stable-rc linux-6.6.y: Queues: tinyconfig: undefined reference to `irq_work_queue'

[Naresh Kamboju]

Most of the tinyconfigs are failing on stable-rc linux-6.6.y.

Build errors:
--------------

task_work.c:(.text+0x190): undefined reference to `irq_work_queue'
task_work.c:(.text+0x190): relocation truncated to fit:
R_AARCH64_CALL26 against undefined symbol `irq_work_queue'

Anders bisected this regression and found,
# first bad commit:
  [63ad09867ee1affe4b7a5914deeb031d5b4c0be2]
  task_work: Add TWA_NMI_CURRENT as an additional notify mode.

Would you mind to cherry-pick
	cec6937dd1aae ("task_work: make TWA_NMI_CURRENT handling conditional on IRQ_WORK")

I'm able to to build the arm64 tinyconfig on the queue/6.6 branch with
this (while it fails without).
