Commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any directory")
deprecated KBUILD_SRCTREE.
It is only used in tools/testing/selftest/ to distinguish out-of-tree
build. Replace it with a new boolean flag, building_out_of_srctree.
I also replaced the conditional ($(srctree),.) because the next commit
will allow an absolute path to be used for $(srctree) even when building
in the source tree.

We get a warning when build kernel W=1:
arch/x86/kvm/../../../virt/kvm/eventfd.c:48:1: warning: no previous prototype for ‘kvm_arch_irqfd_allowed’ [-Wmissing-prototypes]
kvm_arch_irqfd_allowed(struct kvm *kvm, struct kvm_irqfd *args)
^
The reason is kvm_arch_irqfd_allowed() is declared in arch/x86/kvm/irq.h,
which is not included by eventfd.c. Considering kvm_arch_irqfd_allowed()
is a weakly defined function in eventfd.c, remove the declaration to
kvm_host.h can fix this.

Just like we do for all other block drivers. Especially as the limit
imposed at the moment might be way to pessimistic for iommus.
This also means we are not going to set a bounce limit for the queue, in

major hold out was x86-32 with PAE, but that has been fixed by now.

As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and
MFD glue") said, these MMC controllers use the IP from Panasonic.
TMIO (Toshiba Mobile IO) MMC was the first upstreamed user of this IP.
The common driver code was split and expanded as 'tmio-mmc-core', then
it became historical misnomer since 'tmio' is not the name of this IP.
In the discussion [1], we decide to keep this name as-is at least in
Linux driver level because renaming everything is a big churn.
However, DT should not be oriented to a particular project even though
it is mainly developed in Linux communities.
This is the misfortune only in Linux. Let's stop exporting it to other
projects, where there is no good reason to call this hardware "TMIO".
Rename the file to renesas,sdhi.txt. In fact, all the information in
this file is specific to the Renesas platform.
This commit also removes the first paragraph entirely. The DT-binding
should describe the hardware. It is strange to talk about Linux driver
internals such as how the drivers are probed, how platform data are
handed off, etc.

It looks like the original idea behind always doing a re-initialization of
a removable SDIO card during system resume in mmc_sdio_resume(), is to try
to play safe to detect whether the card has been removed.
However, this seems like a really a bad idea as it will most likely screw
things up, especially when the card is expected to remain powered on during
system suspend by the SDIO func driver.
Let's fix this, simply by trusting that the detect work checks if the card
is alive and inserted, which is being scheduled at the PM_POST_SUSPEND
notification anyway.

To use the so called powered-on re-initialization of an SDIO card, the
power to the card must obviously have stayed on. If not, the initialization
will simply fail.
In the runtime suspend case, the card is always powered off. Hence, let's
drop the support for powered-on re-initialization during runtime resume, as
it doesn't make sense.
Moreover, during a HW reset, the point is to cut the power to the card and
then do fresh re-initialization. Therefore drop the support for powered-on
re-initialization during HW reset.

In some cases, using the 'truncate' command to extend a UDF file results
in a mismatch between the length of the file's extents (specifically, due
to incorrect length of the final NOT_ALLOCATED extent) and the information
(file) length. The discrepancy can prevent other operating systems
(i.e., Windows 10) from opening the file.
Two particular errors have been observed when extending a file:
1. The final extent is larger than it should be, having been rounded up
to a multiple of the block size.
B. The final extent is not shorter than it should be, due to not having
been updated when the file's information length was increased.

netfilter: add hardware offload infrastructure
This patchset adds support for Netfilter hardware offloads.
This patchset reuses the existing block infrastructure, the
netdev_ops->ndo_setup_tc() interface, TC_SETUP_CLSFLOWER classifier and
the flow rule API.
Patch #1 adds flow_block_cb_setup_simple(), most drivers do the same thing
to set up flow blocks, to reduce the number of changes, consolidate
codebase. Use _simple() postfix as requested by Jakub Kicinski.
This new function resides in net/core/flow_offload.c
Patch #2 renames TC_BLOCK_{UN}BIND to FLOW_BLOCK_{UN}BIND.
Patch #3 renames TCF_BLOCK_BINDER_TYPE_* to FLOW_BLOCK_BINDER_TYPE_*.
Patch #4 adds flow_block_cb_alloc() and flow_block_cb_free() helper
functions, this is the first patch of the flow block API.
Patch #5 adds the helper to deal with list operations in the flow block API.
This includes flow_block_cb_lookup(), flow_block_cb_add() and
flow_block_cb_remove().
Patch #6 adds flow_block_cb_priv(), flow_block_cb_incref() and
flow_block_cb_decref() which completes the flow block API.
Patch #7 updates the cls_api to use the flow block API from the new
tcf_block_setup(). This infrastructure transports these objects
via list (through the tc_block_offload object) back to the core
for registration.
CLS_API DRIVER
TC_SETUP_BLOCK ----------> setup flow_block_cb object &
it adds object to flow_block_offload->cb_list
|
CLS_API <-----------------------'
registers list with flow blocks
flow_block_cb & travels back to
calls ->reoffload the core for registration
drivers allocate and sets up (configure the blocks), then
registration happens from the core (cls_api and netfilter).
Patch #8 updates drivers to use the flow block API.
Patch #9 removes the tcf block callback API, which is replaced by the
flow block API.
Patch #10 adds the flow_block_cb_is_busy() helper to check if the block
is already used by a subsystem. This helper is invoked from
drivers. Once drivers are updated to support for multiple
subsystems, they can remove this check.
Patch #11 rename tc structure and definitions for the block bind/unbind
path.
Patch #12 introduces basic netfilter hardware offload infrastructure
for the ingress chain. This includes 5-tuple exact matching
and accept / drop rule actions. Only basechains are supported
at this stage, no .reoffload callback is implemented either.
Default policy to "accept" is only supported for now.
table netdev filter {
chain ingress {
type filter hook ingress device eth0 priority 0; flags offload;
ip daddr 192.168.0.10 tcp dport 22 drop
}
}
This patchset reuses the existing tcf block callback API and it places it
in the flow block callback API in net/core/flow_offload.c.
This series aims to address Jakub and Jiri's feedback, please see specific
patches in this batch for changelog in this v4.

This patch adds hardware offload support for nftables through the
existing netdev_ops->ndo_setup_tc() interface, the TC_SETUP_CLSFLOWER
classifier and the flow rule API. This hardware offload support is
available for the NFPROTO_NETDEV family and the ingress hook.
Each nftables expression has a new ->offload interface, that is used to
populate the flow rule object that is attached to the transaction
object.
There is a new per-table NFT_TABLE_F_HW flag, that is set on to offload
an entire table, including all of its chains.
This patch supports for basic metadata (layer 3 and 4 protocol numbers),
5-tuple payload matching and the accept/drop actions; this also includes
basechain hardware offload only.
