tty_register_driver already calls tty_register_device so there is no need
to do it in hvc_console. Besides, it oopses when we do that.

Thanks to Stephen Hemminger for pointing out how obsolete modules.txt is.

modules.txt contains mainly ancient information which is replicated
in the kconfig help message, README, makefile.txt or the modprobe manual
page.  The only part which is not covered elsewhere is the "building
external modules" which is still being debated (and belongs under the
kbuild docs).  kmod.txt reference removed from index, too.

pci_device_id can not be marked __devinitdata,
was re-added with last update by accident.

This fills in the ELF EI_OSABI field.  This doesn't matter for most
architectures, but PA-RISC uses the Linux flavour of the ABI (since HPUX
uses the None flavour).

Compiler warning due to missing equal sign.

From: Andrew Theurer <habanero@us.ibm.com>

This change:
http://linux.bkbits.net:8080/linux-2.5/diffs/kernel/sched.c@1.202

does not seem to make sense:

#define CAN_MIGRATE_TASK(p,rq,this_cpu)					\
	((!idle || (jiffies - (p)->last_run > cache_decay_ticks)) &&    \
		!task_running(rq, p) &&					\
			cpu_isset(this_cpu, (p)->cpus_allowed))

It should be just the opposite; an idle cpu should be able to have a more
aggressive steal, and a busy cpu should not.

From: Matt Mackall <mpm@selenic.com>

The new locking in the random driver is consuming 60% of CPU resources in
Anton's monster power5 boxes.


Basically, when the primary pool is 7/8th full, we shut off the firehose
and go into a trickle mode to keep the pool fresh.  Saves CPU for everyone
and should make the contention drop off the charts too (though the trickle
factor might need adjusting again for Origin-class machines).

I was compiling for my plain 'ol PC, and was getting unresolved symbols
for get_memcfg_from_srat() and get_zholes_size().  The CONFIG_NUMA
definition right now allows it to be turned on for plain old X86_PC. 
Does anyone know why this is? 

depends on SMP && HIGHMEM64G &&
          (X86_PC || X86_NUMAQ || X86_GENERICARCH ||
                  (X86_SUMMIT && ACPI && !ACPI_HT_ONLY))

In any case, the summit code incorrectly assumes in at least 2 places
that NUMA && !NUMAQ means summit.  Someone was evidently trying to cover
the generic subarch case, but that's already taken care of by the lovely
config system and CONFIG_ACPI_SRAT.  This patch fixes those assumptions
and adds a nice little warning for people that try to #include srat.h
without having srat support turned on.

The mwave driver uses a user space daemon for some modem operations. The
user space daemon calls ioctl(,IOCTL_MW_GET_IPC), and the driver returns
after an interrupt arrived. The actual wait used
interruptible_sleep_on(), which can lead to lost wakeups. A local 
spinlock on the stack is used to close that race, but this is broken on 
SMP, perhaps even with preempt.

The attached patch fixes that by switching to the normal 
add_wait_queue/test_if_race_occured/schedule/remove_wait_queue sequence.

ext3 has fancy test harness code which allows you to simulate crashes (for
testing recovery).  It will make the underlying disk start ignoring writes a
specified number of seconds after the mount.

It's inoperative without an additional offline patch anyway, and it's doing
hacky things which scared Al.  So kill it; I'll maintain it in the separate
ext3 debug patch.

There is some inconsistency within lib/inflate.c and its users about
whether the error message text or the error() function should provide
the '\n'.

This patch tries to make everyone consistent - by removing the
newline from all message texts, and adding one to the only error()
function which did not provide it (in init/do_mounts_rd.c).

d_delete() calls dentry_iput() after releasing the per dentry lock.  This
can race with __d_lookup and lead to situation where we can make dentry

hold per dentry lock till d_inode is NULL and dentry has been removed from
d_alias list.

This patch against current bk makes the recently added SELinux boot
parameter feature a configurable option, and enables SELinux by default
when selected.  These changes were made following feedback including 
discussion on the SELinux list.

The rationale for the changes is to allow SELinux to be be configured and
enabled unconditionally.  If the boot parameter option is selected, then
SELinux is now enabled unless selinux=0 is specified at the kernel command
line.

Earlier patch wasn't correct especially in the !CONFIG_SCSI_IZIP_EPP16
case, reading all uses of this array (IMM_MODE_STRING is used to print the
corresponding string in printks).

If I'm not misunderstanding it, CONFIG_SCSI_IZIP_EPP16 means "use 16bit 
even when 32bit is requested".

It seems the right solution is

static char *IMM_MODE_STRING[] =
{
        [IMM_AUTODETECT] = "Autodetect",
        [IMM_NIBBLE]     = "SPP",
        [IMM_PS2]        = "PS/2",
        [IMM_EPP_8]      = "EPP 8 bit",
        [IMM_EPP_16]     = "EPP 16 bit",
#ifdef CONFIG_SCSI_IZIP_EPP16
        [IMM_EPP_32]     = "EPP 16 bit",
#else
        [IMM_EPP_32]     = "EPP 32 bit",
#endif
        [IMM_UNKNOWN]    = "Unknown",
};

The SuSE kernels place their ikconfig info at /proc/config.gz: in a
different place, and compressed.  We thought it was a good idea to do it
that way in 2.6 as well.

- gzip the /proc config file, put it in /proc/config.gz;

- Based on a SuSE patch by Oliver Xymoron <oxymoron@waste.org>, which was
  derived from a patch by Nicholas Leon <nicholas@binary9.net>

- change /proc/ikconfig/built_with to /proc/config_build_info;

- cleanup ikconfig init/exit entry points (static, __init, __exit);

- Makefile help from Sam Ravnborg;

ikconfig cleanup
EDESC
From: Stephen Hemminger <shemminger@osdl.org>

Simplify and cleanup the code:
	- use single interface to seq_file where possible
	- don't need to do as much of the /proc interface, only read
	- use copy_to_user to avoid char at a time copy
	- remove unneccesary globals
	- use const char[] rather than const char * where possible.

Didn't change the version since interface doesn't change.

This patch is forwarded from Jay Estabrook at HP.  I've compiled the
patch on ia32 and ia64 machines and it's good.  I also recreated
the patch so it would apply to mm5 without fuzzy offsets.
Here's Jay's summary of the patch:

Here's a very small set of patches against 2.6.0-test4 that help the
DAC960 driver compile cleaner (gets rid of warnings on Alpha) and help
it to work on some old OEM'ed DAC960 cards that were sold in our older
Alphas.

The warnings are all concerned with "conversions to different size
without cast", as pointers and longs are same size (8-bytes) but ints
are 4-bytes, on Alpha. I don't believe the change to (long) from (int)
will affect any 32-bit architectures, but those using LP64 like Alpha,
ie SPARC64 and prolly IA64, will have the warnings go away.

The change to make the oldest acceptable firmware version 2.70 instead
of 2.73 is made spcific to Alpha, since it is only those cards that
DEC OEM'ed from Mylex that would have such (as explained a bit better
in the patch itself).

From: Andrey Borzenkov <arvidjaar@mail.ru>

DAC960.c does it incorrectly (at least in 2.6.0-test4). It will create
_directory_ /dev/rd/cNdM making it impossible to create compat block device
entry with the same name.

The right thing it to create separate directory for each controller/target as 
in attached trivial patch (untested due to lack of hardware). You will need
devfsd support for this but then you will need it for cciss or cpqarray as 
well and possibly for others. Which returns us to the problem of devfsd 
maintenance ...

From: Dmitry Torokhov <dtor_core@ameritech.net>

I noticed that although timer_tsc registers cpufreq notifier to detect
frequency changes and adjust cpu_khz it does not set cyc2ns_scale.

From: Andrey Borzenkov <arvidjaar@mail.ru>

Various block drivers are currently devfs-unaware.  Andrey's patch attempts
to give them reasonable representations in devfs.


 "The attached patch suggests some possible names for non-floppy devices
  based on reading driver source.  I have to ask if these make sense.  At
  least for cciss Mandrake devfsd patch expects different names but it
  seems to be mistake (it assumes single controller always)

 "For floppy it is not as simple.  Floppy cannot use genhd and must
  create names manually; but I do not know what names are appropriate or
  expected.

 "For acsi the target/lun name may have problem of creating compat names
  (if any) by devfsd.

 "Please note that none of them created any devfs name under 2.4 as well.
   So it is not a regression ..."

CONFIG_TIMER_CYCLONE doesn't build at present because calibrate_tsc() was
