Use hva_t, a.k.a. unsigned long, for the local variable that holds the
hypercall page address. On 32-bit KVM, gcc complains about using a u64
due to the implicit cast from a 64-bit value to a 32-bit pointer.
arch/x86/kvm/xen.c: In function ‘kvm_xen_write_hypercall_page’:
arch/x86/kvm/xen.c:300:22: error: cast to pointer from integer of
different size [-Werror=int-to-pointer-cast]
300 | page = memdup_user((u8 __user *)blob_addr, PAGE_SIZE);

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.
