Subject: [PATCH kernel 0/2] powerpc/mm_iommu: Fix potential deadlock
Date: Fri, 29 Mar 2019 16:46:39 +1100	[thread overview]
Message-ID: <20190329054641.48597-1-aik@ozlabs.ru> (raw)

I was trying the kernel with DEBUG_LOCKDEP and saw warnings. 1/2 is preparing the fix
to make 2/2 reviewable and 2/2 is the actual fix.


This is based on sha1
a3ac7917b730 Linus Torvalds "Revert "parport: daisy: use new parport device model"".

Please comment. Thanks.
