Subject: [PATCH AUTOSEL 4.14 16/16] parisc: Bump 64-bit IRQ stack size to 64 KB
Date: Wed, 24 Feb 2021 07:55:13 -0500	[thread overview]
Message-ID: <20210224125514.483935-16-sashal@kernel.org> (raw)
In-Reply-To: <20210224125514.483935-1-sashal@kernel.org>

From: John David Anglin <dave.anglin@bell.net>

[ Upstream commit 31680c1d1595a59e17c14ec036b192a95f8e5f4a ]

Bump 64-bit IRQ stack size to 64 KB.

I had a kernel IRQ stack overflow on the mx3210 debian buildd machine.  This patch increases the
64-bit IRQ stack size to 64 KB.  The 64-bit stack size needs to be larger than the 32-bit stack
size since registers are twice as big.
