2013-01-04Drivers: parport: remove __dev* attributes.Greg Kroah-Hartman4-55/+50
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

The panic happens since commit 9597abe00c1bab2aedce6b49866bf6d1e81c9eed (sections: fix section conflicts in arch/powerpc), however the root cause of this is that the NULL terminator were not added in commit a4f740cf33f7f6c164bbde3c0cdbcc77b0c4997c (of/flattree: Add of_flat_dt_match() helper function).

2013-01-03powerpc/vdso: Remove redundant locking in update_vsyscall_tz()Shan Hai1-5/+0
The locking in update_vsyscall_tz() is not only unnecessary because the vdso code copies the data unproteced in __kernel_gettimeofday() but also introduces a hard to reproduce race condition between update_vsyscall() and update_vsyscall_tz(), which causes user space process to loop forever in vdso code. The following patch removes the locking from update_vsyscall_tz(). Locking is not only unnecessary because the vdso code copies the data unprotected in __kernel_gettimeofday() but also erroneous because updating the tb_update_count is not atomic and introduces a hard to reproduce race condition between update_vsyscall() and update_vsyscall_tz(), which further causes user space process to loop forever in vdso code. The below scenario describes the race condition, x==0 Boot CPU other CPU proc_P: x==0 timer interrupt update_vsyscall x==1 x++;sync settimeofday update_vsyscall_tz x==2 x++;sync x==3 sync;x++ sync;x++ proc_P: x==3 (loops until x becomes even) Because the ++ operator would be implemented as three instructions and not atomic on powerpc.

commit a99d76f leds: leds-gpio: use gpio_request_one changed the leds-gpio driver to use gpio_request_one() instead of gpio_request() + gpio_direction_output() Unfortunately, it also made a semantic change that breaks the leds-gpio driver. The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | (led_dat->active_low ^ state) Since GPIOF_DIR_OUT is 0, the final flags value will just be the XOR'ed value of led_dat->active_low and state. This value were used to distinguish between HIGH/LOW output initial level and call gpio_direction_output() accordingly. With this new semantic gpio_request_one() will take the flags value of 1 as a configuration of input direction (GPIOF_DIR_IN) and will call gpio_direction_input() instead of gpio_direction_output(). int gpio_request_one(unsigned gpio, unsigned long flags, const char *label) { .. if (flags & GPIOF_DIR_IN) err = gpio_direction_input(gpio); else err = gpio_direction_output(gpio, (flags & GPIOF_INIT_HIGH) ? 1 : 0); .. } The right semantic is to evaluate led_dat->active_low ^ state and set the output initial level explicitly.

Commit 56c176c9cac9 ("UAPI: strip the _UAPI prefix from header guards during header installation") strips the _UAPI prefix from header guards, but only if there's a single space between the cpp directive and the label.

To address this, this patch restores sp->lock as originally implemented by Kosaki Motohiro. In the path where get_vma_policy() is called, it should not be calling sp_alloc() so it is not necessary to treat the PTL specially.
