Subject: [RFC PATCH v1 0/3] Enable CONFIG_VMAP_STACK on the 8xx
Date: Tue, 11 Dec 2018 11:23:50 +0000 (UTC) [thread overview]
Message-ID: <cover.1544519035.git.christophe.leroy@c-s.fr> (raw)
The purpose of this serie is to enable CONFIG_VMAP_STACK on the 8xx.
I'm sending it now to get early feedback if any.
For the time being, there is no proper handling of stack overflow.
This serie applies on the top of the serie "powerpc: Switch to CONFIG_THREAD_INFO_IN_TASK"
Christophe Leroy (3):
powerpc/32: prepare for CONFIG_VMAP_STACK
powerpc/8xx: Use alternative scratch registers in DTLB miss handler
