Subject: [PATCH 0/3] ACPI: Re-factor and remove ./drivers/acpi/atomicio.[ch]
Date: Fri, 20 Jan 2012 19:13:18 -0700	[thread overview]
Message-ID: <20120121021318.14723.45698.stgit@amt.stowe> (raw)

I recently submitted a patch series that re-factored some existing
work that Huang Ying introduced adding support for accessing ACPI
generic registers, backed by Memory Mapped I/O (MMIO), while within
interrupt context:
  Original series: http://marc.info/?l=linux-acpi&m=128769263327206&w=2
  Follow on series: http://marc.info/?l=linux-kernel&m=132070825520957&w=2

An underlying goal has been to re-factor ./drivers/acpi/atomicio.c into
./drivers/acpi/osl.c, providing equivalent functionality but in a more
generalized manner, to allow usage in non-specific (i.e. APEI) contexts
and remove atomicio.c.

In the most recent follow on series, there ended up being additions to
atomicio.c that coincided with the attempt to remove it and as such, the
series final removal patch could not be taken without first pulling the
additions into osl.c.  The fact that the follow on series conversion
patch - commit 700130b41f4 - was taken has inadvertently created
regressions with respect to the recent atomicio.c additions due to the
conversion patch effectively making atomicio.c obsolete.

The additions were commit 04c25997c97 "ACPI, Add 64bit read/write
support to atomicio on i386" and commit 76da3fb3575 "ACPI, Add RAM
mapping support to ACPI atomic IO support".

This patch series addresses both of these issues, bringing in the
additional functionality into the re-factored files (apei-base.c and
osl.c) and then again, reintroduces the patch to remove
./drivers/acpi/atomicio.[ch].
