While attempting to upstream a patch to add the IDIV hwcap for
Krait processors, Will suggested we move the code to read the

the early Krait CPU designs that don't follow the latest ARM ARM

The ISAR0 register indicates support for the SDIV and UDIV

Support 2M page allocations when memory is ballooned out of the
guest. Hyper-V Dynamic Memory protocol is optimized around the ability
to move memory in 2M chunks.
I have also included a patch to properly notify the host of permanent
hot-add failures.
In this version of the patches, I have added
This symbol would be used in the Hyper-V balloon driver to support 2M

If memory hot-add fails with the error -EEXIST, then this is a permanent
failure. Notify the host of this information, so the host will not attempt
hot-add again. If the failure were a transient failure, host will attempt
a hot-add after some delay.
In this version of the patch, I have added some
On Hyper-V it will be very efficient to use 2M allocations in the guest as this
makes the ballooning protocol with the host that much more efficient. Hyper-V
uses page ranges (start pfn : number of pages) to specify memory being moved
around and with 2M pages this encoding can be very efficient.

Hello!
This series contains the following changes to RCU documentation:
1. Make the bugginess of a code sample more apparent with
all-caps comments.
2. RCU documentation update based on review motivated by the
first commit.
From: Paul E. McKenney paul...@linux.vnet.ibm.com
This commit applies a few updates based on a quick review of the RCU
documentations.

One of the code samples in whatisRCU.txt shows a bug, but someone scanning
the document quickly might mistake it for a valid use of RCU. Add some
screaming comments to help keep speed-readers on track.
