The size of the GHCB scratch area is limited to 16 KiB (GHCB_SCRATCH_AREA_LIMIT), so there is no need for it to be a u64. This fixes a build error on 32-bit systems: i686-linux-gnu-ld: arch/x86/kvm/svm/sev.o: in function `sev_es_string_io: sev.c:(.text+0x110f): undefined reference to `__udivdi3' Cc: stable@vger.kernel.org Fixes: 019057bd73d1 ("KVM: SEV-ES: fix length of string I/O") Reported-by: Naresh Kamboju <naresh.kamboju@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
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.
