Patches with very little context (-U0 and -U1) could get misapplied if
the file to be patched changes and a hunk is no longer applicable. Matching
with fuzz would be attempted and default to a match when we unexpectedly ran

to maintain absolute alignment, TLS TCB should by also aligned.

If _mapping_process_dpm_pg0 detects inconsistencies in the drive
mapping table (stored in the HBA's NVRAM), abort reading it and
continue to boot as if the mapping table were blank. I observed
such inconsistencies in several HBAs after upgrading firmware from
14.0.0.0 to 15.0.0.0.

instead of malloc(). The SWAP objects are automagically freed when there are no
more consumers. This greatly simplifies the mmap logic inside CUSE(3) in the
kernel. This change fixes an issue where mmapped memory can accumulate and never
get freed, if many different mmap sizes are needed over time. Further this
change fixes memory leaks when the CUSE(3) kernel module is unloaded.
While at it make sure the CUSE_ALLOC_PAGES_MAX limit is treated as an exclusive
limit. CUSE(3) memory maps must be less than CUSE_ALLOC_PAGES_MAX number of pages.

This pointer is checked during the linux_dev_open() callback and does
not need to be NULL checked again. It should always be set for
character devices belonging to the "linuxcdevsw" and technically
there is no need to NULL check this pointer at all.

When trying to build world for MIPS64 with clang I was getting

It turns out std::get_new_handler() was not listed in Version.map so it was

fine when a lot of different flows to be ciphered/deciphered are involved.
However, when a software crypto driver is used, there are
situations where we could benefit from making crypto(9) multi threaded:
- a single flow is to be ciphered: only one thread is used to cipher it,
- a single ESP flow is to be deciphered: only one thread is used to
decipher it.
The idea here is to call crypto(9) using a new mode (CRYPTO_F_ASYNC) to
dispatch the crypto jobs on multiple threads, if the underlying crypto
driver is working in synchronous mode.
Another flag is added (CRYPTO_F_ASYNC_KEEPORDER) to make crypto(9)
dispatch the crypto jobs in the order they are received (an additional
queue/thread is used), so that the packets are reinjected in the network
using the same order they were posted.
A new sysctl net.inet.ipsec.async_crypto can be used to activate
this new behavior (disabled by default).

gcc complains "cast to pointer from integer of different size". phandle_t is
*always* a uint32_t, so treat it as such, not as a pointer. Fixes 64-bit build.
This is to prevent downstream checks from assuming they can trust .OBJDIR when
MK_AUTO_OBJ is yes, such as the bsd.obj.mk checks.

This still keeps the reduced MAKEOBJDIRPREFIX (SRCTOP) redundancy
removed in the OBJDIR, but now keeps all early phase objects
in the same directory rather than split per phase.
The problem of splitting per phase is that later phases want to link in
libraries from earlier phases and base their location on ${OBJTOP}.

This will force any existing objects to rebuild if their .meta
files reference files from WORLDTMP. This is a problem after
the UNIFIED_OBJDIR effort caused buildworld and DIRDEPS_BUILD
to share an OBJDIR. Without cleaning these files the
Makefile.depend files end up with odd tmp/legacy/... entries
since some bootstrap-tools linger from there and otherwise
don't rebuild. Removing the files causes anything having
used WORLDTMP to rebuild.

This can be disabled by putting WITHOUT_AUTO_OBJ=yes in /etc/src-env.conf, not
/etc/src.conf, or passing it in the environment.
The purpose of this rather than simply flipping the default of AUTO_OBJ to yes
is to avoid hassling users with auto.obj.mk failures if the wanted OBJDIR is
not writable. It will fallback to writing to the source directory like it does
today if MAKEOBJDIRPREFIX is not writable.
The act of enabling MK_AUTO_OBJ disables all 'make obj' treewalks since
previous work has made those not run if MK_AUTO_OBJ==yes in Makefile.inc1.

emulation in fast path of data/prefetch abort common routine. Process
these bits only if related page table entries are consistent with
provided abort info. In case of inconsistency, do nothing and let
processor to signal new abort if still needed.
The mapping related to an abort may be a subject of change concurrently.
The situation is more evident on multicore machines. Mapping may be
removed on one core while being used on another one before TLB flush
happened. Memory swapping process may be an example. Or, two or more
aborts may be signaled for the same page on more cores concurrently.
While an abort on one core may cause a promotion of related mapping,
an abort on another core may be inconsistent then as related mapping
was promoted. A question is how much real the issue may be on single
core machine. However, it's better to play safe even for these machines.
This change may solve some "PT2MAP abort" panics reported rarely.
The revision of pmap_fault() was initiated thanks to stack backtrace
provided by Bob Prohaska (fbsd at www.zefox.net).
While here, INVARIANTS block was changed. The previous check had iffy
value as only one entry from many was checked from L2 page table.

The generic (naive) implementation of posix_fallocate cannot provide the
standard mandated guarantee that overwrites would never fail due to the lack
of free space. The fundamental reason is the copy-on-write architecture
of ZFS. Other features like compression and deduplication can also
increase the size difference between the (pre-)allocated dummy content
and the future content.
So, until ZFS can properly implement the feature it's better to report
that it is unsupported rather than providing an ersatz implementation.
Please note that EINVAL is used to report that the underlying file system
does not support the operation (POSIX.1-2008).
illumos and ZoL seem to do the same.
