Allocate per-VPE SGIs when initializing the GIC-specific part of the

In order to hide some of the differences between v4.0 and v4.1, move
the doorbell management out of the KVM code, and into the GICv4-specific
layer. This allows the calling code to ask for the doorbell when blocking,
and otherwise to leave the doorbell permanently disabled.
This matches the v4.1 code perfectly, and only results in a minor
refactoring of the v4.0 code.

In order to let a guest buy in the new, active-less SGIs, we
need to be able to switch between the two modes.
Handle this by stopping all guest activity, transfer the state
from one mode to the other, and resume the guest. Nothing calls
this code so far, but a later patch will plug it into the MMIO
emulation.

Just like for vLPIs, there is some configuration information that cannot
be directly communicated through the normal irqchip API, and we have to
use our good old friend set_vcpu_affinity as a side-band communication
mechanism.
This is used to configure group and priority for a given vSGI.

To implement the get/set_irqchip_state callbacks (limited to the
PENDING state), we have to use a particular set of hacks:
- Reading the pending state is done by using a pair of new redistributor
registers (GICR_VSGIR, GICR_VSGIPENDR), which allow the 16 interrupts
state to be retrieved.
- Setting the pending state is done by generating it as we'd otherwise do
for a guest (writing to GITS_SGIR).
- Clearing the pending state is done by emitting a VSGI command with the
"clear" bit set.
This requires some interesting locking though:
- When talking to the redistributor, we must make sure that the VPE
affinity doesn't change, hence taking the VPE lock.
- At the same time, we must ensure that nobody accesses the same
redistributor's GICR_VSGIR registers for a different VPE, which
would corrupt the reading of the pending bits. We thus take the
per-RD spinlock. Much fun.

The GICv4.1 ITS has yet another new command (VSGI) which allows
a VPE-targeted SGI to be configured (or have its pending state
cleared). Add support for this command and plumb it into the
activate irqdomain callback so that it is ready to be used.

Since GICv4.1 has the capability to inject 16 SGIs into each VPE,
and that I'm keen not to invent too many specific interfaces to
manipulate these interrupts, let's pretend that each of these SGIs
is an actual Linux interrupt.
For that matter, let's introduce a minimal irqchip and irqdomain
setup that will get fleshed up in the following patches.

Since commit "drivers: provide devm_platform_ioremap_resource()",
it was wrap platform_get_resource() and devm_ioremap_resource() as
single helper devm_platform_ioremap_resource(). but now, many drivers
still used platform_get_resource() and devm_ioremap_resource()
together in the kernel tree. The reason can not be replaced is they
still need use the resource variables obtained by platform_get_resource().
so provide this helper.

Packet trap groups are now explicitly registered by drivers and not
implicitly registered when the packet traps are registered. Therefore,
there is no need to encode entire group structure the trap is associated
with inside the trap structure.
Instead, only pass the group identifier. Refer to it as initial group
identifier, as future patches will allow user space to move traps
between groups.

Currently, packet trap groups are implicitly registered by drivers upon
packet trap registration. When the traps are registered, each is
associated with a group and the group is created by devlink, if it does
not exist already.
This makes it difficult for drivers to pass additional attributes for
the groups.
Therefore, as a preparation for future patches that require passing
additional group attributes, add an API to explicitly register /
unregister these groups.
Next patches will convert existing drivers to use this API.

100GbE Intel Wired LAN Driver Updates 2020-03-21
Implement basic support for the devlink interface in the ice driver.
Additionally pave some necessary changes for adding a devlink region that
exposes the NVM contents.
This series first contains 5 patches for enabling and implementing full NVM
read access via the ETHTOOL_GEEPROM interface. This includes some cleanup of
endian-types, a new function for reading from the NVM and Shadow RAM as a flat
addressable space, a function to calculate the available flash size during
load, and a change to how some of the NVM version fields are stored in the
ice_nvm_info structure.
Following this is 3 patches for implementing devlink support. First, one patch
which implements the basic framework and introduces the ice_devlink.c file.
Second, a patch to implement basic .info_get support. Finally, a patch which
reads the device PBA identifier and reports it as the `board.id` value in the
.info_get response.

nl_set_extack_cookie_u32() helpers do not check extack argument for null
and neither do their callers, as syzbot recently discovered for

This ioctl will be responsible for deleting a subvolume using its id.
This can be used when a system has a file system mounted from a
subvolume, rather than the root file system, like below:
/
@subvol1/
@subvol2/
@subvol_default/
If only @subvol_default is mounted, we have no path to reach @subvol1
and @subvol2, thus no way to delete them. Current subvolume delete ioctl
takes a file handle point as argument, and if @subvol_default is
mounted, we can't reach @subvol1 and @subvol2 from the same mount point.
This patch introduces a new ioctl BTRFS_IOC_SNAP_DESTROY_V2 that takes
the extended structure with flags to allow to delete subvolume using
subvolid.
Now, we can use this new ioctl specifying the subvolume id and refer to
the same mount point. It doesn't matter which subvolume was mounted,
since we can reach to the desired one using the subvolume id, and then
delete it.
The full path to the subvolume id is resolved internally and access is
verified as if the subvolume was accessed by path.
The volume args v2 structure is extended to use the existing union for
subvolume id specification, that's valid in case the
BTRFS_SUBVOL_SPEC_BY_ID is set.

Make it so that CEPH_MSG_DATA_PAGES data item can own pages,
fixing a bunch of memory leaks for a page vector allocated in
alloc_msg_with_page_vector(). Currently, only watch-notify
messages trigger this allocation, and normally the page vector
is freed either in handle_watch_notify() or by the caller of
ceph_osdc_notify(). But if the message is freed before that
(e.g. if the session faults while reading in the message or
if the notify is stale), we leak the page vector.
This was supposed to be fixed by switching to a message-owned
pagelist, but that never happened.
