[PATCH] larger IO bitmaps
The previous discussion was started here: http://www.uwsg.iu.edu/hypermail/linux/kernel/0211.0/0477.html but in 2.4 times this was kind of problematic. Now, with the lazy bitmap allocation and per-CPU TSS, this will really not drain any resources I think. 8K TSS increase and 8K per process *that does ioperm()* - I think it is not very bad. The reasons why I need that, are described in the URL above. Basically this will allow to use full-screen VESA under dosemu (without LFB though), and this may be also helpfull for the XFree project and some other projects: http://www.uwsg.iu.edu/hypermail/linux/kernel/9807.1/1079.htmlSigned-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
