ACPI / APEI: Pass ghes and estatus separately to avoid a later copy
fix #28612342 commit f2a7e059aa7a6a22a6f4612f31ee29e726a3bfd0 upstream The NMI-like notifications scribble over ghes->estatus, before copying it somewhere else. If this interrupts the ghes_probe() code calling ghes_proc() on each struct ghes, the data is corrupted. All the NMI-like notifications should use a queued estatus entry from the beginning, instead of the ghes version, then copying it. To do this, break up any use of "ghes->estatus" so that all functions take the estatus as an argument. This patch just moves these ghes->estatus dereferences into separate arguments, no change in behaviour. struct ghes becomes unused in ghes_clear_estatus() as it only wanted ghes->estatus, which we now pass directly. This is removed. Signed-off-by: NJames Morse <james.morse@arm.com> Signed-off-by: NRafael J.
