Subject: [PATCH v2 1/2] asm-generic: Remove pci.h copying remaining code to x86
Date: Sun, 17 Jul 2022 12:34:52 +0900 [thread overview]
Message-ID: <20220717033453.2896843-2-shorne@gmail.com> (raw)
In-Reply-To: <20220717033453.2896843-1-shorne@gmail.com>
The generic pci.h header now only provides a definition of
pci_get_legacy_ide_irq which is used by architectures that support PNP.
Of the architectures that use asm-generic/pci.h this is only x86.
This patch removes the old pci.h in order to make room for a new
pci.h to be used by arm64, riscv, openrisc, etc.
The existing code in pci.h is moved out to x86. On other architectures
we clean up any outstanding references.
