From 3118f1a2f29ae802a334963c2aded87d60bddd56 Mon Sep 17 00:00:00 2001
From: James Hughes <james.hughes@raspberrypi.org>
Date: Wed, 31 Oct 2018 13:00:46 +0000
Subject: [PATCH 148/806] Increase firmware call buffer size to 48 bytes
An assumption was made in commit a1547e0bc that 32 bytes
would be enough data buffer size for all firmware calls. However,
the axi performance monitor driver uses a call with 44 bytes
(RPI_FIRMWARE_GET_PERIPH_REG) to get the VC registers values.
Increase value to 48 to take this in to account.

Date: Tue, 13 Nov 2018 17:27:00 +0000
Subject: [PATCH 206/806] Mailbox firmware calls now use kmalloc (#2749)
A previous change moved away from variable stack
allocation of a data buffer to a fixed maximum size.
However, some mailbox calls use larger data buffers
than the maximum allowed. This change moves from
stack storage to kmalloc to ensure all sizes are
catered for.
