[Xen-devel] [PATCH v4 03/25] A collection of fixes to Xen common files

[<stefano.stabellini@xxxxxxxxxxxxx>]

From: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>

- call free_xenoprof_pages only ifdef CONFIG_XENOPROF;

- define PRI_stime as PRId64 in an header file;

- respect boundaries in is_kernel_*;

- implement is_kernel_rodata;

- guest_physmap_add_page should be ((void)0).


Changes in v4:

- fix guest_physmap_add_page;


Changes in v2:

- introduce CONFIG_XENOPROF;

- define _srodata and _erodata as const char*.
