Section mismatches can now result in build failures. As result, cris:allnoconfig fails to build as follows. WARNING: modpost: Found 7 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' FATAL: modpost: Section mismatches detected. Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them. Part of the problem is that references from .text to .init.text are not permitted, and such references are used in cris startup code. Since references from .head.text to .init.text are permitted, move cris startup code to a new section .head.text.

|
|
* It is VERY DANGEROUS to fiddle around with the symbols in this
|
|
* script. It is for example quite vital that all generated sections
|
|
* that are used are actually named here, otherwise the linker will
|
|
* put them at the end, where the init stuff is which is FREED after
|
|
* the kernel has booted.
