mm: correctly update zone->managed_pages

2013-07-03T23:07:33Z

Enhance adjust_managed_page_count() to adjust totalhigh_pages for highmem pages. And change code which directly adjusts totalram_pages to use adjust_managed_page_count() because it adjusts totalram_pages, totalhigh_pages and zone->managed_pages altogether in a safe way. Remove inc_totalhigh_pages() and dec_totalhigh_pages() from xen/balloon driver bacause adjust_managed_page_count() has already adjusted totalhigh_pages. This patch also fixes two bugs: 1) enhances virtio_balloon driver to adjust totalhigh_pages when reserve/unreserve pages. 2) enhance memory_hotplug.c to adjust totalhigh_pages when hot-removing memory. We still need to deal with modifications of totalram_pages in file arch/powerpc/platforms/pseries/cmm.c, but need help from PPC experts. [akpm@linux-foundation.org: remove ifdef, per Wanpeng Li, virtio_balloon.c cleanup, per Sergei] [akpm@linux-foundation.org: export adjust_managed_page_count() to modules, for drivers/virtio/virtio_balloon.c] Signed-off-by: Jiang Liu Cc: Chris Metcalf Cc: Rusty Russell Cc: "Michael S.

xen: Convert printks to pr_

2013-06-28T15:19:58Z

Convert printks to pr_ (excludes printk(KERN_DEBUG...) to be more consistent throughout the xen subsystem. Add pr_fmt with KBUILD_MODNAME or "xen:" KBUILD_MODNAME Coalesce formats and add missing word spaces Add missing newlines Align arguments and reflow to 80 columns Remove DRV_NAME from formats as pr_fmt adds the same content This does change some of the prefixes of these messages but it also does make them more consistent.

xen: balloon: allow PVMMU interfaces to be compiled out

2012-11-29T12:59:13Z

The ARM platform has no concept of PVMMU and therefor no HYPERVISOR_update_va_mapping et al. Allow this code to be compiled out when not required. In some similar situations (e.g. P2M) we have defined dummy functions to avoid this, however I think we can/should draw the line at dummying out actual hypercalls.

xen: balloon: don't include e820.h

This breaks on !X86 and AFAICT is not required on X86 either. Acked-by: Stefano Stabellini Signed-off-by: Ian Campbell Signed-off-by: Konrad Rzeszutek Wilk

xen/balloon: Avoid OOM when requesting highmem

2011-11-16T17:13:43Z

If highmem pages are requested from the balloon on a system without highmem, the implementation of alloc_xenballooned_pages will allocate all available memory trying to find highmem pages to return. Allow low memory to be returned when highmem pages are requested to avoid this loop. Signed-off-by: Daniel De Graaf Signed-off-by: Konrad Rzeszutek Wilk

xen: Add module.h to modular drivers/xen users.

2011-10-31T23:32:11Z

Previously these drivers just got module.h implicitly, but we are cleaning that up and it will be no longer. Call out the real users of it. Signed-off-by: Paul Gortmaker
