9426 metaslab size can exceed offset addressable by spacemap
metaslab size can exceed offset addressable by spacemap. The vdev can
address up to 2^63 * SPA_MAXBLOCKSIZE (512). A metaslab can address up to
2^47 * 2^vdev_ashift. Therefore we may need to increase the number of
metaslabs so that the maximum metaslab size is capped at the amount that
can be addressed by the spacemap. This should happen in
vdev_metaslab_set_size().

9403 assertion failed in arc_buf_destroy() when concurrently reading block with checksum error
This assertion (VERIFY) failure was reported when reading a block. Turns out
the problem is that if we get an i/o error (ECKSUM in this case), and there
are multiple concurrent ARC reads of the same block (from different clones),
then the ARC will put multiple buf's on the same ANON hdr, which isn't
supposed to happen, and then causes a panic when we try to arc_buf_destroy()
the buf.

9102 zfs should be able to initialize storage devices
The first access to a disk block can incur a performance penalty on some
platforms (e.g. AWS's EBS, VMware VMDKs). Therefore it is recommended that
volumes be "thick provisioned", where supported by the platform (VMware).
Thick provisioning is time consuming and often is ignored. If the thick
provision step is omitted, customers will see suboptimal performance until
we have written to all parts of the LUN. ZFS should be able to initialize
any unused storage to remove any first-write penalty that exists.

Such situations are increasingly common with jemalloc >= 5.0. This
change has the expected effect of reducing the number of vm map entry and

The Tag_ABI_VFP_args build attribute controls the procedure call
standard used for floating point parameters on ARM. The values are:
0 - Base AAPCS (FP Parameters passed in Core (Integer) registers
1 - VFP AAPCS (FP Parameters passed in FP registers)
2 - Toolchain specific (Neither Base or VFP)
3 - Compatible with all (No use of floating point parameters)
If the Tag_ABI_VFP_args build attribute is missing it has an implicit
value of 0.
We use the attribute in two ways:
* Detect a clash in calling convention between Base, VFP and Toolchain.
we follow ld.bfd's lead and do not error if there is a clash between an
implicit Base AAPCS caused by a missing attribute. Many projects
including the hard-float (VFP AAPCS) version of glibc contain assembler
files that do not use floating point but do not have Tag_ABI_VFP_args.
* Set the EF_ARM_ABI_FLOAT_SOFT or EF_ARM_ABI_FLOAT_HARD ELF header flag
for Base or VFP AAPCS respectively. This flag is used by some ELF
loaders.
References:
* Addenda to, and Errata in, the ABI for the ARM Architecture for
Tag_ABI_VFP_args

The LLD implementation of Tag_ABI_VFP_args needs to check the rarely
seen values of 3 (toolchain specific) and 4 compatible with both Base
and VFP. Add the missing enumeration values so that LLD can refer to
them without having to use the raw numbers.
Obtained from: llvm r338373 by Peter Smith
The ELF for the Arm architecture document defines, for EF_ARM_EABI_VER5
and above, the flags EF_ARM_ABI_FLOAT_HARD and EF_ARM_ABI_FLOAT_SOFT.
These have been defined to be compatible with the existing
EF_ARM_VFP_FLOAT and EF_ARM_SOFT_FLOAT used by gcc for
EF_ARM_EABI_UNKNOWN.
This patch adds the flags in addition to the existing ones so that any
code depending on the old names will still work.

This calls into the Arm Trusted Firmware to enable and disable the

As this may have a large performance overhead, and how exploitable SSBD is

between always on, always off, or only enabled in the kernel, with the
latter being the default.
