drivers/rtc/rtc-tegra.c: set irq name as device name

The irq name of tegra rtc shows as "rtc alarm" which actually does not
reflect the name related to driver.

Passing the device name to have the irq names with driver name.

CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows
to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME.  This means if CONFIG_PM
is used to protect system sleep callbacks then it may end up unreferenced
if only runtime PM is enabled.  Hence protecting sleep callbacks with
CONFIG_PM_SLEEP.

11 years agoinit: scream bloody murder if interrupts are enabled too early
Steven Rostedt [Mon, 29 Apr 2013 23:18:18 +0000 (16:18 -0700)]
init: scream bloody murder if interrupts are enabled too early

As I was testing a lot of my code recently, and having several
"successes", I accidentally noticed in the dmesg this little line:

  start_kernel(): bug: interrupts were enabled *very* early, fixing it

Sure enough, one of my patches two commits ago enabled interrupts early.
The sad part here is that I never noticed it, and I ran several tests with
ktest too, and ktest did not notice this line.

What ktest looks for (and so does many other automated testing scripts) is
a back trace produced by a WARN_ON() or BUG().  As a back trace was never
produced, my buggy patch could have slipped into linux-next, or even
worse, mainline.

Adding a WARN(!irqs_disabled()) makes this bug a little more obvious:

  PID hash table entries: 4096 (order: 3, 32768 bytes)
  __ex_table already sorted, skipping sort

Do you see it?

The original version of this patch just slapped a WARN_ON() in there and
kept the printk().  Ard van Breemen suggested using the WARN() interface,
which makes the code a bit cleaner.

Also, while examining other warnings in init/main.c, I found two other
locations that deserve a bloody murder scream if their conditions are hit,
and updated them accordingly.

Oleg Nesterov [Mon, 29 Apr 2013 23:18:10 +0000 (16:18 -0700)]
argv_split(): teach it to handle mutable strings

argv_split() allocates argv[count_argc(str)] array and assumes that it
will find the same number of arguments later.  This is obviously wrong if
this string can be changed, say, by sysctl.

With this patch argv_split() kstrndup's the whole string and does not
split it, we simply replace the spaces with zeroes and keep the allocated
memory in argv[-1] for argv_free(arg).

We do not use argv[0] because:

- str can be all-spaces or empty. In fact this case is fine,
  we could kfree() it before return, but:

- str can have a space at the start, and we can not rely on
  kstrndup(skip_spaces(str)) because it can equally race if
  this string is mutable.

Also, simplify count_argc() and kill the no longer used skip_arg().
