[PATCH 02/19] ACPI, APEI, ERST, Fix erst-dbg long record reading issue

From: Len Brown
Date: Tue Aug 02 2011 - 18:15:17 EST


From: Chen Gong <gong.chen@xxxxxxxxxxxxxxx>

When we debug ERST table with erst-dbg, if the error record in ERST
table is too long(>4K), it can't be read out. So this patch increases
the buffer size to 16K to ensure such error records can be read from
ERST table.
