I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by
SLAB.
I think its purpose was to have a callback after an object has been freed
to verify that the state is the constructor state again? The callback is
performed before each freeing of an object.
I would think that it is much easier to check the object state manually
before the free. That also places the check near the code object
manipulation of the object.
Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was
compiled with SLAB debugging on. If there would be code in a constructor
handling SLAB_DEBUG_INITIAL then it would have to be conditional on
SLAB_DEBUG otherwise it would just be dead code. But there is no such code
in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real
use of, difficult to understand and there are easier ways to accomplish the
same effect (i.e. add debug code before kfree).
There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be
clear in fs inode caches. Remove the pointless checks (they would even be
pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.
This is the last slab flag that SLUB did not support. Remove the check for
unimplemented flags from SLUB.

If device->num is zero we attempt to kmalloc() zero bytes. When SLUB is
enabled this returns a null pointer and take that as an allocation failure
and fail the device register. Check for no devices and avoid the

Architectures that don't support DMA can say so by adding a config NO_DMA
to their Kconfig file. This will prevent compilation of some dma specific
driver code. Also dma-mapping-broken.h isn't needed anymore on at least
s390. This avoids compilation and linking of otherwise dead/broken code.
Other architectures that include dma-mapping-broken.h are arm26, h8300,
m68k, m68knommu and v850. If these could be converted as well we could get
rid of the header file.

Ensure pages are uptodate after returning from read_cache_page, which allows
us to cut out most of the filesystem-internal PageUptodate calls.
I didn't have a great look down the call chains, but this appears to fixes 7
possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in
ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in
block2mtd. All depending on whether the filler is async and/or can return
with a !uptodate page.

The MPSC serial driver assumes that interrupt is always on to pick up the
DMA transmit ops that aren't submitted while the DMA engine is active.
However when irqs are off for a period of time such as operations under
kernel crash dump console messages do not show up due to additional DMA ops
are being dropped. This makes console writes to process through all the tx
DMAs queued up before submitting a new request.
Also, the current locking mechanism does not protect the hardware registers
and ring buffer when a printk is done during the serial write operations.
The additional per port transmit lock provides a finer granular locking and
protects registers being clobbered while printks are nested within UART
writes.

At present, the serial core always allows setserial in userspace to change the
port address, irq and base clock of any serial port. That makes sense for
legacy ISA ports, but not for (say) embedded ns16550 compatible serial ports
at peculiar addresses. In these cases, the kernel code configuring the ports
must know exactly where they are, and their clocking arrangements (which can
be unusual on embedded boards). It doesn't make sense for userspace to change
these settings.
Therefore, this patch defines a UPF_FIXED_PORT flag for the uart_port
structure. If this flag is set when the serial port is configured, any
attempts to alter the port's type, io address, irq or base clock with
setserial are ignored.
In addition this patch uses the new flag for on-chip serial ports probed in
arch/powerpc/kernel/legacy_serial.c, and for other hard-wired serial ports
probed by drivers/serial/of_serial.c.

Serial driver patch for the PMC-Sierra MSP71xx devices.
There are three different fixes:
1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard
16550 in that the THRE interrupt will not re-assert itself simply by
disabling and re-enabling the THRI bit in the IER, it is only re-enabled
if a character is actually sent out.
It appears that the "8250-uart-backup-timer.patch" in the "mm" tree
also fixes it so we have dropped our initial workaround. This patch now
needs to be applied on top of that "mm" patch.
2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature
which causes a new Busy Detect interrupt to be generated if it's busy
when the LCR is written. This fix saves the value of the LCR and
rewrites it after clearing the interrupt.
3 Workaround for interrupt/data concurrency issue: The SoC needs to
ensure that writes that can cause interrupts to be cleared reach the UART
before returning from the ISR. This fix reads a non-destructive register
on the UART so the read transaction completion ensures the previously
queued write transaction has also completed.

PCI drivers have the new_id file in sysfs which allows new IDs to be added
at runtime. The advantage is to avoid re-compilation of a driver that
works for a new device, but it's ID table doesn't contain the new device.
This mechanism is only meant for testing, after the driver has been tested
successfully, the ID should be added in source code so that new revisions
of the kernel automatically detect the device.
The implementation follows the PCI implementation. The interface is documented
in Documentation/pcmcia/driver.txt. Computations should be done in userspace,
so the sysfs string contains the raw structure members for matching.

wrapper which does the max PIO mode check; it worked by the pure luck
previously, pio[4] and pio_want[4] arrays were used with index == 255
so random PIO timings and base clock were set for the controller in the
passthrough mode, thankfully PIO timings and base clock were corrected
later by config_it821x_chipset_for_pio() call (but it was not called for
PIO-only devices during resume and for user requested PIO autotuning)
* remove config_it821x_chipset_for_pio() call from config_chipset_for_dma()
as the driver sets ->autotune to 1 and ->tuneproc does the proper job now

Start using faster versions of the ide_dma_end() and ide_dma_test_irq() methods
for the PCI0646U and newer chips that have the duplicate interrupt status bits
in the I/O mapped MRDMODE register, determing what methods to use at the driver
load time. Do some cleanup/renaming in the "old" ide_dma_test_irq() method too.

Fix several issues with the driver's procfs output:
- when testing if channel is enabled, the code looks at the "simplex" bits, not
at the real enable bits -- add #define for the primary channel enable bit;
- UltraDMA modes 0, 1, 3 for slave drive reported incorrectly due to using the
master drive's clock cycle resolution bit.
While at it, also perform the following cleanups:
- don't print extra newline before the first controller's dump;
- correct the chipset names (from CMDxxx to PCI-xxx)
- don't read from the registers which aren't used for dump;
- better align the table column sizes;
- rework UltraDMA mode dump code;
- remove PIO mode dump code that has never been finished;
- remove the duplicate interrupt status (the MRDMODE register bits mirror those
those in the CFR and ARTTIM23 registers) and fold the dump into single line;
- correct the style of the ?: operators...

The IDE core looks at the wrong bit when checking if the secondary channel is
enabled on PCI0646 -- CNTRL register bit 7 is read-ahead disable, bit 3 is the
correct one.
Starting with PCI0646U chip, the primary channel can also be enabled/disabled --
so, add 'enablebits' initializers to each 'ide_pci_device_t' structure, handling
the original PCI0646 via adding the init_setup() method and clearing the 'reg'
field there if necessary...

status bits are not coupled to DMA.

Fix the multiword DMA and drop the single-word DMA support (which nobody will
miss, I think). In order to do it, a number of changes was necessary:
- rename program_drive_counts() to program_cycle_times(), pass to it cycle's
total/active times instead of the clock counts, and convert them into the
active/recovery clocks there instead of cmd64x_tune_pio() -- this causes
quantize_timing() to also move;
- contrarywise, move all the code handling the address setup timing into
cmd64x_tune_pio(), so that setting MWDMA mode wouldn't change address setup;
- remove from the speedproc() method the bogus code pretending to set the DMA
timings by twiddling bits in the BMIDE status register, handle setting MWDMA
by just calling program_cycle_times(); while at it, improve the style of that
whole switch statement;
- stop fiddling with the DMA capable bits in the speedproc() method -- they do
not enable DMA, and are properly dealt with by the dma_host_{on,off} methods;
- don't set hwif->swdma_mask in the init_hwif() method anymore.
In addition to those changes, do the following:
- in cmd64x_tune_pio(), when writing to ARTTIM23 register preserve the interrupt
status bit, eliminate local_irq_{save|restore}() around this code as there's
*no* actual race with the interrupt handler, and move cmdprintk() to a more
fitting place -- after ide_get_best_pio_mode() call;
- make {arttim|drwtim}_regs arrays single-dimensional, indexed with drive->dn;
- rename {setup|recovery}_counts[] into more fitting {setup|recovery}_values[];
- in the speedproc() method, get rid of the duplicate reads/writes from/to the
UDIDETCRx registers and of the extra variable used to store the transfer mode
value after filtering, use another method of determining master/slave drive,
and cleanup useless parens;
- beautify cmdprintk() output here and there.
While at it, remove meaningless comment about the driver being used only on
UltraSPARC and long non-relevant RCS tag. :-)

Fold the now equivalent code in the ide_dma_check() method into a mere call to
ide_use_dma(). Make config_for_dma() return non-zero if DMA mode has been set
and call it from the ide_dma_check() method instead of ide_dma_on().
Defer writing the DMA timings to the chip registers until DMA is really turned
on (and do not enable IORDY for DMA).
Remove unneeded code from the init_hwif() method, improve its overall looks.
Rename the dma_start(), ide_dma_check(), and ide_dma_lostirq() methods, and
also use more proper hwif->dma_command, fix printk() and comment in the latter
one as well. While at it, cleanup style in several places.

Get rid of the 'pio_speed' member of 'ide_drive_t' that was only used by this
driver by storing the PIO mode timings in the 'drive_data' instead -- this
allows us to greatly simplify the process of "reloading" of the chip's timing
register and do it right in sl82c150_dma_off_quietly() and to get rid of two
extra arguments to config_for_pio() -- which got renamed to sl82c105_tune_pio()
and now returns a PIO mode selected, with ide_config_drive_speed() call moved
into the tuneproc() method, now called sl82c105_tune_drive() with the code to
set drive's 'io_32bit' and 'unmask' flags in its turn moved to its proper place
in the init_hwif() method.
Also, while at it, rename get_timing_sl82c105() into get_pio_timings() and get
rid of the code in it clamping cycle counts to 32 which was both incorrect and
never executed anyway...

This patch removes the use of the TG3_FLAG_5701_REG_WRITE_BUG flag.
It's logic is only used to set a function pointer and thus the
logic can be collapsed and the flag removed.

The reset was added a while back so that ASF could re-init whatever
MAC address it wanted to use after the MAC address was changed.
Instead of resetting, we can just keep MAC address 1 unchanged during
MAC address changes if MAC address 1 is different from MAC address 0.
This fixes 2 problems:
1. Bonding calls set_mac_address in contexts that cannot sleep.
It no longer sleeps with the chip reset removed.
2. When ASF shares the same MAC address as the NIC, it needs to
always do that even when the MAC address is changed.

This patch changes the NVRAM sizing procedure so that the driver can
take advantage of devices with 1:1 NVRAM strapping configurations. This
is useful in cases where the traditional NVRAM sizing method fails. In
the event that the flash size cannot be determined, the largest known
NVRAM size is used. The patch also removes support for 5755 NVRAM
devices that are not supported by Broadcom and adds explicit sizing for
this device.

1. Remove the check for skb->len greater than MTU when doing TSO.
When the destination has a smaller MSS than the source, a TSO packet
may be smaller than the MTU and we still need to process it as a TSO
packet.
2. On 5705A3 devices with TSO enabled, the DMA engine can hang due to a
hardware bug. This patch avoids the hanging condition by reducing the
DMA burst size.
