Avoid forcing use of the no-op scheduler for UBD; this may uncover some bugs in the UBD driver, and in fact uml-ubd-no-empty-queue.patch is needed to make this sure. But as of now, no other bugs have been discovered, so this should be safe. Signed-off-by:

Avoid using, in the UBD driver, the elv_queue_empty function. It's for the block layer only; in fact, the Anticipatory Scheduler can return NULL with elv_next_request() even if the queue is not empty, because it waits for the process to send another request before seeking on the disk. In fact, if (with uml-ubd-any-elevator) we let UBD use any scheduler, elevator=as will make the UBD driver Oops, if we don't have this patch. Signed-off-by:

I noticed a large machine was doing about 400,000 context switches per second when oprofile was enabled. Upon closer inspection it looks like we were rearming the buffer sync timer without modifying the expire time. Now that we have schedule_delayed_work_on I believe we can remove the timer completely. Each cpu should be offset by 1 jiffy so they dont all fire at the same time. I bumped DEFAULT_TIMER_EXPIRE from 2 to 10 times a second to be sure we reap cpu buffers. With the following patch the same large machine gets about 4000 context switches per second. Signed-off-by:

The problem here is, finished_one_bio() shouldn't call aio_complete() since no work has been done. I have a fix for this - can you verify this ? I am not really comfortable with this "tweaking". (I am not really sure about IO errors like EIO etc. - if they can lead to calling aio_complete() twice) Fix is to call aio_complete() ONLY if there is something to report. Note the we don't update dio->result with any error codes from get_user_pages(), they just passed as "ret" value from do_direct_IO(). Signed-off-by:

This adds module_init(xxxfb_init) in all drivers. For drivers with xxxfb_setup(), this patch also adds a 'xxxfb_setup(fb_get_options("xxxfb"))' prior to initialization. Signed-off-by:Antonino Daplas <adaplas@pol.net> Signed-off-by:

This patch probably deserves discussion among developers. Currently, the framebuffer system is initialized in a roundabout manner. First, drivers/char/mem.c calls fbmem_init(). fbmem_init() will then iterate over an array of individual drivers' xxxfb_init(), then each driver registers its presence back to fbmem. During console_init(), drivers/char/vt.c will call fb_console_init(). fbcon will check for registered drivers, and if any are present, will call take_over_console() in drivers/char/vt.c. This patch changes the initialization sequence so it proceeds in this manner: Each driver has its own module_init(). Each driver calls register_framebuffer() in fbmem.c. fbmem.c will then notify fbcon of the driver registration. Upon notification, fbcon calls take_over_console() in vt.c. The following are the changes brought about by this patch: - Each subsystem (fbcon, fbmem, xxxfb) will have their own module_init. Thus, explicit calls to each subsystem's init functions are eliminated. - The struct fb_drivers array in fbmem.c can be removed. This slashes around 400 lines in fbmem.c - Parsing of kernel boot options were done by fbmem.c calling each driver's xxxfb_setup() function. Because this is not possible with this patch, drivers can choose to either: - have their own __setup() routine - call fb_get_options("xxxfb") and pass the return value to xxxfb_setup(). This is to maintain compatibility with the 'video=xxxfb:<options>' semantics. - Getting a framebuffer console will occur a bit late during the boot process since the initialization sequence will depend upon the link order. So, 'video/' is moved up in drivers/Makefile, shortly after 'pci/' - Because driver initialization will be dependent on the link order, hardware that depends on other subsystems (agpgart, usb, serial, etc) may choose to initialize after the subsystems they depend on.

- This fixes another regression from 2.4. If fbcon is compiled statically, and the framebuffer driver is compiled as a module, doing a 'modprobe xxxfb' does nothing to the console. This has generated numerous bug reports from users. With this patch, fbmem will notify fbcon upon driver registration allowing fbcon to take over the console. - This also fixes con2fbmap not working if fbcon is compiled as a module using the same mechanism as described above.

This patch speeds up scrolling of tdfxfb by maximizing var->yres_virtual so tdfxfb uses SCROLL_PAN_MOVE instead of SCROLL_REDRAW. This is true whether CONFIG_FB_3DFX_ACCEL is set or not. This problem was reported by Paolo Ornati <ornati@fastwebnet.it> who also made substantial contributions to solve this problem. This patch also fixes compile errors when CONFIG_FB_3DFX_ACCEL is false. Signed-off-by:

The following patch switches arch/ppc/boot over from using its own version of zlib to the code found under lib/zlib_inflate. In conjunction with the previous two patches, the size of the resulting images isn't noticably different. But this does have the advantage of removing another copy of zlib from the kernel, and I believe this allows for lib/inflate.c to go away (as that's basically what ppc used to use). Signed-off-by:

The different stack frame layout for packed stacks broke cpu hotplug. Recreate the initial stack frame of the idle thread for offline cpus coming back online. Reenable interrupts after loading the initial registers. In addition this patch contains two more bug fixes: a typo for 64 bit (__SMALL_STACK_SIZE vs. __SMALL_STACK) and show_trace didn't show a trace if for task == NULL. Signed-off-by:
