uevent_seqnum and uevent_helper are only defined if CONFIG_HOTPLUG=y,
CONFIG_NET=n.(I stole this back from Greg's tree - it makes allnoconfig work).

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: Davi Arnaut

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: Ingo Molnar

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: Glauber de Oliveira Costa

Document the fact that setrlimit(RLIMIT_CPU) doesn't return error codes when
it should. I don't think we can fix this without a 2.7.x..Cc: Martin Schwidefsky

Signed-off-by: Linus Torvalds -
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.Cc: Martin Schwidefsky

- 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.Cc: Martin Schwidefsky

Drivers have no business looking at the task list and thus using this lock.
The only possibly modular users left are:arch/ia64/kernel/mca.c
drivers/edac/edac_mc.c
fs/binfmt_elf.cwhich I'll send out fixes for soon.

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.Signed-off-by: Alan Cox

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

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.

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.Fix.
