From 162a7e7500f9664636e649ba59defe541b7c2c60 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Tue, 24 May 2011 17:13:20 -0700 Subject: printk: allocate kernel log buffer earlier On larger systems, because of the numerous ACPI, Bootmem and EFI messages, the static log buffer overflows before the larger one specified by the log_buf_len param is allocated. Minimize the overflow by allocating the new log buffer as soon as possible. On kernels without memblock, a later call to setup_log_buf from kernel/init.c is the fallback.
