We've now implemented code in the pseries platform to use the new PAPR
interface to allow resizing the hash page table (HPT) at runtime.
This patch uses that interface to automatically attempt to resize the HPT
when memory is hot added or removed. This tries to always keep the HPT at
a reasonable
The hypervisor needs to know a guest is capable of using the HPT resizing
PAPR extension in order to make full advantage of it for memory hotplug.
If the hypervisor knows the guest is HPT resize aware, it can size the
initial HPT based on the initial guest RAM size, relying on the guest to
resize
This adds the hypercall numbers and wrapper functions for the hash page
table resizing hypercalls.
These are experimental "platform specific" values for now, until we have a
formal PAPR update.
It also adds a new firmware feature flag to track the presence of the
HPT resizing calls.

This adds support for using experimental hypercalls to change the size

hypercalls are only in experimental qemu versions.

At present KVM on powerpc always reports KVM_CAP_PPC_ALLOC_HTAB as enabled.
However, the ioctl() it advertises (KVM_PPC_ALLOCATE_HTAB) only actually

qemu already has a workaround for this, so it's not breaking things in

This series implements the guest side of a PAPR ACR which allows a
POWER guest's Hashed Page Table (HPT) to be resized at runtime. This
is useful when a guest has a very large theoretical maximum RAM, but
is likely to only ever be expanded to a modest amount of RAM in
practice. Without resizing t
The KVM_PPC_PVINFO_FLAGS_EV_IDLE macro defines a bit for use in the flags

In commit a4b349540a26af ("powerpc/mm: Cleanup LPCR defines") we updated
LPCR_VRMASD wrongly as below.
-#define LPCR_VRMASD (0x1ful << (63-16))
+#define LPCR_VRMASD_SH 47
+#define LPCR_VRMASD (ASM_CONST(1) << LPCR_VRMASD_SH)
We initialize the VRMA bits in LPCR to 0x00 in kvm

The first byte of each CRQ entry is used to indicate whether an entry is
a valid response or free for the VIOS to use. After processing a

An unrecogonized or unsupported SRP response has its opcode currently
logged in decimal format. Log it in hex format instead so it can easily
be validated against the SRP specs values which are in hex.

This patch add support to return value from host_init() callback from drivers,
so that the designware libary can handle or pass it to proper place. Issue with
