An allmodconfig build of sparc32 resulted in several warnings: WARNING: modpost: EXPORT symbol "empty_zero_page" [vmlinux] version generation failed, symbol will not be versioned. Is "empty_zero_page" prototyped in <asm/asm-prototypes.h>? WARNING: modpost: EXPORT symbol "__udelay" [vmlinux] version generation failed, symbol will not be versioned. Is "__udelay" prototyped in <asm/asm-prototypes.h>? WARNING: modpost: EXPORT symbol "__ndelay" [vmlinux] version generation failed, symbol will not be versioned. Is "__ndelay" prototyped in <asm/asm-prototypes.h>? WARNING: modpost: EXPORT symbol "__ashldi3" [vmlinux] version generation failed, symbol will not be versioned. Is "__ashldi3" prototyped in <asm/asm-prototypes.h>? WARNING: modpost: EXPORT symbol "__ashrdi3" [vmlinux] version generation failed, symbol will not be versioned.

Is "__lshrdi3" prototyped in <asm/asm-prototypes.h>? And later a lot of warnings like this: WARNING: modpost: "__udelay" [kernel/locking/locktorture.ko] has no CRC! WARNING: modpost: "__udelay" [kernel/rcu/rcutorture.ko] has no CRC! WARNING: modpost: "__udelay" [kernel/rcu/rcuscale.ko] has no CRC! WARNING: modpost: "__udelay" [kernel/rcu/refscale.ko] has no CRC! WARNING: modpost: "__ndelay" [kernel/rcu/refscale.ko] has no CRC! WARNING: modpost: "__udelay" [kernel/time/test_udelay.ko] has no CRC! WARNING: modpost: "__udelay" [kernel/scftorture.ko] has no CRC! WARNING: modpost: "__ashrdi3" [fs/quota/quota_tree.ko] has no CRC! WARNING: modpost: "__ashldi3" [fs/ext4/ext4.ko] has no CRC! The fix was, as hinted, to add missing prototypes to asm-prototypes.h. For the __*di3 functions add the prototypes direct to the asm-prototypes.h file. Some of the symbols were already declared, so pulled in the relevant headers (delay.h, pgtable.h). The include files was alphabetically sorted to make the list somehow readable. The .S files exporting the symbols do not include asm-prototypes.h, so they need to be explicit rebuild to generate symbol versioning. One or more of the generic headers pulled in by asm-prototypes.h did not support being used from .S files, so adding asm-prototypes.h as an include file was not an option.

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 reStructuredText 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.
