I seem to have lost this hunk in yesterday's patch. It brings the coming-online CPU's softlockup timer up to date so we don't get false-positive tripups during CPU hot-add. Signed-off-by:

Attached patch fixes invalid pointer arithmetic in DMI code to make onboard device discovery working again. akpm: bug has been present since dmi_find_device() was added in 2.6.14. Affects ipmi only (I think) - the symptoms weren't described. akpm: changed to use pointer arithmetic rather than open-coded sizeof. Signed-off-by:

This patch series creates a strndup_user() function to easy copying C strings from userspace. Also we avoid common pitfalls like userspace modifying the final \0 after the strlen_user(). Signed-off-by:

Make the softlockup detector purely timer-interrupt driven, removing softirq-context (timer) dependencies. This means that if the softlockup watchdog triggers, it has truly observed a longer than 10 seconds scheduling delay of a SCHED_FIFO prio 99 task. (the patch also turns off the softlockup detector during the initial bootup phase and does small style fixes) Signed-off-by:

In filesystems with the meta block group flag on, ext3_bg_num_gdb() fails to report the correct number of blocks used to store the group descriptor backups in a given group. It happens because meta_bg follows a different logic from the original ext3 backup placement in groups multiples of 3, 5 and 7. Signed-off-by:

Andrew Morton authored
At present the kernel doesn't honour an attempt to set RLIMIT_CPU to zero seconds. But the spec says it should, and that's what 2.4.x does. Fixing this for real would involve some complexity (such as adding a new it-has-been-set flag to the task_struct, and testing that everwhere, instead of overloading the value of it_prof_expires). Given that a 2.4 kernel won't actually send the signal until one second has expired anyway, let's just handle this case by treating the caller's zero-seconds as one second.

- Whitespace cleanups - Make that expression comprehensible. There's a potential logic change here: we do the "is it_prof_expires equal to zero" test after converting it to seconds, rather than doing the comparison between raw cputime_t's. But given that it's in units of seconds anyway, that shouldn't change anything.

Third large chunk of code cleanup. The split between this and #3 and #4 is fairly arbitary and due to the message length limit on the list. These patches continue the process of ripping out macros and typedefs while cleaning up lots of 32bit assumptions. Several inlines for compatibility also get removed and that causes a lot of noise.

More header cleanups, strip out typedefs and remove cruft. There are a lot of magic macros that can go and also a great deal of abuse of volatile that is not needed any more as this patch set cleans up the misuse of pointer access to ISA and PCI space. It now builds cleanly on 64bit, although there is more work left to do Signed-off-by:

It appears that console_setup() code only gets compiled into the kernel if CONFIG_PRINTK is enabled. One detrimental side-effect of this is that serial8250_console_setup() never gets invoked when CONFIG_PRINTK is not set, resulting in baud rate not being read/parsed from command line (i.e. console=ttyS0,115200n8 is ignored, at least the baud rate part...) Attached patch moves console_setup() code from inside #ifdef CONFIG_PRINTK to outside (in printk.c), removing dependence on said config. option. Signed-off-by:

I today booted the first time my embedded device using Linux 2.6.15.2, which was booted by pxelinux, which then bootet itself from the nfsroot. This went pretty fine, but when I was reading through Documentation/nfsroot.txt I saw that there are some more modern versions available of loading the kernel and passing parameters. Signed-off-by:

msync() does a strange thing. Essentially: vma = find_vma(); for ( ; ; ) { if (!vma) return -ENOMEM; ... vma = vma->vm_next; } so an msync() request which starts within or before a valid VMA and which ends within or beyond the final VMA will incorrectly return -ENOMEM.

Andrew Morton authored
It seems sensible to perform dirty page throttling in msync: as the application dirties pages we can kick off pdflush early, or even force the msync() caller to perform writeout, or even throttle the msync() caller. The main effect of this is to start disk writeback earlier if we've just discovered that a large amount of pagecache has been dirtied. (Otherwise it wouldn't happen for up to five seconds, next time pdflush wakes up). It also will cause the page-dirtying process to get panalised for dirtying those pages rather than whacking someone else with the problem. We should do this for munmap() and possibly even exit(), too. We drop the mmap_sem while performing the dirty page balancing. It doesn't seem right to hold mmap_sem for that long. Note that this patch only affects MS_ASYNC. MS_SYNC will be syncing all the dirty pages anyway. We note that msync(MS_SYNC) does a full-file-sync inside mmap_sem, and always has. We can fix that up... The patch also tightens up the mmap_sem coverage in sys_msync(): no point in taking it while we perform the incoming arg checking.
