[PATCH] drm/syncobj: Avoid kmalloc(GFP_KERNEL) under spinlock

[PATCH] drm/syncobj: Avoid kmalloc(GFP_KERNEL) under spinlock

[Chunming Zhou]

drivers/gpu/drm/drm_syncobj.c:202:4-14: ERROR: function drm_syncobj_find_signal_pt_for_point called on line 390 inside lock on line 389 but uses GFP_KERNEL

  Find functions that refer to GFP_KERNEL but are called with locks held.

Generated by: scripts/coccinelle/locks/call_kern.cocci

v2:
syncobj->timeline still needs protect.

v3:
use a global signaled fence instead of re-allocation.

v4:
Don't need moving lock.
Don't expose func.

v5:
rename func and directly return.

Tested by: syncobj_wait and ./deqp-vk -n dEQP-VK.*semaphore* with
lock debug kernel options enabled.

Could this be used by drm_syncobj_assign_null_handle too? Maybe as a separate patch?
