[PATCH] i386: Force data segment to be 4K aligned
o Currently there is no specific alignment restriction in linker script
and in some cases it can be placed non 4K aligned addresses. This fails
kexec which checks that segment to be loaded is page aligned.
o I guess, it does not harm data segment to be 4K aligned.

This patch fixes the problem, but only by introducing yet another parameter
to nfsd_create_v3. This is ugly. This will be fixed by later patches.

[PATCH] Regression in 2.6.19-rc microcode driver
If the microcode driver is built in (rather than module) there are some,
ehm, interesting effects happening due to the new "call out to userspace"
behavior that is introduced.. and which runs too early. The result is a
boot hang; which is really nasty.
The patch below is a minimally safe patch to fix this regression for 2.6.19
by just not requesting actual microcode updates during early boot. (That
is a good idea in general anyway)
The "real" fix is a lot more complex given the entire cpu hotplug scenario
(during cpu hotplug you normally need to load the microcode as well); but
the interactions for that are just really messy at this point; this fix at
least makes it work and avoids a full detangle of hotplug.

Since the "mask" bit is in the low word, when we write a new entry, we
need to write the high word first, before we potentially unmask it.
The exception is when we actually want to mask the interrupt, in which
case we want to write the low word first to make sure that the high word
doesn't change while the interrupt routing is still active.

[S390] revert add_active_range() usage patch.
Commit
7676bef9c183fd573822cac9992927ef596d584c breaks DCSS support on
s390. DCSS needs initialized struct pages to work. With the usage of
add_active_range() only the struct pages for physically present pages
are initialized.
This could be fixed if the DCSS driver would initiliaze the struct pages
itself, but this doesn't work too. This is because the mem_map array
does not include holes after the last present memory area and therefore
there is nothing that could be initialized.
To fix this and to avoid some dirty hacks revert this patch for now.
Will be added later when we move to a virtual mem_map.

[PATCH] sysctl: allow a zero ctl_name in the middle of a sysctl table
Since it is becoming clear that there are just enough users of the binary
sysctl interface that completely removing the binary interface from the kernel
will not be an option for foreseeable future, we need to find a way to address
the sysctl maintenance issues.
The basic problem is that sysctl requires one central authority to allocate
sysctl numbers, or else conflicts and ABI breakage occur. The proc interface
to sysctl does not have that problem, as names are not densely allocated.
By not terminating a sysctl table until I have neither a ctl_name nor a
procname, it becomes simple to add sysctl entries that don't show up in the
binary sysctl interface. Which allows people to avoid allocating a binary
sysctl value when not needed.
I have audited the kernel code and in my reading I have not found a single
sysctl table that wasn't terminated by a completely zero filled entry. So
this change in behavior should not affect anything.
I think this mechanism eases the pain enough that combined with a little
disciple we can solve the reoccurring sysctl ABI breakage.

The PHY clock is needed for some internal MAC blocks to function

tg3_setup_phy() can then be called later in the sequence without the

of sync with switch_user(), and accessing a user pointer that had been

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"

There's a possible race condition when doing a "switch_uid()" from one

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.

[PATCH] uml: include tidying
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.

[PATCH] uml: fix I/O hang
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.

[PATCH] reiserfs: reset errval after initializing bitmap cache
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().
