[PATCH] alpha: fix IRQ handling lockup

2006-03-10T03:47:37Z

Fix a lockup which was introduced during the conversion to the generic IRQ framework. Cc: Richard Henderson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] alpha: set cpu_possible_map much earlier

2006-02-08T15:57:37Z

All the percpu data structure walkers want cpu_possible_map to be initialized early, but alpha instead populated "hwrpb_cpu_present_mask" early in setup_smp(), and then initialized cpu_possible_map only much later. Thanks go to Heiko Carstens and Dipankar Sarma for noticing. This fixes it and we can get rid of hwrpb_cpu_present_mask entirely. Signed-off-by: Linus Torvalds

[PATCH] alpha show_interrups() trashes argument

2006-02-01T16:53:21Z

This is a bug found by cpminer. The show_interrupts function reuses i as a for loop counter, and therefore trashes its contents, which are needed later. (akpm: rename local `i' to `irq', use for_each_inline_cpu()) Signed-off-by: Eric Sesterhenn Cc: Richard Henderson Cc: Ivan Kokshaysky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] alpha: Fix getxpid on alpha so it works for threads

2006-02-01T16:53:21Z

While looking in the code I discovered that alpha has fallen behind because it doesn't use sys_getppid. The problem is that it doesn't follow the task struct to the task_group_leader. Acked-by: Richard Henderson Cc: Ivan Kokshaysky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] vfs: *at functions: core

2006-01-19T03:20:29Z

Here is a series of patches which introduce in total 13 new system calls which take a file descriptor/filename pair instead of a single file name. These functions, openat etc, have been discussed on numerous occasions. They are needed to implement race-free filesystem traversal, they are necessary to implement a virtual per-thread current working directory (think multi-threaded backup software), etc. We have in glibc today implementations of the interfaces which use the /proc/self/fd magic. But this code is rather expensive. Here are some results (similar to what Jim Meyering posted before). The test creates a deep directory hierarchy on a tmpfs filesystem. Then rm -fr is used to remove all directories. Without syscall support I get this: real 0m31.921s user 0m0.688s sys 0m31.234s With syscall support the results are much better: real 0m20.699s user 0m0.536s sys 0m20.149s The interfaces are for obvious reasons currently not much used. But they'll be used. coreutils (and Jeff's posixutils) are already using them. Furthermore, code like ftw/fts in libc (maybe even glob) will also start using them. I expect a patch to make follow soon. Every program which is walking the filesystem tree will benefit.

[PATCH] alpha: task_stack_page()

[PATCH] alpha: task_thread_info()

[PATCH] dump_thread() cleanup

2006-01-10T16:01:25Z

) From: Adrian Bunk - create one common dump_thread() prototype in kernel.h - dump_thread() is only used in fs/binfmt_aout.c and can therefore be removed on all architectures where CONFIG_BINFMT_AOUT is not available Signed-off-by: Adrian Bunk Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
