Subject: [RFC PATCH kernel 07/17] x86/dma: Revert "x86: Remove unnecessary architecture-specific <asm/device.h>"
Date: Wed, 16 Sep 2026 21:51:47 +1000 [thread overview]
Message-ID: <20260916115159.1938195-8-aik@amd.com> (raw)
In-Reply-To: <20260916115159.1938195-1-aik@amd.com>
The trusted guest device DMA setup is going to distinguish
encrypted and decrypted memory and dev_archdata is a logical place for
it.
This reverts commit c256d2a8adf2f5670ca262979c451ec4c1108e38.
