MACH_VIRT is already defined, so we just add VIRTIO_BLK, VIRTIO_NET

ARM: pxa: add defconfig covering all the boards
Add a defconfig covering all known pxa board, ie. all selectable machine

- aggregation of all known defconfigs by cat
am200epdkit_defconfig
cm_x2xx_defconfig
cm_x300_defconfig
colibri_pxa270_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

corrupts the data in the sector by splicing some of the original

target: Fix race for SCF_COMPARE_AND_WRITE_POST checking
This patch addresses a race + use after free where the first
stage of COMPARE_AND_WRITE in compare_and_write_callback()
is rescheduled after the backend sends the secondary WRITE,
resulting in second stage compare_and_write_post() callback
completing in target_complete_ok_work() before the first
can return.
Because current code depends on checking se_cmd->se_cmd_flags
after return from se_cmd->transport_complete_callback(),
this results in first stage having SCF_COMPARE_AND_WRITE_POST
set, which incorrectly falls through into second stage CAW
processing code, eventually triggering a NULL pointer
dereference due to use after free.
To address this bug, pass in a new *post_ret parameter into
se_cmd->transport_complete_callback(), and depend upon this

iscsi-target: Fix rx_login_comp hang after login failure
This patch addresses a case where iscsi_target_do_tx_login_io()
fails sending the last login response PDU, after the RX/TX
threads have already been started.
The case centers around iscsi_target_rx_thread() not invoking
allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs
from the failure path, resulting in RX thread hanging
indefinately on iscsi_conn->rx_login_comp.

ARM: 8454/1: OF implies OF_FLATTREE
On the ARM architecture, individual platforms select CONFIG_USE_OF if they
need it, but all device tree code is keyed off CONFIG_OF. When building
a platform without DT support and manually enabling CONFIG_OF, we now
get a number of build errors, e.g.
arch/arm/kernel/devtree.c: In function 'setup_machine_fdt':
arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration]
We could now try to separate the use case of booting from DT vs. the
case of using the dynamic implementation, but that seems more complicated
than it can gain us.
This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM
and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little
extra code when we just want the dynamic OF implementation, but that seems
like a rather obscure case, and this version solves all CONFIG_OF related
randconfig regressions.

If more than 1024 event channels are bound to a evtchn device then it
possible (even with well behaved applications) for the ring to
overflow and events to be lost (reported as an -EFBIG error).
Dynamically increase the size of the ring so there is always enough
space for all bound events. Well behaved applicables that only unmask
events after draining them from the ring can thus no longer lose
events.
However, an application could unmask an event before draining it,
allowing multiple entries per port to accumulate in the ring, and a
overflow could still occur. So the overflow detection and reporting
is retained.
The ring size is initially only 64 entries so the common use case of
an application only binding a few events will use less memory than
before. The ring size may grow to 512 KiB (enough for all 2^17
possible channels). This order 7 kmalloc() may fail due to memory
fragmentation, so we fall back to trying vmalloc().
