X-Git-Tag: v2.6.26-rc1~1146^2~3^2~1 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=41bd26d67c41e325c6b9e56aadfe9dad8af9a565;p=linux-2.6 [IA64] Correct pernodesize calculation. A simple fix. The existing pernodesize reservation is not taking into account a second array of pg_data_t structures. This is normally not important because the PAGE_ALIGN macro reserves adequate space. I made the compute_pernodesize steps in the same order as the fill_pernode steps to make the correlation more clear.
