In every hypervisor except for xen pv time ops are initialized in init_hypervisor_platform(). Xen PV domains initialize time ops in x86_init.paging.pagetable_init(), by calling xen_setup_shared_info() which is a poor design, as time is needed prior to memory allocator. xen_setup_shared_info() is called from two places: during boot, and after suspend. Split the content of xen_setup_shared_info() into three places: 1. add the clock relavent data into new xen pv init_platform vector, and set clock ops in there. 2. move xen_setup_vcpu_info_placement() to new xen_pv_guest_late_init() call. 3. Re-initializing parts of shared info copy to xen_pv_post_suspend() to be symmetric to xen_pv_pre_suspend Signed-off-by: Pavel Tatashin <pasha.tatashin@oracle.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: steven.sistare@oracle.com Cc: daniel.m.jordan@oracle.com Cc: linux@armlinux.org.uk Cc: schwidefsky@de.ibm.com Cc: heiko.carstens@de.ibm.com Cc: john.stultz@linaro.org Cc: sboyd@codeaurora.org Cc: hpa@zytor.com Cc: douly.fnst@cn.fujitsu.com Cc: peterz@infradead.org Cc: prarit@redhat.com Cc: feng.tang@intel.com Cc: pmladek@suse.com Cc: gnomes@lxorguk.ukuu.org.uk Cc: linux-s390@vger.kernel.org Cc: boris.ostrovsky@oracle.com Cc: jgross@suse.com Cc: pbonzini@redhat.com Link: https://lkml.kernel.org/r/20180719205545.16512-13-pasha.tatashin@oracle.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.
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.
