These have been broken (returning "int") since the dawn of

424acaaeb3
rwsem: wake queued readers when writer blocks on active read lock
made this change:
- (rwsem_atomic_update(0, sem) & RWSEM_ACTIVE_MASK))
- /* Someone grabbed the sem already */
+ rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS)
+ /* Someone grabbed the sem for write already */
RWSEM_ACTIVE_MASK is 0xffffffffL, so the old code only looked
at the low order 32-bits. The new code needs to see all 64 bits.

Until now, the tile architecture ABI for syscall return has just been
that r0 holds the return value, and an error is only signalled like it is
for kernel code, with a negative small number.
However, this means that in multiple places in userspace we end up writing
the same three-cycle idiom that tests for a small negative number for
error. It seems cleaner to instead move that code into the kernel, and
set r1 to hold zero on success or errno on failure; previously, r1 was
just zeroed on return from the kernel (to avoid leaking kernel state).
This way a single conditional branch after the syscall is sufficient
to test for the failure case. The number of cycles taken is the same,
but the error-checking code is in just one place, so total code size is
smaller, and random userspace syscall code is easier to understand.

It's wrong for several reasons, but the most direct one is that the
fault may be for the stack accesses to set up a previous SIGBUS. When
we have a kernel exception, the kernel exception handler does all the
fixups, not some user-level signal handler.
Even apart from the nested SIGBUS issue, it's also wrong to give out
kernel fault addresses in the signal handler info block, or to send a
SIGBUS when a system call already returns EFAULT.

First, the siginfo preamble wasn't quite right; we need to indicate
that we are padding up to 4 ints of preamble for 64-bit code, and
then for compat mode we need to pad differently, using only 3 ints.
Second, the C ABI requires a save area of two registers, not two
pointers, since in compat mode we have 64-bit registers all of which
we need to save, even though we only have 32-bit VAs.

We were using the same 5-sec minsec for the clocksource and sched_clock
that we were using for the clock_event_device. For the clock_event_device
that's exactly right since it has a short maximum countdown time.
But for sched_clock we want to avoid wraparound when converting from
ticks to nsec over a much longer window, so we force a shift of 10.
And for clocksource it seems dodgy to use a 5-sec minsec as well, so we
copy some other platforms and force a shift of 22.

To keep panic_timeout accuracy when running under a hypervisor, the

That brings a good effect, but the problem is the keyboard LEDs don't

This patch changes to call to panic_blink_enter() between every mdelay and
keeps blinking in spite of long spin timer mode.

Architectures implement dma_is_consistent() in different ways (some
misinterpret the definition of API in DMA-API.txt). So it hasn't been so
useful for drivers. We have only one user of the API in tree. Unlikely
out-of-tree drivers use the API.
Even if we fix dma_is_consistent() in some architectures, it doesn't look
useful at all. It was invented long ago for some old systems that can't
allocate coherent memory at all. It's better to export only APIs that are
definitely necessary for drivers.

Subject: [PATCH 12/19] ARM: cam60: don't use __init for cam60_spi_{flash_platform_data,partitions}
Date: Thu, 5 Aug 2010 16:08:46 +0200
Message-Id: <1281017333-5563-12-git-send-email-u.kleine-koenig@pengutronix.de>
These two structs are referenced by cam60_spi_devices. The latter is
copied at init time to kmalloced memory and so the copy isn't freed after
booting. So it must not contain references to .init memory.
This isn't noticed by modpost as cam60_spi_devices is in .init.data, too.

cam60_spi_devices is passed to at91_add_device_spi which calls
spi_register_board_info. The latter makes a copy of it, so living in
.init.data is OK.
This fixes the following warning in cam60_defconfig:
WARNING: vmlinux.o(.data+0x2a00): Section mismatch in reference from the variable cam60_spi_devices to the (unknown reference) .init.data:(unknown)
The variable cam60_spi_devices references

Add support for the dedicated FIFO mode on newer SoCs such as the S5PV210
partly to improve support and to fix the bug where any non-EP0 IN endpoint
requires its own FIFO allocation.
To fix this, we ensure that any non-zero IN endpoint is given a TXFIFO
using the same allocation method as the periodic case (all our current
hardware has enough FIFOs and FIFO memory for a 1:1 mapping) and ensure
that the necessary transmission done interrupt is enabled.
The default settings from reset for the core point all EPs at FIFO0,
used for the control endpoint. However, the controller documentation
states that all IN endpoints _must_ have a unique FIFO to avoid any
contention during transmission.
Note, this leaves us with a large IN FIFO for EP0 (which re-uses the
old NPTXFIFO) for an endpoint which cannot shift more than a pair of
packets at a time... this is a waste, but it looks like we cannot
re-allocate space to the individual IN FIFOs as they are already
maxed out (to be confirmed).

This fixes a regression due to the new apb_pclk stuff in the U300
platform, makes it run by splitting the apb clock off the single
UART clocks. For the MMCI and PL022 clocks we don't split them:
these are actually hardwired to the same clock terminal and will
thus simply have a double reference count and will be referenced
twice.
We also move clock registration to .init_irq() so they are
available early enough for probing to be successful and remove the
earlier quirk to clock primecells during PrimeCell registration.

On versions of the Cortex-A9 prior to r2p0, performing TLB invalidations by
ASID match can result in the incorrect ASID being broadcast to other CPUs.
As a consequence of this, the targetted TLB entries are not invalidated
across the system.
This workaround changes the TLB flushing routines to invalidate entries
regardless of the ASID.

This patch is against the 2.6.34 source.
Paraphrased from the 1989 BSD patch by David Borman @ cray.com:
These are the changes needed for the kernel to support
LINEMODE in the server.
There is a new bit in the termios local flag word, EXTPROC.
When this bit is set, several aspects of the terminal driver
are disabled. Input line editing, character echo, and mapping
of signals are all disabled. This allows the telnetd to turn
off these functions when in linemode, but still keep track of
what state the user wants the terminal to be in.
New ioctl:
TIOCSIG Generate a signal to processes in the
current process group of the pty.
There is a new mode for packet driver, the TIOCPKT_IOCTL bit.
When packet mode is turned on in the pty, and the EXTPROC bit
is set, then whenever the state of the pty is changed, the
next read on the master side of the pty will have the TIOCPKT_IOCTL
bit set. This allows the process on the server side of the pty
to know when the state of the terminal has changed; it can then
issue the appropriate ioctl to retrieve the new state.
Since the original BSD patches accompanied the source code for telnet
I've left that reference here, but obviously the feature is useful for
any remote terminal protocol, including ssh.
The corresponding feature has existed in the BSD tty driver since 1989.
For historical reference, a good copy of the relevant files can be found
here:

The following patches implement hardware performance events for the Alpha
EV67 and later CPUs. I have had this running on a Compaq XP1000 (EV67,
single CPU) for a few days now. Pretty cool -- discovered that the glibc
exp2() library routine uses on average 985 cycles to execute 777 CPU
instructions whereas Compaq's CPML library version of exp2() uses on
average 32 cycles to execute 47 CPU instructions to achieve the same
thing!
This patch:
Add performance monitor interrupt counternd and export the count to user
space via /proc/interrupts.

kunmap_atomic() is currently at level -4 on Rusty's "Hard To Misuse"
list[1] ("Follow common convention and you'll get it wrong"), except in
some architectures when CONFIG_DEBUG_HIGHMEM is set[2][3].
kunmap() takes a pointer to a struct page; kunmap_atomic(), however, takes
takes a pointer to within the page itself. This seems to once in a while
trip people up (the convention they are following is the one from
kunmap()).
Make it much harder to misuse, by moving it to level 9 on Rusty's list[4]
("The compiler/linker won't let you get it wrong"). This is done by
refusing to build if the type of its first argument is a pointer to a
struct page.
The real kunmap_atomic() is renamed to kunmap_atomic_notypecheck()
(which is what you would call in case for some strange reason calling it
with a pointer to a struct page is not incorrect in your code).
The previous version of this patch was compile tested on x86-64.
[1] http://ozlabs.org/~rusty/index.cgi/tech/2008-04-01.html
[2] In these cases, it is at level 5, "Do it right or it will always
break at runtime."
[3] At least mips and powerpc look very similar, and sparc also seems to
share a common ancestor with both; there seems to be quite some
degree of copy-and-paste coding here. The include/asm/highmem.h file
for these three archs mention x86 CPUs at its top.
[4] http://ozlabs.org/~rusty/index.cgi/tech/2008-03-30.html
[5] As an aside, could someone tell me why mn10300 uses unsigned long as
the first parameter of kunmap_atomic() instead of void *?

Replace inode_setattr with opencoded variants of it in all callers. This
moves the remaining call to vmtruncate into the filesystem methods where it
can be replaced with the proper truncate sequence.
In a few cases it was obvious that we would never end up calling vmtruncate
so it was left out in the opencoded variant:
spufs: explicitly checks for ATTR_SIZE earlier
btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier
ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above
In addition to that ncpfs called inode_setattr with handcrafted iattrs,
which allowed to trim down the opencoded variant.

The open and release block_device_operations are currently
called with the BKL held. In order to change that, we must
first make sure that all drivers that currently rely
on this have no regressions.
This blindly pushes the BKL into all .open and .release
operations for all block drivers to prepare for the
next step. The drivers can subsequently replace the BKL
with their own locks or remove it completely when it can
be shown that it is not needed.
The functions blkdev_get and blkdev_put are the only
remaining users of the big kernel lock in the block
layer, besides a few uses in the ioctl code, none
of which need to serialize with blkdev_{get,put}.
Most of these two functions is also under the protection
of bdev->bd_mutex, including the actual calls to
->open and ->release, and the common code does not
access any global data structures that need the BKL.

Work around a silicon bug in the ac97 reset functionality of the
mpc5200(b). The implementation of the ac97 "cold" reset is flawed.
If the sync and output lines are high when reset is asserted the
attached ac97 device may go into test mode. Avoid this by
reconfiguring the psc to gpio mode and generating the reset manually.
From MPC5200B User's Manual:
"Some AC97 devices goes to a test mode, if the Sync line is high
during the Res line is low (reset phase). To avoid this behavior the
Sync line must be also forced to zero during the reset phase. To do
that, the pin muxing should switch to GPIO mode and the GPIO control
register should be used to control the output lines."

Trivial conflicts in Documentation/feature-removal-schedule.txt
Much less trivial conflicts in arch/powerpc/kernel/time.c resolved as
per Thomas' earlier merge commit 47916be4e2 ("Merge branch
'powerpc.cherry-picks' into timers/clocksource")
KVM ended up having to put a pretty ugly wrapper around set_64bit()
in order to get the type right. Now set_64bit() takes the expected
u64 type, and this wrapper can be cleaned up.

The GPIO API was extended recently to include debounce functions, but
since the on-chip Blackfin GPIO modules don't support this stuff, make
a stub in the non-GPIOLIB case so drivers build properly.
