Subject: x86: Introduce text_poke_smp_batch() for batch-code modifying
X-Git-Tag: v2.6.38-rc1~490^2~46
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7deb18dcf0478940ac979de002db1ed8ba6531dc;p=pandora-kernel.git

x86: Introduce text_poke_smp_batch() for batch-code modifying

Introduce text_poke_smp_batch(). This function modifies several
text areas with one stop_machine() on SMP. Because calling
stop_machine() is heavy task, it is better to aggregate
text_poke requests.

( Note: I've talked with Rusty about this interface, and
  he would not like to expand stop_machine() interface, since
  it is not for generic use. )
