set_fs() now that there is no need for that any more. To properly

because __PAGE_OFFSET is defined using _AC itself and thus never needs
the cast anyway.

Use kvzalloc() in __iommu_alloc_buffer() instead of open-coding it.

When skbuff is fragment, we exit immediately and leave ip_hdrlen() as
unused. And remove the unnecessary local variable fragment.

Add a generic kretprobe trampoline handler for unifying
the all cloned /arch/* kretprobe trampoline handlers.
The generic kretprobe trampoline handler is based on the

It has frame pointer checking, kprobe_busy_begin/end and
return addres
