architecture: Add support for the RISC-V architecture. (#4305)
RISC-V is an open source ISA in development since 2010 at UCB.
For more information, see https://riscv.org/
I am adding RISC-V support to Fedora:
https://fedoraproject.org/wiki/Architectures/RISC-V
There are three major variants of the architecture (32-, 64- and
128-bit). The 128-bit variant is a paper exercise, but the other
two really exist in silicon. RISC-V is always little endian.
On Linux, the default kernel uname(2) can return "riscv" for all
variants. However a patch was added recently which makes the kernel
return one of "riscv32" or "riscv64" (or in future "riscv128"). So
systemd should be prepared to handle any of "riscv", "riscv32" or
"riscv64" (in future, "riscv128" but that is not included in the
current patch). If the kernel returns "riscv" then you need to use
the pointer size in order to know the real variant.
The Fedora/RISC-V kernel only ever returns "riscv64" since we're
only doing Fedora for 64 bit at the moment, and we've patched the
kernel so it doesn't return "riscv".
As well as the major bitsize variants, there are also architecture
extensions. However I'm trying to ensure that uname(2) does *not*
return any other information about those in utsname.machine, so that
we don't end up with "riscv64abcde" nonsense. Instead those
extensions will be exposed in /proc/cpuinfo similar to how flags
work in x86.

DNS servers which have route-only domains should only be used for

violation, prone to fail (as that DNS server was not meant to be used for other

Introduce a new helper function dns_server_limited_domains() that checks if the
DNS server should only be used for some selected domains, i. e. has some
route-only domains without "~.". Use that when determining whether to query it
in the scope, and when writing resolv.conf.
Extend the test_route_only_dns() case to ensure that the DNS server limited to
~company does not appear in resolv.conf. Add test_route_only_dns_all_domains()

coredump: remove Storage=both option
Back when external storage was initially added in
34c10968cb, this mode of
storage was added. This could have made some sense back when XZ compression was
used, and an uncompressed core on disk could be used as short-lived cache file
which does require costly decompression. But now fast LZ4 compression is used
(by default) both internally and externally, so we have duplicated storage,
using the same compression and same default maximum core size in both cases,
but with different expiration lifetimes. Even the uncompressed-external,
compressed-internal mode is not very useful: for small files, decompression
with LZ4 is fast enough not to matter, and for large files, decompression is
still relatively fast, but the disk-usage penalty is very big.
An additional problem with the two modes of storage is that it complicates
the code and makes it much harder to return a useful error message to the user
if we cannot find the core file, since if we cannot find the file we have to
check the internal storage first.
This patch drops "both" storage mode. Effectively this means that if somebody
configured coredump this way, they will get a warning about an unsupported
value for Storage, and the default of "external" will be used.
I'm pretty sure that this mode is very rarely used anyway.

If ulimit is smaller than page_size(), function save_external_coredump()
