Subject: [PATCH v6 11/18] ACPI / APEI: Remove silent flag from ghes_read_estatus()
Date: Fri, 21 Sep 2018 23:16:58 +0100 [thread overview]
Message-ID: <20180921221705.6478-12-james.morse@arm.com> (raw)
In-Reply-To: <20180921221705.6478-1-james.morse@arm.com>
Subsequent patches will split up ghes_read_estatus(), at which
point passing around the 'silent' flag gets annoying. This is to
suppress prink() messages, which prior to 42a0bb3f7138 ("printk/nmi:
generic solution for safe printk in NMI"), were unsafe in NMI context.
We don't need to do this anymore, remove the flag. printk() messages
are batched in a per-cpu buffer and printed via irq-work, or a call
back from panic().
