Sean Christopherson 11633f6950 KVM: VMX: Always inline eVMCS read/write helpers
Tag all evmcs_{read,write}() helpers __always_inline so that they can be
freely used in noinstr sections, e.g. to get the VM-Exit reason in
vcpu_vmx_enter_exit() (in a future patch).  For consistency and to avoid
more spot fixes in the future, e.g. see commit 010050a863 ("x86/kvm:
Always inline evmcs_write64()"), tag all accessors even though
evmcs_read32() is the only anticipated use case in the near future.  In
practice, non-KASAN builds are all but guaranteed to inline the helpers
anyways.

  vmlinux.o: warning: objtool: vmx_vcpu_enter_exit+0x107: call to evmcs_read32()
                               leaves .noinstr.text section

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.
