Arnd Bergmann reported that a randconfig build was failing with the
following link error:
built-in.o: member arch/x86/kernel/time.o in archive is not an object
It turns out the link failed because the time.o file had been corrupted
by objtool:
nm: arch/x86/kernel/time.o: File format not recognized
In certain rare cases, when a .o file's ORC table is very small, the
.data section size doesn't change because it's page aligned. Because
all the existing sections haven't changed size, libelf doesn't detect
any section header changes, and so it doesn't update the section header
table properly. Instead it writes junk in the section header entries
for the new ORC sections.
Make sure libelf properly updates the section header table by setting
the ELF_F_DIRTY flag in the top level elf struct.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
