[SPARC64]: Fix boot failures on SunBlade-150
The sequence to move over to the Linux trap tables from
the firmware ones needs to be more air tight. It turns
out that to be %100 safe we do need to be able to translate
OBP mappings in our TLB miss handlers early.
In order not to eat up a lot of kernel image memory with
static page tables, just use the translations array in
the OBP TLB miss handlers. That solves the bulk of the
problem.
Furthermore, to make sure the OBP TLB miss path will work
even before the fixed MMU globals are loaded, explicitly
load %g1 to TLB_SFSR at the beginning of the i-TLB and
d-TLB miss handlers.
To ease the OBP TLB miss walking of the prom_trans[] array,
we sort it then delete all of the non-OBP entries in there
(for example, there are entries for the kernel image itself
which we're not interested in at all).
We also save about 32K of kernel image size with this change.
Not a bad side effect :-)
There are still some reasons why trampoline.S can't use the
setup_trap_table() yet. The most noteworthy are:
1) OBP boots secondary processors with non-bias'd stack for
some reason. This is easily fixed by using a small bootup
stack in the kernel image explicitly for this purpose.
2) Doing a firmware call via the normal C call prom_set_trap_table()
goes through the whole OBP enter/exit sequence that saves and
restores OBP and Linux kernel state in the MMUs. This path
unfortunately does a "flush %g6" while loading up the OBP locked
TLB entries for the firmware call.
If we setup the %g6 in the trampoline.S code properly, that
is in the PAGE_OFFSET linear mapping, but we're not on the
kernel trap table yet so those addresses won't translate properly.
One idea is to do a by-hand firmware call like we do in the
early bootup code and elsewhere here in trampoline.S But this
fails as well, as aparently the secondary processors are not
booted with OBP's special locked TLB entries loaded. These
are necessary for the firwmare to processes TLB misses correctly
up until the point where we take over the trap table.
This does need to be resolved at some point.

[ARM] 2974/1: fix ARM710 swi bug workaround
Patch from Nicolas Pitre
Either no one is using an ARM710 with recent kernels, or all ARM710s
still in use are not afflicted by this swi bug. Nevertheless, the code
to work around the ARM710 swi bug is itself currently buggy since it
uses r8 as a pointer to S_PC while in fact it holds the spsr content
these days. Fix that, and simplify the code as well.

[PATCH] ppc32: Tell userland about lack of standard TB
Glibc is about to get some new high precision timer stuff that relies on
the standard timebase of the PPC architecture.
However, some (rare & old) CPUs do not have such timebase and it is a
bit annoying to have your stuff just crash because you are running on
the wrong CPU...
This exposes to userland a CPU feature bit that tells that the current
processor doesn't have a standard timebase. It's negative logic so that
glibc will still "just work" on older kernels (it will just be unhappy
on those old CPUs but that doesn't really matter as distro tend to
update glibc & kernel at the same time).

[PATCH] ppc32: Fix timekeeping
Interestingly enough, ppc32 had broken timekeeping for ages... It
worked, but probably drifted a bit more than could be explained by the
actual bad precision of the timebase calibration. We discovered that
recently when somebody figured out that the common code was using
CLOCK_TICK_RATE to correct the timekeeing, and ppc32 had a completely
bogus value for it.
This patch turns it into something saner. Probably not as good as doing
something based on the actual timebase frequency precision but I'll
leave that sort of math to others. This at least makes it better for

[PATCH] nfsacl: Solaris VxFS compatibility fix
Here is a compatibility fix between Linux and Solaris when used with VxFS

VxFS it replies with NFSERR_INVAL when it sees a four-entry acl that is not
in canonical form. It may also fail with other non-canonical acls -- I
can't tell, because that case never triggers: We only send non-canonical
acls when we fake up an ACL_MASK entry.
Instead of adding fake ACL_MASK entries at the end, inserting them in the
correct position makes Solaris+VxFS happy. The Linux client and server
sides don't care about entry order. The three-entry-acl special case in

[PATCH] dell_rbu: changes in packet update mechanism
In the current dell_rbu code ver 2.0 the packet update mechanism makes the
user app dump every individual packet in to the driver.
This adds in efficiency as every packet update makes the
/sys/class/firmware/dell_rbu/loading and data files to disappear and reappear
again. Thus the user app needs to wait for the files to reappear to dump
another packet. This slows down the packet update tremendously in case of
large number of packets. I am submitting a new patch for dell_rbu which will
change the way we do packet updates;
In the new method the user app will create a new single file which has already
packetized the rbu image and all the packets are now staged in this file.
This driver also creates a new entry in
/sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet
size here before downloading the packet file.
The user should do the following:
create one single file which has all the packets stacked together.
echo the packet size in to /sys/devices/platform/dell_rbu/packet_size.
echo 1 > /sys/class/firmware/dell_rbu/loading
cat the packetfile > /sys/class/firmware/dell_rbu/data
echo 0 > /sys/class/firmware/dell_rbu/loading
The driver takes the file which came through /sys/class/firmware/dell_rbu/data
and takes chunks of paket_size data from it and place in contiguous memory.
This makes packet update process very efficient and fast. As all the packet
update happens in one single operation. The user can still read back the
downloaded file from /sys/devices/platform/dell_rbu/data.

This patch fixes the following bugs in ESP:
* Fix transport mode MTU overestimate. This means that the inner MTU

For example, given a standard ESP/3DES/MD5 transform and an MTU of

The reason for this is because IP header lengths are always a multiple

Use the new "kill_proc_info_as_uid()" for USB disconnect too
All the same issues - we can't just save the pointer to the thread, we
must save the pid/uid/euid combination.

[PATCH] Fix signal sending in usbdevio on async URB completion
If a process issues an URB from userspace and (starts to) terminate
before the URB comes back, we run into the issue described above. This
is because the urb saves a pointer to "current" when it is posted to the
device, but there's no guarantee that this pointer is still valid
afterwards.
In fact, there are three separate issues:
1) the pointer to "current" can become invalid, since the task could be
completely gone when the URB completion comes back from the device.
2) Even if the saved task pointer is still pointing to a valid task_struct,
task_struct->sighand could have gone meanwhile.
3) Even if the process is perfectly fine, permissions may have changed,
and we can no longer send it a signal.
So what we do instead, is to save the PID and uid's of the process, and
introduce a new kill_proc_info_as_uid() function.

[SPARC64]: Fix Ultra5, Ultra60, et al. boot failures.
On the boot processor, we need to do the move onto the Linux trap
table a little bit differently else we'll take unhandlable faults in
the firmware address space.
Previously we would do the following:
1) Disable PSTATE_IE in %pstate.
2) Set %tba by hand to sparc64_ttable_tl0
3) Initialize alternate, mmu, and interrupt global
trap registers.
4) Call prom_set_traptable()
That doesn't work very well actually with the way we boot the kernel
VM these days. It worked by luck on many systems because the firmware
accesses for the prom_set_traptable() call happened to be loaded into
the TLB already, something we cannot assume.
So the new scheme is this:
1) Clear PSTATE_IE in %pstate and set %pil to 15
2) Call prom_set_traptable()
3) Initialize alternate, mmu, and interrupt global
trap registers.
and this works quite well. This sequence has been moved into a
callable function in assembler named setup-trap_table(). The idea is
that eventually trampoline.S can use this code as well. That isn't
possible currently due to some complications, but eventually we should
be able to do it.
Thanks to Meelis Roos for the Ultra5 boot failure report.

[PATCH] x86_64: Fix change_page_attr cache flushing
Noticed by Terence Ripperda
Undo wrong change in global_flush_tlb. We need to flush the caches in all
cases, not just when pages were reverted. This was a bogus optimization
added earlier, but it was wrong.
