The patch titled
asm-i386/atomic.h: local_irq_save should be used instead of local_irq_disable
has been removed from the -mm tree. Its filename is
asm-i386-atomich-local_irq_save-should-be-used-instead-of-local_irq_disable.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: lepton <ytht.net@xxxxxxxxx>
atomic_add_return() if CONFIG_M386 can accidentally enable local interrupts.
Signed-off-by: Lepton Wu <ytht.net@xxxxxxxxx>
