module: show version information for built-in modules in sysfs
Currently only drivers that are built as modules have their versions
shown in /sys/module/<module_name>/version, but this information might
also be useful for built-in drivers as well. This especially important
for drivers that do not define any parameters - such drivers, if
built-in, are completely invisible from userspace.
This patch changes MODULE_VERSION() macro so that in case when we are
compiling built-in module, version information is stored in a separate
section. Kernel then uses this data to create 'version' sysfs attribute
in the same fashion it creates attributes for module parameters.
This commit causes the crash below on m68k (ARAnyM).
Reverting this commit and its dependency
3b90a5b292321b2acac3921f77046ae195aef53f
("module: fix linker error for MODULE_VERSION when !MODULE and CONFIG_SYSFS=n")
makes it boot again.
