r329190; sparc64 kernels are always 64-bit but with that revision
in place, the loader was treating them as 32-bit ones.
- In order to reduce the likelihood of this kind of breakage in the
future, #ifdef out md_load() on sparc64 and make md_load_dual() -
which is currently local to metadata.c anyway - static.
- Make md_getboothowto() - also local to metadata.c - static.
- Get rid of the unused DTB pointer on sparc64.
This changes previous behavior of calculating it at startup based on
the current max username length.
This is done because:
- it is in theory possible for the max length to change at run-time
(e.g., a new user is added after top starts running)
- on machines with many users this delays startup significantly

POSIX requires accepting unquoted newlines in word in parameter expansions
like ${param+word}, ${param#word}, although the Bourne shell did not support
it, it is not commonly used and might make it harder to find a missing
closing brace.
It was also strange that something like
foo="${bar#
}"
was rejected.

The escape sequence (e.g. `^[[2 q`) was unsupported before and the
letter `q` was displayed as a typed character. The sequence is used by
Neovim for instance.
Now, it is properly parsed. However, it is ignored, so it won't change
the cursor style.
Because the escape sequence contains a space character, the
`gensequences` script had to be modified to support that. In the
`sequences` file, a space is represented as the string `SP`.
Merge the latest file(1) in.
Relevent Changelog:
- extend the support for ${x?:} expansions for magic descriptions
- add support for ${x?:} in mime types to handle pie binaries.
- add support for negative offsets (offsets from the end of file)
- close the file on error when writing magic
Relnotes: yes
The interlock pointer is non-NULL by definition and the compiler see through
that and eliminates the NULL checks. Just remove them from the code as they
play no role.
No difference in generated assembly.
in_pcbfree will remove the incpb from the list and release the rtentry
while the vnet is set, but the actual destruction will be deferred
until any threads in a (not yet used) epoch section, no longer potentially
have references.
Summary:
POWER9 systems use a new interrupt controller, XIVE, managed through OPAL
firmware calls. The OPAL firmware includes support for emulating the previous
generation XICS presentation layer in addition to a new "XIVE Exploitation"
mode. As a stopgap until we have XIVE exploitation mode, enable XICS emulation
mode so that we at least have an interrupt controller.
Since the CPPR is local to the current CPU, it cannot be updated for APs when
initializing on the BSP. This adds a new function, directly called by the
powernv platform code, to initialize the CPPR on AP bringup.
