The device tree version of Versatile AP/PB never had LED support
so we are missing LEDs from our hardware boards. Add this as
syscon LEDs like we did for Integrator and Juno. We need to
spawn devices in the syscon with "simple-mfd" for this to work.

The Versatile now only has device tree boot support, and the
device tree version does not support CONFIG_LEDS_VERSATILE.
Instead select CONFIG_LEDS_SYSCON and MFD_SYSCON, so we can
get LEDs support from the same generic driver that drives
most other ARM reference boards.

Add a defconfig covering all known pxa board, ie. all selectable machine
files in arch/arm/mach-pxa/*.c.
This defconfig was built by doing :
- aggregation of all known defconfigs by cat
am200epdkit_defconfig
cm_x2xx_defconfig
cm_x300_defconfig
colibri_pxa270_defconfig
colibri_pxa300_defconfig
corgi_defconfig
em_x270_defconfig
eseries_pxa_defconfig
ezx_defconfig
h5000_defconfig
imote2_defconfig
lpd270_defconfig
lubbock_defconfig
magician_defconfig
mainstone_defconfig
multi_v7_defconfig

pxa255-idp_defconfig
pxa3xx_defconfig
raumfeld_defconfig
spitz_defconfig
trizeps4_defconfig
viper_defconfig
xcep_defconfig
zeus_defconfig
- manual make menuconfig to ensure :
- all pxa implementation were selected
- all drivers were transformed into modules rather than builtin
=> as a consequence this single kernel will rely on an initramfs
=> as kernel size matters on pxa, each machine can take the subset
of modules required for it to work
- all missed configurations are selected verified by :
=> grep -i pxa .config | grep "is not set"
=> this should only show the left on purpose options (either not
selectable or sharpsl exception below)
- CONFIG_PXA_SHARPSL was disabled
This breaks the boot very early on any non Sharp platform, see
head-sharpsl.S
This defconfig was tested as booting up to the login phase on :
- lubbock (pxa25x)
- mainstone (pxa27x)
- zylonite (pxa3xx)
The completion of this work will require to :
- parse manually all the arch/arm/mach-pxa/*c files, look for all
platform devices added, and verify they are all in pxa_defconfig
- do the same to ensure all pxa specific drivers (leds, gpio, ...) are
included

If the driver calls skb_set_hash even with a zero hash, that
indicates to the stack that the hash calculation is offloaded
in hardware. So the Stack doesn't do a SW hash which is required
for load balancing if the user decides to turn of rx-hashing
on our device.
This patch fixes the path so that we do not call skb_set_hash
if the feature is disabled.

This is the i40e equivalent of commit c762dff24c06 ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").
As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.
In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.
The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.

The BSP team noticed that there is spin/mutex lock issue on sh-sci when
CPUFREQ is used. The issue is that the notifier function may call
mutex_lock() while the spinlock is held, which can lead to a BUG().
This may happen if CPUFREQ is changed while another CPU calls
clk_get_rate().
Taking the spinlock was added to the notifier function in commit
e552de2413edad1a ("sh-sci: add platform device private data"), to
protect the list of serial ports against modification during traversal.
At that time the Common Clock Framework didn't exist yet, and
clk_get_rate() just returned clk->rate without taking a mutex.
Note that since commit d535a2305facf9b4 ("serial: sh-sci: Require a
device per port mapping."), there's no longer a list of serial ports to
traverse, and taking the spinlock became superfluous.
To fix the issue, just remove the cpufreq notifier:
1. The notifier doesn't work correctly: all it does is update stored
clock rates; it does not update the divider in the hardware.
The divider will only be updated when calling sci_set_termios().
I believe this was broken back in 2004, when the old
drivers/char/sh-sci.c driver (where the notifier did update the
divider) was replaced by drivers/serial/sh-sci.c (where the
notifier just updated port->uartclk).
Cfr. full-history-linux commits 6f8deaef2e9675d9 ("[PATCH] sh: port
sh-sci driver to the new API") and 3f73fe878dc9210a ("[PATCH]
Remove old sh-sci driver").
2. On modern SoCs, the sh-sci parent clock rate is no longer related
to the CPU clock rate anyway, so using a cpufreq notifier is
futile.

Another iscsi target that cannot handle large IOs, but does not tell us
a limit.
The Synology iSCSI targets report:
Block limits VPD page (SBC):
Write same no zero (WSNZ): 0
Maximum compare and write length: 0 blocks
Optimal transfer length granularity: 0 blocks
Maximum transfer length: 0 blocks
Optimal transfer length: 0 blocks
Maximum prefetch length: 0 blocks
Maximum unmap LBA count: 0
Maximum unmap block descriptor count: 0
Optimal unmap granularity: 0
Unmap granularity alignment valid: 0
Unmap granularity alignment: 0
Maximum write same length: 0x0 blocks
and the size of the command it can handle seems to depend on how much
memory it can allocate at the time. This results in IO errors when
handling large IOs. This patch just has us use the old 1024 default
sectors for this target by adding it to the scsi blacklist. We do not
have good contacs with this vendors, so I have not been able to try and
fix on their side.
I have posted this a long while back, but it was not merged. This
version just fixes it up for merge/patch failures in the original
version.

Dmitry reported that he was able to reproduce the WARN_ON_ONCE that
fires in locks_free_lock_context when the flc_posix list isn't empty.
The problem turns out to be that we're basically rebuilding the
file_lock from scratch in fcntl_setlk when we discover that the setlk
has raced with a close. If the l_whence field is SEEK_CUR or SEEK_END,
then we may end up with fl_start and fl_end values that differ from
when the lock was initially set, if the file position or length of the
file has changed in the interim.
Fix this by just reusing the same lock request structure, and simply
override fl_type value with F_UNLCK as appropriate. That ensures that
we really are unlocking the lock that was initially set.
While we're there, make sure that we do pop a WARN_ON_ONCE if the
removal ever fails. Also return -EBADF in this event, since that's
what we would have returned if the close had happened earlier.

IRQENB_HW_PEN bit is set in irqclr so that all interrupts get cleared
later so let IRQENB_HW_PEN be cleared by that.
Without this patch wakeup events from TSC_ADC do not work because pending
interrupts in TSC_ADC were causing HW_PEN interrupt, needed for wake from

For large sparse or fragmented files, checking every single entry in
the bmapbt on every operation is prohibitively expensive. Especially
as such checks rarely discover problems during normal operations on
high extent coutn files. Our regression tests don't tend to exercise
files with hundreds of thousands to millions of extents, so mostly
this isn't noticed.
However, trying to run things like xfs_mdrestore of large filesystem
dumps on a debug kernel quickly becomes impossible as the CPU is
completely burnt up repeatedly walking the sparse file bmapbt that
is generated for every allocation that is made.
Hence, if the file has more than 10,000 extents, just don't bother
with walking the tree to check it exhaustively. The btree code has
checks that ensure that the newly inserted/removed/modified record
is correctly ordered, so the entrie tree walk in thses cases has
limited additional value.

strsep() modifies its first argument. Make the pointer passed to kfree()
match the return value of kmalloc().

Avoid truncating the tag argument of target_submit_tmr() to a
32-bit number if the caller passes a 64-bit number.

The num_node_acls member in struct se_portal_group is modified
by several functions but is never read. Hence remove it.

The capability of setting hw_block_size was added along with 9c1cd1b68
"target/user: Only support full command pass-through", though default
setting override the user specified value during the enabling of device,
which called by target_configure_device() to set block_size matching
hw_block_size, result in user not able to set different block size other
than default 512.
This patch would use existing hw_block_size value if already set, otherwise
it would be set to default value(512).
Update: Fix the coding style issue.
(Drop unnecessary re-export of dev->dev_attrib.block_size - nab)

As reported by Dan, isert_create_device_ib_res() failure within
isert_device_get() can potentially return a postive value,
resulting in ERR_PTR() triggering a NULL pointer dereference.
Caught by the static checker:
drivers/infiniband/ulp/isert/ib_isert.c:423 isert_device_get()
error: passing non negative 1 to ERR_PTR

Add the 'tag' attribute to FC node ACLs. This is not used by kernel code,
but gives userspace a place to store a tag string. This is used to provide
support for initiator groups in targetcli.
Just copy iscsi's implementation for tcm_fc. A few other fabrics that
support acls also need this, to be submitted separately after the holidays.
