When I added the entries for the robust futex syscall entries, I
forgot to bump NR_SYSCALLS. The current situation is error-prone
because NR_SYSCALLS lives in entry.S where the system call limit
checks are enforced. Move the definition to asm/unistd.h in order to
make this mistake much more difficult to make.
And wire up sys_migrate_pages since the powerpc folks implemented the
compat wrapper for us.

It looks like I was stupid and made NetLabel depend on CONFIG_NET and not
CONFIG_INET, the patch below should fix this by making NetLabel depend on
CONFIG_INET and CONFIG_SECURITY. Please review and apply for 2.6.19.

It would be nice to keep things working even with this built as a
module, it took me some time to realize my IPv6 tunnel was broken
because of the missing sit module. This module alias fixes things

We have seen a couple of __alloc_pages() failures due to
fragmentation, there is plenty of free memory but no large order pages
available. I think the problem is in sock_alloc_send_pskb(), the
gfp_mask includes __GFP_REPEAT but its never used/passed to the page
allocator. Shouldnt the gfp_mask be passed to alloc_skb() ?

This fixes a bug reported in:
http://bugzilla.kernel.org/show_bug.cgi?id=7438
tg3_close() turns off the PHY if WoL and ASF are both disabled. On
the next tg3_open(), some devices such as the 5752M will not be
brought up correctly without a PHY reset early in the reset sequence.
The PHY clock is needed for some internal MAC blocks to function
correctly.
This problem is fixed by always resetting the PHY early in
tg3_reset_hw() when it is called from tg3_open() or tg3_resume().
tg3_setup_phy() can then be called later in the sequence without the
reset_phy parameter set to 1, since the PHY reset is already done.
Update version to 3.68.

Calculation of IPX checksum got buggered about 2.4.0. The old variant
mangled the packet; that got fixed, but calculation itself got buggered.
Restored the correct logics, fixed a subtle breakage we used to have even
back then: if the sum is 0 mod 0xffff, we want to return 0, not 0xffff.
The latter has special meaning for IPX (cheksum disabled). Observation
(and obvious fix) nicked from history of FreeBSD ipx_cksum.c...

The previous commit (45c18b0bb579b5c1b89f8c99f1b6ffa4c586ba08, aka "Fix
unlikely (but possible) race condition on task->user access") fixed a
potential oops due to __sigqueue_alloc() getting its "user" pointer out
of sync with switch_user(), and accessing a user pointer that had been
de-allocated on another CPU.
It still left another (much less serious) problem, where a concurrent
__sigqueue_alloc and swich_user could cause sigqueue_alloc to do signal
pending reference counting for a _different_ user than the one it then
actually ended up using. No oops, but we'd end up with the wrong signal
accounting.
Another case of Oleg's eagle-eyes picking up the problem.
This is trivially fixed by just making sure we load whichever "user"
structure we decide to use (it doesn't matter _which_ one we pick, we
just need to pick one) just once.

There's a possible race condition when doing a "switch_uid()" from one
user to another, which could race with another thread doing a signal
allocation and looking at the old thread ->user pointer as it is freed.
This explains an oops reported by Lukasz Trabinski:
http://permalink.gmane.org/gmane.linux.kernel/462241
We fix this by delaying the (reference-counted) freeing of the user
structure until the thread signal handler lock has been released, so
that we know that the signal allocation has either seen the new value or
has properly incremented the reference count of the old one.
Race identified by Oleg Nesterov.

Commit 5a06a363ef48444186f18095ae1b932dddbbfa89 ("[PATCH] ipc/msg.c:
clean up coding style") breaks fakeroot on Alpha (variously hangs or
oopses), according to a report by Falk Hueffner.
The fact that the code seems to rely on compiler access ordering through
the use of "volatile" is a pretty certain sign that the code has locking
problems, and we should fix those properly and then remove the whole
"volatile" entirely.
But in the meantime, the movement of "volatile" was unintentional, and
should be reverted.

The user.* extended attributes are only allowed on regular files and
directories. Sticky directories further restrict write access to the owner
and privileged users. (See the attr(5) man page for an explanation.)
The original check in ext2/ext3 when user.* xattrs were merged was more
restrictive than intended, and when the xattr permission checks were moved
into the VFS, read access to user.* attributes on sticky directores ended
up being denied in addition.

sys_move_pages() uses vmalloc() to allocate an array of structures that is
fills with information passed from user mode and then passes to
do_stat_pages() (in the case the node list is NULL). do_stat_pages()
depends on a marker in the node field of the structure to decide how large
the array is and this marker is correctly inserted into the last element of
the array. However, vmalloc() doesn't zero the memory it allocates and if
the user passes NULL for the node list, then the node fields are not filled
in (except for the end marker). If the memory the vmalloc() returned
happend to have a word with the marker value in it in just the right place,
do_pages_stat will fail to fill the status field of part of the array and
we will return (random) kernel data to user mode.

In order to get the __NR_* constants, we need sys/syscall.h.
linux/unistd.h works as well since it includes syscall.h, however syscall.h
is more parsimonious. We were inconsistent in this, and this patch adds
syscall.h includes where necessary and removes linux/unistd.h includes
where they are not needed.
asm/unistd.h also includes the __NR_* constants, but these are not the
glibc-sanctioned ones, so this also removes one such inclusion.

Fix a UML hang in which everything would just stop until some I/O happened
- a ping, someone whacking the keyboard - at which point everything would
start up again as though nothing had happened.
The cause was gcc reordering some code which absolutely needed to be
executed in the order in the source. When unblock_signals switches signals
from off to on, it needs to see if any interrupts had happened in the
critical section. The interrupt handlers check signals_enabled - if it is
zero, then the handler adds a bit to the "pending" bitmask and returns.
unblock_signals checks this mask to see if any signals need to be
delivered.
The crucial part is this:
signals_enabled = 1;
save_pending = pending;
if(save_pending == 0)
return;
pending = 0;
In order to avoid an interrupt arriving between reading pending and setting
it to zero, in which case, the record of the interrupt would be erased,
signals are enabled.
What happened was that gcc reordered this so that 'save_pending = pending'
came before 'signals_enabled = 1', creating a one-instruction window within
which an interrupt could arrive, set its bit in pending, and have it be
immediately erased.
When the I/O workload is purely disk-based, the loss of a block device
interrupt stops the entire I/O system because the next block request will
wait for the current one to finish. Thus the system hangs until something
else causes some I/O to arrive, such as a network packet or console input.
The fix to this particular problem is a memory barrier between enabling
signals and reading the pending signal mask. An xchg would also probably
work.
Looking over this code for similar problems led me to do a few more
things:
- make signals_enabled and pending volatile so that they don't get cached
in registers
- add an mb() to the return paths of block_signals and unblock_signals so
that the modification of signals_enabled doesn't get shuffled into the
caller in the event that these are inlined in the future.

Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL
until much later. If a condition fails before errval is reset later,
reiserfs_fill_super() will mistakenly return 0, causing an Oops in
do_add_mount(). This patch resets errval to -EINVAL after the call.
I view this as a temporary fix and real error codes should be used
throughout reiserfs_fill_super().

Add a swsusp debugging mode. This does everything that's needed for a suspend
except for actually suspending. So we can look in the log messages and work
out a) what code is being slow and b) which drivers are misbehaving.
(1)
# echo testproc > /sys/power/disk
# echo disk > /sys/power/state
This should turn off the non-boot CPU, freeze all processes, wait for 5
seconds and then thaw the processes and the CPU.
(2)
# echo test > /sys/power/disk
# echo disk > /sys/power/state
This should turn off the non-boot CPU, freeze all processes, shrink
memory, suspend all devices, wait for 5 seconds, resume the devices etc.

{
int status;
/* For now this directory should already be empty, but we empty it of
* any regular files anyway, just in case the directory was created by
* a kernel from the future.... */
nfsd4_list_rec_dir(dentry, nfsd4_remove_clid_file);
mutex_lock(&dir->d_inode->i_mutex);
status = vfs_rmdir(dir->d_inode, dentry);
...
int vfs_rmdir(struct inode *dir, struct dentry *dentry)
{
int error = may_delete(dir, dentry, 1);
if (error)
return error;
if (!dir->i_op || !dir->i_op->rmdir)
return -EPERM;
DQUOT_INIT(dir);
mutex_lock(&dentry->d_inode->i_mutex);
...
So I have developed the patch to overcome this problem.

pages_list. So, readpages() just can ignore the remaining pages in
pages_list.

Fix module_param/sysfs file permission typo.
Clean up MODULE_PARM_DESC strings to avoid fancy (and incorrect)
formatting.
Fix header includes for lkdtm; add some needed ones, remove unused ones;
and fix this gcc warning:
drivers/misc/lkdtm.c:150: warning: 'struct buffer_head' declared inside parameter list
drivers/misc/lkdtm.c:150: warning: its scope is only this definition or declaration, which is probably not what you want

ufs2 fails to mount on x86_64, claiming bad magic. This is because
ufs_super_block_third's fs_un1 member is padded out by 4 bytes for 8-byte
alignment, pushing down the rest of the struct.
Forcing this to be packed solves it. I took a quick look over other
on-disk structures and didn't immediately find other problems. I was able
to mount & ls a populated ufs2 filesystem w/ this change.

Fix two issuses related to ipc_ids->entries freeing.
1. When freeing ipc namespace we need to free entries allocated
with ipc_init_ids().
2. When removing old entries in grow_ary() ipc_rcu_putref()
may be called on entries set to &ids->nullentry earlier in
ipc_init_ids().
This is almost impossible without namespaces, but with
them this situation becomes possible.
Found during OpenVZ testing after obvious leaks in beancounters.
