* tricky one: hisax sectionsAl Viro2008-11-301-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | a) hisax_init_pcmcia() needs to be defined only if we have CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared __devinit. b) HiSax_inithardware() can go __init c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card(): checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card); The problem with it is that * hisax_cs_setup_card() is __devinit * hisax_register() is not * hisax_cs_setup_card() is a switch from hell, calling a lot of setup_some_weirdcard() depending on card->typ. _These_ are also __devinit. However, in hisax_register() we have card->typ equal to ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind all that crap, just do nothing and return 2". So we add a trimmed-down callback doing just that and passed to checkcard() by hisax_register(). _This_ is non-init (we can stand the impact on .text size).

* isdn: remove extra byteswap in isdn_net_ciscohdlck_slarp_send_replyHarvey Harrison2008-11-171-2/+4
| | | | | | | | | | commit a144ea4b7a13087081ab5402fa9ad0bcfd249e67 [IPV4]: annotate struct in_ifaddr Missed this extra byteswap as the isdn inlines hide the htonl inside put_u32 which causes an extra byteswap on little-endian arches.
