[v3,00/15] Build fixes for musl libc

  A set of patches to fix build with musl libc. I also did a few cleanups wrt
macros and fixed a few scary compiler warnings while at it.

Please note that those are only compile tested on x86_64 with musl libc.

v2 has some code style fixes reported by checkpatch
v3 is a full reroll of the entire patch set to enable automatted tests
   and logic for patchwork patchset.

Natanael Copa (15):
  app/testpmd: replace uint with unsigned int
  net/cxgbe: replace uint with unsigned int
  bus/pci: add fallback for out[lwb]_p for non GNU libc
  bus/pci: factor out various ifdefs in pci_uio_ioport_{read,write}
  bus/fslmc: fix compile error with musl libc
  bus/fslmc: remove unused include of error.h
  net/nfp: build fix for musl libc
  app/test: include fcntl.h due to use of O_RDONLY
  app/test: fix setting of -D_GNU_SOURCE with meson
  bus/dpaa: use warn(3) instead of error(3) to improve portability
  bus/dpaa: fix warning: "__WORDSIZE" is not defined, evaluates to 0
  crypto/dpaa2_sec: build fix for musl libc
  crypto/dpaa2_sec: simplify pr_{debug,err,warn} macros
  net/netvsc: fix compile warning for fcntl.h include
  eal/linux: simplify debug message in sigbus_handler

When I try building I'm still getting this error

Thanks for the cleanup.

Some patches may deserve more reviews.
If you send a new version, please use --to-cmd devtools/get-maintainer.sh
so the maintainers will be Cc'ed.

All these patches are fixes and may be interesting to backport them
in the latest LTS or other stable releases.
In order to help with backporting, please fill "Fixes:" tag
and add Cc: stable when relevant.
The exact recommendation is described in this doc chapter:
http://doc.dpdk.org/guides/contributing/patches.html#commit-messages-body

In order to help, I already fixed 7 commit messages and merged them.
The remaining patches, requiring a v4, are:
  app/testpmd: replace uint with unsigned int
  net/cxgbe: replace uint with unsigned int
  bus/pci: add fallback for out[lwb]_p for non GNU libc
  bus/pci: factor out various ifdefs in pci_uio_ioport_{read,write}
  bus/dpaa: use warn(3) instead of error(3) to improve portability
  bus/dpaa: fix warning: "__WORDSIZE" is not defined, evaluates to 0
  crypto/dpaa2_sec: build fix for musl libc
  crypto/dpaa2_sec: simplify pr_{debug,err,warn} macros

If you intend to send a v4, I noticed a few more "uint" in the tree, I
suppose this is worth fixing them:
$ git grep -w uint
app/test-pmd/config.c:                   uint hash_key_len)
examples/tep_termination/vxlan.c:       uint vport_id;
  

A set of patches to fix build with musl libc. I also did a few cleanups wrt
macros and fixed a few scary compiler warnings while at it.

Please note that those are only compile tested on x86_64 with musl libc.

v2 has some code style fixes reported by checkpatch

v3 is a full reroll of the entire patch set to enable automatted tests
   and logic for patchwork patchset.

v4 rebase against main and deal with renames/moves.
   fix commit messages to make check-git-log.sh happy.
   improve error(3) -> warn(3) patch and clarify commit message.
   update __WORDSIZE patch to use RTE_ARCH_64
   add "Fixes:" tags
   add a couple of patches fro eal

Sorry that it took so long time to follow up.

Natanael Copa (8):
  app/testpmd: fix uint build error with musl libc
  net/cxgbe: fix uint build error with musl libc
  bus/pci: add fallback for out* for non GNU libc
  bus/dpaa: use warn instead of error to improve portability
  bus/dpaa: fix detection of 64 bit arch
  common/dpaax: build fix for musl libc
  common/dpaax: simplify pr debug/err/warn macros
  eal: add missing include to fix build with musl libc

No problem, that's very good to receive these fixes. Thanks

- I suppose you got the mails with the build errors from the robot.
Build is broken in dpaa (missing a few <err.h> includes).
https://travis-ci.com/github/ovsrobot/dpdk/jobs/429242867#L1005

- I still see a uint use in drivers/net/igc.
How about:

Please could send a new version fixing the build issues?
If you don't have time, just ask for someone to follow-up,
we probably can find a volunteer.
  

Hi,

Sorry, I thought I would be able to allocate time yesterday but got distracted.

I would appreciate if someone else could follow up, since I don’t know when I´ll find time for it.

Thanks!

I am taking over the series, adding multiple fixes
to make Alpine fully supported.
I will send a v5 soon.
