Pass the work_struct pointer to the work function rather than context data.
The work function can use container_of() to work out the data.
For the cases where the container of the work_struct may go away the moment the
pending bit is cleared, it is made possible to defer the release of the
structure by deferring the clearing of the pending bit.
To make this work, an extra flag is introduced into the management side of the
work_struct. This governs auto-release of the structure upon execution.
Ordinarily, the work queue executor would release the work_struct for further
scheduling or deallocation by clearing the pending bit prior to jumping to the
work function. This means that, unless the driver makes some guarantee itself
that the work_struct won't go away, the work function may not access anything
else in the work_struct or its container lest they be deallocated.. This is a
problem if the auxiliary data is taken away (as done by the last patch).
However, if the pending bit is *not* cleared before jumping to the work
function, then the work function *may* access the work_struct and its container
with no problems. But then the work function must itself release the
work_struct by calling work_release().
In most cases, automatic release is fine, so this is the default. Special
initiators exist for the non-auto-release case (ending in _NAR).

Separate delayable work items from non-delayable work items be splitting them
into a separate structure (delayed_work), which incorporates a work_struct and
the timer_list removed from work_struct.
The work_struct struct is huge, and this limits it's usefulness. On a 64-bit
architecture it's nearly 100 bytes in size. This reduces that by half for the
non-delayable type of event.

arch/mips/kernel/linux32.c have similar compatible code for O32, but
ipc/compat.c seems more complete. We can use it for both N32 and O32.

This allows any secondary CPU thread also to become boot cpu for
POWER5. The patch is required to solve kdump boot issue when the
kdump kernel is booted with parameter "maxcpus=1". XICS init code
tries to match the current boot cpu id with "reg" property in each CPU
node in the device tree. But CPU node is created only for primary
thread CPU ids and "reg" property only reflects primary CPU ids. So
when a kernel is booted on a secondary cpu thread above condition will
never meet and the default distribution server is left as zero. This
leads to route the interrupts to CPU 0, but which is not online at
this time.
We use ibm,ppc-interrupt-server#s to check for both primary and
secondary CPU ids. Accordingly default distribution server value is
initialized from "ibm,ppc-interrupt-gserver#s" property. We loop
through ibm,ppc-interrupt-gserver#s property to find the global
distribution server from the last entry that matches with boot cpuid.
