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:

Currently the BKL is used to synchronize access to ioctl32_hash_table in fs/compat.c. It seems that an rwsem would be more appropriate, since this would allow multiple lookups to occur in parallel (and also serve the general good of minimizing use of the BKL). I added lock_kernel()/unlock_kernel() around the call to t->handler when a compatibility handler is found in compat_sys_ioctl() to preserve the expectation that the BKL will be held during driver ioctl operations. It should be safe to do lock_kernel() while holding ioctl32_sem because of the magic BKL sleep semantics. Signed-off-by:

This patch adds common nls_tolower, nls_toupper and nls_strnicmp helpers to nls.h and uses them in various filesystems instead of local duplicates. The situation for ncpfs isn't as nice as it allows to compile without nls support even if the kernel has CONFIG_NLS set, so we need wrappers there. Signed-off-by:

The kernel contains an optimization that skips the linked list walk in get_tgid_list for the common case of sequential accesses. Unfortunately the optimization is buggy (missing NULL pointer check for the result of find_task_by_pid) and broken (actually - broken twice: the tgid value that is stored in f_version is always 0 because tgid is overwritten when the string is created and additionally the common case is not filldir < 0, it's running out of nr_tgids). The attached patch fixes these bugs.

Fix the do_generic_file_read()-reads-one-page-too-many-bug for the fifth time. This patch combines the best features from Nick's patch and also makes index and end_index consistent. (i.e index 'n' covers n*PAGE_SIZE to ((n+1)PAGE_SIZE)-1. I did not feel comfortable with the way index and end_index represented different ranges. It was like comparing apples with oranges.

On x86 and x86-64, setting up to run a signal handler clears the single-step bit (TF) in the processor flags before starting the handler. This makes sense when a process is handling its own SIGTRAPs. But when TF is set because PTRACE_SINGLESTEP was used, and that call specified a handled signal so the handler setup is happening, it doesn't make so much sense. When the debugger stops to show you a signal about to be delivered, and that signal should be handled, and then you do step or stepi, you expect to see the signal handler code. In fact, the signal handler runs to completion and then you see the single-step trap at the resumed code instead of seeing the handler. This patch changes signal handler setup so that when TF is set and the thread is under ptrace control, it synthesizes a single-step trap after setting up the PC and registers to start the handler. This makes that PTRACE_SINGLESTEP not strictly a "step", since it actually runs no user instructions at all. But it is definitely what a debugger user wants, so that single-stepping always stops and shows each and every instruction before it gets executed. Signed-off-by:

In 2.4, strace will show you all bogus system calls a process tries. In 2.6, it only shows you stubs < __NR_syscalls, and there is no tracing stop for large bogus system call numbers. I can't see why this was changed, so I am assuming it was accidental. This patch restores the expected behavior that syscall tracing shows every bogus syscall attempt. Signed-off-by:
