically will cause dependencies on various special symbols exported by special libs / stubs used by these frameworks. Since the purgatory is special, it is not linked against these stubs causing missing symbols in the purgatory if these options are not disabled. Sync the set of disabled profiling and sanitizing options with that from drivers/firmware/efi/libstub/Makefile, adding -DDISABLE_BRANCH_PROFILING to the CFLAGS and setting: GCOV_PROFILE := n UBSAN_SANITIZE := n This fixes broken references to ftrace_likely_update() when CONFIG_TRACE_BRANCH_PROFILING is enabled and to __gcov_init() and __gcov_exit() when CONFIG_GCOV_KERNEL is enabled.

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.
