[ Upstream commit5ec32a3e40] The cs5535-mfd driver uses CPU-specific data that is not available for ARCH=um builds, so don't allow it to be built for UML. Prevents these build errors: In file included from ../arch/x86/include/asm/olpc.h:7, from ../drivers/mfd/cs5535-mfd.c:17: ../arch/x86/include/asm/geode.h: In function ‘is_geode_gx’: ../arch/x86/include/asm/geode.h:16:31: error: ‘struct cpuinfo_um’ has no member named ‘x86_vendor’ 16 | return ((boot_cpu_data.x86_vendor == X86_VENDOR_NSC) && ../arch/x86/include/asm/geode.h:16:46: error: ‘X86_VENDOR_NSC’ undeclared (first use in this function); did you mean ‘X86_VENDOR_ANY’? 16 | return ((boot_cpu_data.x86_vendor == X86_VENDOR_NSC) && ../arch/x86/include/asm/geode.h:17:31: error: ‘struct cpuinfo_um’ has no member named ‘x86’ 17 | (boot_cpu_data.x86 == 5) && ../arch/x86/include/asm/geode.h:18:31: error: ‘struct cpuinfo_um’ has no member named ‘x86_model’ 18 | (boot_cpu_data.x86_model == 5)); ../arch/x86/include/asm/geode.h: In function ‘is_geode_lx’: ../arch/x86/include/asm/geode.h:23:31: error: ‘struct cpuinfo_um’ has no member named ‘x86_vendor’ 23 | return ((boot_cpu_data.x86_vendor == X86_VENDOR_AMD) && ../arch/x86/include/asm/geode.h:23:46: error: ‘X86_VENDOR_AMD’ undeclared (first use in this function); did you mean ‘X86_VENDOR_ANY’? 23 | return ((boot_cpu_data.x86_vendor == X86_VENDOR_AMD) && ../arch/x86/include/asm/geode.h:24:31: error: ‘struct cpuinfo_um’ has no member named ‘x86’ 24 | (boot_cpu_data.x86 == 5) && ../arch/x86/include/asm/geode.h:25:31: error: ‘struct cpuinfo_um’ has no member named ‘x86_model’ 25 | (boot_cpu_data.x86_model == 10)); Fixes:68f5d3f3b6("um: add PCI over virtio emulation driver") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20221201012541.11809-1-rdunlap@infradead.org Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
