During ghes_proc() we use ghes_ack_error() to tell an external agent we are done with these records and it can re-use the memory. rc may hold an error returned by ghes_read_estatus(), ENOENT causes us to skip ghes_ack_error() (as there is nothing to ack), but rc may also by EIO, which gets supressed. ghes_clear_estatus() is where we mark the records as processed for non GHESv2 error sources, and already spots the ENOENT case as buf_paddr is set to 0 by ghes_read_estatus(). Move the ghes_ack_error() call in here to avoid extra logic with the return code in ghes_proc(). This enables GHESv2 acking for NMI-like error sources. This is safe as the buffer is pre-mapped by map_gen_v2() before the GHES is added to any NMI handler lists. This same pre-mapping step means we can't receive an error from apei_read()/write() here as apei_check_gar() succeeded when it was mapped, and the mapping was cached, so the address can't be rejected at runtime. Remove the error-returns as this is now called from a function with no return. Signed-off-by: James Morse <james.morse@arm.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
