Subject: PASEMI: PA6T board doesn't boot with the RC1 of kernel 4.2 anymore
Date: Fri, 10 Jul 2015 08:51:25 +0200 [thread overview]
Message-ID: <559F6B6D.2000002@xenosoft.de> (raw)
In-Reply-To: <559EF557.4040403@xenosoft.de>
Hi All,
The first bad commit:
http://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?id=0d0b4c866bcce647f40d73efe5e90aeeb079050a
I replaced the following irq files with the old kernel 4.1 irq files:
~/Downloads/linux-4.2/linux-4.2-nemo$ cp
/home/christian/Downloads/linux-4.1/linux-4.1/include/linux/irq.h
include/linux/irq.h
~/Downloads/linux-4.2/linux-4.2-nemo$ cp
/home/christian/Downloads/linux-4.1/linux-4.1/include/linux/irqdesc.h
include/linux/irqdesc.h
~/Downloads/linux-4.2/linux-4.2-nemo$ cp
/home/christian/Downloads/linux-4.1/linux-4.1/kernel/irq/internals.h
kernel/irq/internals.h
~/Downloads/linux-4.2/linux-4.2-nemo$ cp
/home/christian/Downloads/linux-4.1/linux-4.1/kernel/irq/irqdesc.c
kernel/irq/irqdesc.c
~/Downloads/linux-4.2/linux-4.2-nemo$ cp
/home/christian/Downloads/linux-4.1/linux-4.1/kernel/irq/irqdomain.c
kernel/irq/irqdomain.c
~/Downloads/linux-4.2/linux-4.2-nemo$ cp
/home/christian/Downloads/linux-4.1/linux-4.1/kernel/irq/manage.c
kernel/irq/manage.c
~/Downloads/linux-4.2/linux-4.2-nemo$ cp
/home/christian/Downloads/linux-4.1/linux-4.1/kernel/irq/proc.c
kernel/irq/proc.c
I compiled the RC1 of kernel 4.2 with these old irq source code today.
I'm happy it boots. :-)
Rgds,
Christian
