ksym_tracer: Remove trace_stat

trace_stat is problematic. Don't use it, use seqfile instead.

This fixes a race that reading the stat file is not protected by
any lock, which can lead to use after free.

tracing: Fix setting tracer specific options

The function __set_tracer_option() takes as its last parameter a
"neg" value. If set it should negate the value of the option.

The trace_options_write() passed the value written to the file
which is what the new value needs to be set as. But since this
is not the negative, it never sets the value.

Linus Torvalds [Sat, 12 Dec 2009 22:46:33 +0000]
[BKL] add 'might_sleep()' to the outermost lock taker

As shown by the previous patch (6698e3472: "tty: Fix BKL taken under a
spinlock bug introduced in the BKL split") the BKL removal is prone to
some subtle issues, where removing the BKL in one place may in fact make
a previously nested BKL call the new outer call, and then prone to nasty
deadlocks with other spinlocks.

In general, we should never take the BKL while we're holding a spinlock,
so let's just add a "might_sleep()" to it (even though the BKL doesn't
technically sleep - at least not yet), and we'll get nice warnings the
next time this kind of problem happens during BKL removal.

omap3: Fix OMAP35XX_REV macros

In original implementation, the revision passed to
these macros contained revision number in lower nibble.

But, later the revision bits (OMAP_REVBITS_XX) were
defined to use omap_revision[15:08] where revision
number is containied in higher nibble.

This patch updates the macros; else incorrect revision
