Subject: [PATCH 3/3] ACPI, APEI, ERST, Fix erst-dbg long record reading issue

From: Chen Gong <gong.chen@...ux.intel.com>

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.
