[PATCH] powerpc: Make rtas console _much_ faster
Currently the hvc_rtas driver is painfully slow to use. Our "benchmark" is
ls -R /etc, which spits out about 27866 characters. The theoretical maximum
speed would be about 2.2 seconds, the current code takes ~50 seconds.
The core of the problem is that sometimes when the tty layer asks us to push
characters the firmware isn't able to handle some or all of them, and so
returns an error. The current code sees this and just returns to the tty code
with the buffer half sent.
The khvcd thread will eventually wake up and try to push more characters, which
will usually work because by then the firmware's had time to make room. But
the khvcd thread only wakes up every 10 milliseconds, which isn't fast enough.
So change the khvcd thread logic so that if there's an incomplete write we
yield() and then immediately try writing again. Doing so makes POLL_QUICK and
POLL_WRITE synonymous, so remove POLL_QUICK.
With this patch our "benchmark" takes ~2.8 seconds.

[PATCH] powerpc: Implement support for setting little-endian mode via prctl
This adds the PowerPC part of the code to allow processes to change
their endian mode via prctl.
This also extends the alignment exception handler to be able to fix up
alignment exceptions that occur in little-endian mode, both for
"PowerPC" little-endian and true little-endian.
We always enter signal handlers in big-endian mode -- the support for
little-endian mode does not amount to the creation of a little-endian
user/kernel ABI. If the signal handler returns, the endian mode is
restored to what it was when the signal was delivered.
We have two new kernel CPU feature bits, one for PPC little-endian and
one for true little-endian. Most of the classic 32-bit processors
support PPC little-endian, and this is reflected in the CPU feature
table. There are two corresponding feature bits reported to userland
in the AT_HWCAP aux vector entry.
This is based on an earlier patch by Anton Blanchard.

[PATCH] Add a prctl to change the endianness of a process.
This new prctl is intended for changing the execution mode of the
processor, on processors that support both a little-endian mode and a
big-endian mode. It is intended for use by programs such as
instruction set emulators (for example an x86 emulator on PowerPC),
which may find it convenient to use the processor in an alternate
endianness mode when executing translated instructions.
Note that this does not imply the existence of a fully-fledged ABI for
both endiannesses, or of compatibility code for converting system
calls done in the non-native endianness mode. The program is expected
to arrange for all of its system call arguments to be presented in the
native endianness.
Switching between big and little-endian mode will require some care in
constructing the instruction sequence for the switch. Generally the
instructions up to the instruction that invokes the prctl system call
will have to be in the old endianness, and subsequent instructions
will have to be in the new endianness.

[PATCH] powerpc: Fix buglet with MMU hash management
Our MMU hash management code would not set the "C" bit (changed bit) in
the hardware PTE when updating a RO PTE into a RW PTE. That would cause
the hardware to possibly to a write back to the hash table to set it on
the first store access, which in addition to being a performance issue,
might also hit a bug when running with native hash management (non-HV)
as our code is specifically optimized for the case where no write back
happens.
Thus there is a very small therocial window were a hash PTE can become
corrupted if that HPTE has just been upgraded to read write, a store
access happens on it, and that races with another processor evicting
that same slot. Since eviction (caused by an almost full hash) is
extremely rare, the bug is very unlikely to happen fortunately.
This fixes by allowing the updating of the protection bits in the native
hash handling to also set (but not clear) the "C" bit, and, in order to
also improve performances in the general case, by always setting that
bit on newly inserted hash PTE so that writeback really never happens.

call, and uses that. A better fix for later is to arrange for the event to

Note: avoiding the sysfs call isn't a problem as an error will not, by

[PATCH] powerpc: Fix boot on eMac
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Prevent calling of some platform functions on the clock chips of the eMac
as it seems to cause it to lockup at boot. For now, add a quirk to prevent
that from happening. Later, I might find out what's wrong and fix it but
that doesn't seem to be important as the machine appear to work fine
without running those. It's possible that Darwin doesn't run them.

[PATCH] IPMI: reserve I/O ports separately
From: Corey Minyard <minyard@acm.org>
This patch is pretty important to get in for IPMI, new systems have been
changing the way ACPI and IPMI interact, and this works around the problems
for now. This is a temporary fix until we get proper ACPI handling in
IPMI.
Fixed releasing already-allocated regions when a later request fails, and
forward-ported it to HEAD.
Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI
controller. This causes problems when trying to register the entire I/O
region. Therefore we must register each I/O port separately.

[PATCH] tpm: more bios log parsing fixes
From: Seiji Munetoh <seiji.munetoh@gmail.com>
Change the binary output format to actual ACPI TCPA log structure since the
current format does not contain all event-data information that need to
verify the PCRs in TPM. tpm_binary_bios_measurements_show() uses
get_event_name() to convert the binary event-data to ascii format, and puts
them as binary. However, to verify the PCRs, the event-data must be a
actual binary event-data used by SHA1 calc. in BIOS.
So, I think actual ACPI TCPA log is good for this binary output format.
That way, any userland tools easily parse this data with reference to TCG
PC specification.

Actually, we just stumbled on a different bug found in find_e820_area() in

while (bad_addr(&addr, size) && addr+size < ei->addr + ei->size)
;
last = addr + size;
if ( last > ei->addr + ei->size )
continue;
The second statement in the while loop needs to be a <= b so that it is the
logical negavite of the if (a > b) outside it. It needs to read:
while (bad_addr(&addr, size) && addr+size <= ei->addr + ei->size)
;
In the case that failed bad_addr was returning an address that is exactly size
bellow the end of the e820 range.

[PATCH] s390: qeth driver fixes
From: Frank Blaschka <Frank.Blaschka@de.ibm.com>
From: Frank Pavlic <fpavlic@de.ibm.com>
- fix fake_ll during initial device bringup. fake_ll was
not active after first start of the device.
Problem only occured when qeth was built without IPV6 support.
- avoid skb usage after invocation of qeth_flush_buffers,
because skb might already be freed.
- remove yet another useless netif_wake_queue in
qeth_softsetup_ipv6 since this function is only called
when device is going online. In this case card->state will
never be in state UP. So let the net_device queue down .

- correct checking of sscanf-%n value in qeth_string_to_ipaddr().
- don't use netif_stop_queue outside the hard_start_xmit routine.
Rather use netif_tx_disable.
- don't call qeth_netdev_init on a recovery.

[PATCH] pcnet32: remove incorrect pcnet32_free_ring
During a code scan for another change I discovered that this call to
pcnet32_free_ring must be removed. If the open fails due to a lack of
memory all the ring structures are removed via the call to free_ring
and a subsequent call to open will dereference a null pointer in
pcnet32_init_ring.
Please apply to 2.6.17.

e1000: add shutdown handler back to fix WOL
Someone was waaay too aggressive and removed e1000's reboot notifier
instead of porting it to the new way of the shutdown handler. This change
broke wake on lan. Add the shutdown handler back in using the same method
as e100 uses.

The TPM chip on the ThinkPad T60 and Z60 machines is returning 0xFFFF for
the vendor ID which is a check the driver made to double check it was
actually talking to the memory mapped space of a TPM. This patch removes
the check since it isn't absolutely necessary and was causing device
discovery to fail on these machines.
