Then enable KPROBES (or XMON).
Then put an #ifdef CONFIG_PPC_FPU in ldstfp.S.

I had to give up. Without the CONFIG_PPC_FPU it compiles fine for
It's common sense that when we should do change to driver ring
desc/buffer etc only after 'stop/shutdown' the device. When we
do change while devices/driver is running, kernel oops occur:

Add a call to of_node_put in the error handling code following a call to
of_find_node_by_type.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
//
@r exists@
local idexpression x;
expression E,E1,E2;
statement S;
@@
*x =
(of_find_node_by_path
|of_find_node
Add a call to of_node_put in the error handling code following a call to
of_find_compatible_node or of_find_node_by_type.
This patch also substantially reorganizes the error handling code in the
function, to that it is possible first to jump to code that frees qe_port
and then to jump to code that

Hi all,
I am new to linux device driver development. I have to develop a SPI driver
for MPC8377 processor based board. Right now I don't have a that board
ready(but I have the MPC837xERDB with me), so I was thinking of developing
and testing it on the RDB. But in MPC837xERDB, I don't have an SPI
Since the cpu accounting code uses the hypervisor dispatch trace log
now when CONFIG_VIRT_CPU_ACCOUNTING = y, the previous commit disabled
access to it via files in the /sys/kernel/debug/powerpc/dtl/ directory
in that case. This restores those files.
To do this, we now have a hook that the cpu ac
clk_get() should return an ERR_PTR value on error, not NULL.
