FWIW, it was removed and reintroduced as one of the customers wanted it, which is

When an app has some regular pages allocated (e.g. see below) and tries
to mmap() a huge page at a hint address covered by the same PMD entry,
the kernel accepts the hint allthough the 8xx cannot handle different
page sizes in the same PMD entry.
1000-10001000 r-xp 00:0f 2597 /root/ma
On the 8xx, we can have as many slices as PMD entries.
This means we could have 1024 slices in 4k size pages mode
and 64 slices in 16k size pages.
However, due to a stack overflow in slice_get_unmapped_area(),
we limit to 512 slices.

To correctly use EEH code one has to make
sure that the EEH_PE_VF is set for dynamic created
VFs. Therefore this patch allocates an eeh_pe of

When pseries SR-IOV is enabled and after a PF driver
has resumed from EEH, platform has to be notified
of the event so the child VFs can be allowed to
resume their normal recovery path.
This patch makes the EEH operation allow unfreeze
platform dependent code and adds the call to
pseries EEH code.
While the implementation of the "slices" address space allows
a significant amount of high slices, it limits the number of
low slices to 16 due to the use of a single u64 low_slices element
in struct slice_mask.
In order to override this limitation, this patch switches the
handling of low_slices t
Devices can go offline when erors reported. This
patch adds a change to the kernel object and lets udev

This patch series will enable SR-IOV on PowerVM. A specific set of
lids for PFW/PHYP is required. They are planned to release with
920 at the moment.
For IBM internal testers let me know of a system you want to test on
and we can put on the lids required or we can provide a system to run
the tests
When enabling SR-IOV in pseries platform,
the VF bar properties for a PF are reported on
the device node in the device tree.
This patch adds the IOV Bar resources to Linux
structures from the device tree for later use
when configuring SR-IOV by PF driver.

This is an RFC patchset to fix the call trace observed during memory
unplug for radix guests. The problem and the fix is described in patch 2/2.
The ideal fix for this is to break the bigger radix mapping into smaller
mappings during memory hot removal, but in the meanwhile I am just posting
