The Hyper-V on pre-win10 systems will only report SPC-2 conformance,
but it actually conforms to SPC-3. The INQUIRY response is adjusted
to propagate the SPC-3 version information to CAM.

Add -sac (space after cast) and -nsac options.
These control whether space character is put after a cast operator or not.
Default is -nsac.
Add -U option for providing a file containing list of types.
This is needed for properly deciding which asterisks denote unary
operation and which denote binary.
These come from PostgreSQL.

On Zynq 256K-512K memory region is not accessible by all bus masters.
EHCI driver fails when trying to use it for DMA transfers. Patching
memory node does not help because ubldr overrides values there with
the ones obtained from u-boot. So as a workaround we just mark first
512K as reserved.

Chelsio T4/T5 adapters are multifunction cards. The main driver uses
physical function 4 (PF4). However, VF devices for SR-IOV are only
supported on physical functions 0 through 3, where PF0 creates VFs tied
to port 0, etc. The t4iov/t5iov driver was previously added to
create VF devices for ports that are present on each adapter. This
change uses the recently added pci_iov_attach_name() function to
name the character device in /dev/iov after the associated port on
the card (e.g. /dev/iov/cxl0 is used to create VFs that share the
cxl0 port). With this in place, mark the t4iov/t5iov devices quiet
to prevent them from cluttering dmesg.

The PCI_IOV option creates character devices in /dev/iov for each PF
device driver that registers support for creating VFs. By default the
character device is named after the PF device (e.g. /dev/iov/foo0).
This change adds a variant of pci_iov_attach() called pci_iov_attach_name()
that allows the name of the /dev/iov entry to be specified by the
driver.

two sepatate functions to make glob(3) code less obscure and more simple.
There is no needs to make them inline since it is error path which supposed
to not happes often.
Owning Giant in the init/uninit is accidental due to the moment where
VFS modules initialization is performed, and is not enforced by the
VFS interface. The Giant lock does not prevent a parallel execution
of the code, it is VFS which implements the proper protocol.

Our mprotect() function seems to take a "const void *" address to the
pages whose permissions need to be adjusted. POSIX uses "void *". Simply
stick to the POSIX one to prevent us from writing unportable code.

CPU number for MPC85XX is a duplicate for E500. Since we don't support MPC85XX
"uncore" registers right now, rather than renumbering it simply remove it, and
it will properly use the E500 CPU ID.
Summary:
MPC85XX and QorIQ are very similar. When the DPAA dTSEC driver was
added, QORIQ_DPAA was brought in as a config option to support the differences
in hardware register settings between QorIQ (e500mc-, e5500- based) SoCs and
QUICC (e500v1/e500v2-based) SoCs, particularly in the Local Access Window (LAW)
target settings.
Unify these settings using macros to hide details and ease porting, and use a
new function (mpc85xx_is_qoriq()) to distinguish between QorIQ and QUICC SoCs at
runtime.
An alternative to using the function could be to use a variable initialized at
platform attach time, which may incur less overhead at runtime. Since it's not
in the critical path once booted, this optimization doesn't seem necessary at
first pass.

we need to include it in -legacy or not. Since the ifdef was removed,
this broke building 10.x and older source trees on -current. Restore
just enough of _WITH_GETLINE to allow these older source trees to
still build and properly omit getline() from their -legacy library.
kgzip is only useful on i386 and has a number of other limitations.

or "+" (these are invalid, because there is no preceding operand).
When bsdgrep attempts to emulate GNU grep in discarding and ignoring the
invalid ? or + operators, some later logic in tre_compile_fast() goes
beyond the end of the buffer, leading to a crash.
Fix this by bailing out, and reporting a bad pattern instead.
