This changes hvc_init() to be called only when someone actually uses the
hvc_console driver. Dave Jones complained when profiling bootup.hvc_console used to only be for Power aka pSeries: now lguest and Xen both
want it built-in in case the kernel is a guest under one of those, even
though usually it will be a native boot.Signed-off-by: Rusty Russell

include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO. fs/binfmt_elf.c
has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT
entries. So in the worst case, saved_auxv does not get an AT_NULL entry at
the end.The saved_auxv array must be terminated with an AT_NULL entry. Make the
size of mm_struct->saved_auxv arch dependend, based on the number of

This patch does additional coding style fixup. Initially the code is being
distorted by Lindent (in my patches sent not very long ago) and fixed in
the followup patches but this stuff was accidently missed.New and old compiled files were compared with cmp to check for being
identically. So the patch will not break the kernel.Signed-off-by: Cyrill Gorcunov

This adds three new functions (or in one case to be more exact makes it
always available)tty_termios_copy_hw
Copies all the hardware settings from one termios structure to the other.
This is intended for drivers that support little or no hardware settingtty_termios_encode_baud_rate
Allows you to set the input and output baud rate in a termios structure. A
driver is supposed to set the resulting baud rate from a request so most
will want to use this function to set the resulting input and output rates
to match the hardware values. Internally it knows about keeping Bxxx
encoding when possible to maximise compatibility.tty_encode_baud_rate
As above but for the tty's own current termios structure
I suspect this will initially need some tweaking as it gets enabled by
driver patches over the next few mm cycles so consider this lot -mm only
for the moment so it can stabilize and end up neat before it goes to base.I've tried not to break any obscure architectures - if you get a speed you
can't represent the code will print warnings on non updated termios systems
but not break.Once this is merged and seems sane I've got a growing pile of driver
updates to use it - notably for USB serial drivers.[akpm@linux-foundation.org: cleanups]

There is possible dead loop in finish_unfinished function.
In most situation, the call chain iput -> ... -> reiserfs_delete_inode ->
remove_save_link will success. But for some reason such as data
corruption, reiserfs_delete_inode fails on reiserfs_do_truncate ->
search_for_position_by_key.Then remove_save_link won't be called. We always get the same
"save_link_key" in the while loop in finish_unfinished function. The
following patch adds a check for the possible dead loop and just remove
save link when deap loop.[akpm@linux-foundation.org: cleanups]

This patch makes shrink_dcache_sb consistent with dentry pruning policy.
On the first pass we iterate over dentry unused list and prepare some
dentries for removal.However, since the existing code moves evicted dentries to the beginning of
the LRU it can happen that fresh dentries from other superblocks will be
inserted *before* our dentries.This can result in significant slowdown of shrink_dcache_sb(). Moreover,
for virtual filesystems like unionfs which can call dput() during dentries
kill existing code results in O(n^2) complexity.We observed 2 minutes shrink_dcache_sb() with only 35000 dentries.
To avoid this effects we propose to isolate sb dentries at the end
of LRU list.Signed-off-by: Denis V. Lunev

Remove the old-fashioned lk201 driver under drivers/tc/ that used to be
used by the old dz.c and zs.c drivers, which is now orphan code referred to
from nowhere and does not build anymore. A modern replacement is available
as drivers/input/keyboard/lkkbd.c.There are no plans to do anything about this piece of code and it does not
fit anywhere anymore, so it is not just a matter of maintenance or the lack
of. There are still some bits that might be added to the new lkkbd.c
driver based on the old code, and the embedded hardware documentation which
is otherwise quite hard to get hold of might be useful to keep too. Both
of these can be done separately though. RIP.Signed-off-by: Maciej W. Rozycki

Make request_key() and co fundamentally asynchronous to make it easier for
NFS to make use of them. There are now accessor functions that do
asynchronous constructions, a wait function to wait for construction to
complete, and a completion function for the key type to indicate completion
of construction.Note that the construction queue is now gone. Instead, keys under
construction are linked in to the appropriate keyring in advance, and that
anyone encountering one must wait for it to be complete before they can use
it. This is done automatically for userspace.The following auxiliary changes are also made:
(1) Key type implementation stuff is split from linux/key.h into
linux/key-type.h.(2) AF_RXRPC provides a way to allocate null rxrpc-type keys so that AFS does
not need to call key_instantiate_and_link() directly.(3) Adjust the debugging macros so that they're -Wformat checked even if
they are disabled, and make it so they can be enabled simply by defining
__KDEBUG to be consistent with other code of mine.(3) Documentation.

reiserfs_invalidatepage will refuse to free pages if they have been logged
in data=journal mode, or were pinned down by a data=ordered operation. For
data=journal, this is fairly easy to trigger just with fsx-linux, and it
results in a large number of pages hanging around on the LRUs with
page->mapping == NULL.Calling try_to_free_buffers when reiserfs decides it is done with the page
allows it to be freed earlier, and with much less VM thrashing. Lock
ordering rules mean that reiserfs can't call lock_page when it is releasing
the buffers, so TestSetPageLocked is used instead. Contention on these
pages should be rare, so it should be sufficient most of the time.Signed-off-by: Chris Mason

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes. Originally it was basically the raw
MIPS low level cache API exported to the entire world. The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync. So
remove it rsp. turn the surviving bits back into an arch private API, as
discussed on linux-arch.Signed-off-by: Ralf Baechle

Negative shifts are not allowed in C (the result is undefined). Same thing
with full-width shifts.It works on most platforms but not on the VAX with gcc 4.0.1 (it results in an
"operand reserved" fault).Shifting by more than the width of the value on the left is also not
allowed. I think the extra '>> 1' tacked on at the end in the original
code was an attempt to work around that. Getting rid of that is an extra
feature of this patch.Here's the chapter and verse, taken from the final draft of the C99
standard ("6.5.7 Bitwise shift operators", paragraph 3):"The integer promotions are performed on each of the operands. The
type of the result is that of the promoted left operand. If the
value of the right operand is negative or is greater than or equal
to the width of the promoted left operand, the behavior is
undefined."Thank you to Jan-Benedict Glaw, Christoph Hellwig, Maciej Rozycki, Pekka
Enberg, Andreas Schwab, and Christoph Lameter for review. Special thanks
to Andreas for spotting that my fix only removed half the undefined
behaviour.Signed-off-by: Peter Lund

Various architectures may call bust_spinlocks() recursively; the function
itself, however, doesn't appear to be meant to be called in this manner.
Nevertheless, this doesn't appear to be a problem as long as
bust_spinlocks(0) doesn't get called twice in a row (otherwise,
unblank_screen() may enter the scheduler). However, at least on i386 die()
has been capable of returning (and on other architectures this should
really be that way, too) when notify_die() returns NOTIFY_STOP.Short of getting a reply to a respective query, this patch makes
bust_spinlocks() increment/decrement oops_in_progress, and wake klogd only
when the count drops back to zero.Signed-off-by: Jan Beulich
