This patch introduces a kzalloc wrapper and converts kernel/ to use it. It
saves a little program text.

sysfs: fix the rest of the kernel so if an attribute doesn't
implement show or store method read/write will return
-EIO instead of 0 or -EINVAL or -EPERM.

there seems to be a bug, at least for me, in kernel/param.c for arrays with
.num == NULL. If .num == NULL, the function param_array_set() uses &.max
for the call to param_array(), wich alters the .max value to the number of
arguments. The result is, you can't set more array arguments as the last
time you set the parameter.
example:
# a module 'example' with
# static int array[10] = { 0, };
# module_param_array(array, int, NULL, 0644);
$ insmod example.ko array=1,2,3
$ cat /sys/module/example/parameters/array
1,2,3
$ echo "4,3,2,1" > /sys/module/example/parameters/array
$ dmesg | tail -n 1
kernel: array: can take only 3 arguments

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
