Richard Henderson point out a while back that linker generated symbols
should be declared as: "char _text[]" so that the compiler can't make
assumptions about them sitting in small sections, etc.
Centralize these defintions in asm/sections.h (where some already
are on x86).

Introduce _sinittext and _einittext (cf. _stext and _etext), so kallsyms
includes __init functions.
TODO: Use huffman name compression and 16-bit offsets (see IDE
oopser patch)

This removes the extable list, and the struct exception_table, in
favour of just iterating through the modules. Now all iteration is
within kernel/module.c, this is a fairly trivial cleanup.
|
|
By making module_text_address return the module it found, we
simplify symbol_put_addr significantly.
|
|
Various archs (i386, m68k, s390, s390x, m68k, parisc, um, x86_64)
implement kernel_text_address. Put this in kernel/extable.c, and the
module iteration inside module.c.
Other than cleanliness, this finally allows the module list and lock
to be static to kernel/module.c (you didn't think I actually cared
about those archs did you?)
It also drops the module->init_size to zero when it's discarded, so
bounds checking is simplified (and the /proc/modules size statistic
will be more accurate, too).

This patch combines the common exception table searching functionality
for various architectures, to avoid unneccessary (and currently buggy)
duplication, and so that the exception table list and lock can be kept
private to module.c.
The archs provide "struct exception_table" and "search_extable": the
generic infrastructure drives the rest.

This implements EXPORT_SYMBOL_GPL and MODULE_LICENSE properly (so
restrictions are enforced). Also fixes "proprietory" spelling.

was enabled, so split it up into "extable.c"
