Subject: [PATCH 0/7] Unify <linux/export.h> and <asm/export.h>, remove EXPORT_DATA_SYMBOL()


This patch set refactors EXPORT_SYMBOL, <linux/export.h> and <asm/export.h>.

You can still put EXPORT_SYMBOL() in *.S file, very close to the definition,
but you do not need to care about whether it is a function or a data.
Remove EXPORT_DATA_SYMBOL().



Masahiro Yamada (7):
  modpost: fix section mismatch check for exported init/exit sections
  modpost: put get_secindex() call inside sec_name()
  kbuild: generate struct kernel_symbol by modpost
  ia64,export.h: replace EXPORT_DATA_SYMBOL* with EXPORT_SYMBOL*
  checkpatch: warn if <asm/export.h> is included
  modpost: merge sym_update_namespace() into sym_add_exported()
  modpost: use null string instead of NULL pointer for default namespace
