Remove include of <mach/dma.h> from mach-tegra/apbio.c; since the DMA

When creating an L2TPv3 Ethernet session, if register_netdev() should fail for
any reason (for example, automatic naming for "l2tpeth%d" interfaces hits the
32k-interface limit), the netdev is freed in the error path. However, the
l2tp_eth_sess structure's dev pointer is left uncleared, and this results in
l2tp_eth_delete() then attempting to unregister the same netdev later in the
session teardown. This results in an oops.
To avoid this, clear the session dev pointer in the error path.

- target: Re-add explict zeroing of INQUIRY bounce buffer memory to

during v3.7-rc1, and hit >= v3.6.3 stable. (nab + paolo)
- iscsi-target: Fix a long-standing missed R2T wakeup race in TX
thread processing when using a single queue slot. (Roland)
Thanks to Roland & PureStorage team for helping to track down this
long standing race with iscsi-target single queue slot operation.
Also, the tcm_fc(FCoE) regression bug that was observed recently with
-rc2 code has also been resolved with the cancel_delayed_work() return
bugfix (commit c0158ca64da5: "workqueue: cancel_delayed_work() should

Zou, MDR, Robert Love @ Intel for helping to track this down."

Subject: frv: split ret_from_fork, simplify kernel_thread() a lot
The problem is that the userspace registers are completely cleared when a
kernel thread is created and all subsequent user threads are then copied from
that. Unfortunately, however, the TBR and PSR registers are restored from the
pt_regs and the values they should be set to are clobbered by the memset.
Instead, copy across the old user registers as normal, and then merely alter
GR8 and GR9 in it if we're going to execute a kernel thread.

Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is
incorrectly loaded into the threadinfo flags rather than the threadinfo
preemption count.
Unfortunately, the code cannot be simply converted to use
preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to
cut down on the cost of actually disabling interrupts and thus
local_irq_enable() doesn't actually enable interrupts.

gcc-4.1.2 inlines weak functions, which causes FRV to fail when the dummy
thread_info_cache_init() gets inlined into start_kernel().

Don't let objcopy transfer the GNU build_id note into the loadable image as it
is located at address 0 and the image ends up >3G in size.
