Subject: [PATCH 0/1] Fix siw CQ processing for 32 bit archtecture support
Date: Mon,  5 Aug 2019 16:17:07 +0200	[thread overview]
Message-ID: <20190805141708.9004-1-bmt@zurich.ibm.com> (raw)

Change driver/user shared (mmapped) CQ notification flags field
to unaligned 32-bits size. This enables building siw on 32-bit
architectures.

The original idea to introduce test_and_clear_bit() for testing CQ
arming during CQE processing was abandoned, since it would
require architecture spcific siw-abi notation: test_and_clear_bit()
expects an unsigned long field, which has an architecture specific
size.

This patch applies to 5.3-rc3.

Bernard Metzler (1):
  Make user mmapped CQ arming flags field 32 bit size to remove 64 bit
    architecture dependency of siw.
