mips: fix build of vmlinux.lds

2009-11-10T00:22:47+00:00

commit d71789b6fa37c21ce5eb588d279f57904a62e7e2 upstream.

Commit 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 ("arm, cris, mips,
sparc, powerpc, um, xtensa: fix build with bash 4.0") removed a few
CPPFLAGS with vital include paths necessary to build vmlinux.lds
on MIPS, and moved the calculation of the 'jiffies' symbol
directly to vmlinux.lds.S but forgot to change make ifdef/... to
cpp macros.

arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0

2009-10-22T22:11:51+00:00

commit 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 upstream.

Albin Tonnerre  reported:

    Bash 4 filters out variables which contain a dot in them.
    This happends to be the case of CPPFLAGS_vmlinux.lds.
    This is rather unfortunate, as it now causes
    build failures when using SHELL=/bin/bash to compile,
    or when bash happens to be used by make (eg when it's /bin/sh)

Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.

This is also nice cleanup as we move the information out where
it is used.

Notes for the different architectures touched:

arm - we use an already exported symbol
cris - we use a config symbol aleady available
       [Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
       Added a few variables to CPPFLAGS - they are only used by
       the linker script.
       [Not build tested]
powerpc - removed assignment that is not needed
          [not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation
         [not build tested]

MIPS: Fix loading of modules with unresolved weak symbols

2009-08-03T16:52:42+00:00

Loading of modules with unresolved weak symbols fails on MIPS
since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.

Modules: handle symbols that have a zero value

The module subsystem cannot handle symbols that are zero.  If symbols
are present that have a zero value then the module resolver prints out a
message that these symbols are unresolved.

We have to use IS_ERR_VALUE() to check that a symbol has been resolved
or not.
