commit ce9084ba0d1d8030adee7038ace32f8d9d423d0f upstream. Turn ARCH_USE_MEMREMAP_PROT into a generic Kconfig symbol, and fix the dependency expression to reflect that AMD_MEM_ENCRYPT depends on it, instead of the other way around. This will permit ARCH_USE_MEMREMAP_PROT to be selected by other architectures. Note that the encryption related early memremap routines in arch/x86/mm/ioremap.c cannot be built for 32-bit x86 without triggering the following warning: arch/x86//mm/ioremap.c: In function 'early_memremap_encrypted': >> arch/x86/include/asm/pgtable_types.h:193:27: warning: conversion from 'long long unsigned int' to 'long unsigned int' changes value from '9223372036854776163' to '355' [-Woverflow] #define __PAGE_KERNEL_ENC (__PAGE_KERNEL | _PAGE_ENC) ^~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/x86//mm/ioremap.c:713:46: note: in expansion of macro '__PAGE_KERNEL_ENC' return early_memremap_prot(phys_addr, size, __PAGE_KERNEL_ENC); which essentially means they are 64-bit only anyway. However, we cannot make them dependent on CONFIG_ARCH_HAS_MEM_ENCRYPT, since that is always defined, even for i386 (and changing that results in a slew of build errors) So instead, build those routines only if CONFIG_AMD_MEM_ENCRYPT is defined.

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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
