The patch titled
verify_dynamic_kobject_allocation: dont use kmalloc()
has been removed from the -mm tree. Its filename was
verify_dynamic_kobject_allocation-dont-use-kmalloc.patch
This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: verify_dynamic_kobject_allocation: dont use kmalloc()
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
- It's called very early from the firmware code and goes oops.
- Adding a GFP_KERNEL allocation into the previously-atomic
kobject_init() was a step backwards.
It's 128 bytes, which is liveable with.
