2005-11-04[ALSA] seq-timer: restrict timer frequenciesClemens Ladisch
Modules: ALSA sequencer When no default timer frequency has been set, initialize_timer() just uses the maximum frequency supported by the timer, which is ridiculously high on 96 kHz timers. This patch introduces a default frequency of 1000 Hz for this case, and makes sure that a frequency set by the user isn't too high. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-11-04[ALSA] timer: formatting changesClemens Ladisch
Modules: Timer Midlevel Split or rewrite lines that are longer than 80 characters, and remove whitespaces at the end of lines. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-11-04[ALSA] timer: remove list_entry() type castsClemens Ladisch
Modules: Timer Midlevel The return value of list_entry() already has the type from the second argument, so we don't need to typecase it again. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-11-04[ALSA] timers: add module refcounting for global timersClemens Ladisch
Modules: RTC timer driver,Timer Midlevel Add a module pointer to the timer structure and use it for refcounting instead of the card's module pointer to prevent the global timer modules (rtctimer and hpetimer) from being removed while in use. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-11-04[ALSA] timer: fix timer instance memory allocation checksClemens Ladisch

Modules: Documentation,PCM Midlevel,Timer Midlevel,ALSA Core Use the standard getnstimeofday() function instead of ALSA's own one. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-11-04[ALSA] Remove snd_runtime_check() macroTakashi Iwai
Remove snd_runtime_check() macro. This macro worsens the readability of codes. They should be either normal if() or removable asserts. Also, the assert displays stack-dump, instead of only the last caller pointer. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-11-04[ALSA] sequencer: remove superfluous function parameterClemens Ladisch
Modules: ALSA sequencer Remove the last parameter of snd_seq_timer_set_tick_resolution() because it is always one. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-11-04[ALSA] rtctimer: optimize module parameter validationClemens Ladisch
Modules: RTC timer driver The check whether rtctimer_freq is a power of two can be done easier with a simple bit operation. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-11-04[ALSA] rtctimer: remove superfluous rtc_inc variableClemens Ladisch
Modules: RTC timer driver The rtc_inc variable is never used outside the interrupt handler, and is always one where it matters, so we can just remove it. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2005-10-29[PATCH] core remove PageReservedNick Piggin
Remove PageReserved() calls from core code by tightening VM_RESERVED handling in mm/ to cover PageReserved functionality. PageReserved special casing is removed from get_page and put_page. All setting and clearing of PageReserved is retained, and it is now flagged in the page_alloc checks to help ensure we don't introduce any refcount based freeing of Reserved pages. MAP_PRIVATE, PROT_WRITE of VM_RESERVED regions is tentatively being deprecated. We never completely handled it correctly anyway, and is be reintroduced in future if required (Hugh has a proof of concept). Once PageReserved() calls are removed from kernel/power/swsusp.c, and all arch/ and driver code, the Set and Clear calls, and the PG_reserved bit can be trivially removed. Last real user of PageReserved is swsusp, which uses PageReserved to determine whether a struct page points to valid memory or not. This still needs to be addressed (a generic page_is_ram() should work). A last caveat: the ZERO_PAGE is now refcounted and managed with rmap (and thus mapcounted and count towards shared rss). These writes to the struct page could cause excessive cacheline bouncing on big systems. There are a number of ways this could be addressed if it is an issue.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-07-27[PATCH] clean up inline static vs static inlineJesper Juhl
`gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.
