in r339413, a current pkgbase update problem came up. For users
testing pkgbase at the moment there is no (automatic) way to pick
up new base packages (yet).
As a result rather than also moving init(8) to its own package,
back out the part of the change in r339413 that moved rc* to its
own package and defer creating new packages until the
infrastructure is in place to handle these cases.
Both init and rc* are considered too problematic to be lost by
early adaptors at this stage.

The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.

The KPI allows to map very large contigous physical memory regions
into KVA, which are not covered by DMAP.
I see both with QEMU and with some real hardware started shipping, the
regions for NVDIMMs might be very far apart from the normal RAM, and
we expect that at least initial users of NVDIMM could install very
large amount of such memory. IMO it is not reasonable to extend DMAP
to cover that far-away regions both because it could overflow existing
4T window for DMAP in KVA, and because it costs in page table pages
allocations, for gap and for possibly unused NV RAM.
Also, KPI provides some special functionality for fast cache flushing
based on the knowledge of the NVRAM mapping use.

Device removal code uses zio_vdev_child_io() with ZIO_TYPE_NULL parent,
that never happened before. It confused FreeBSD-specific TRIM code,
which does not use VDEV_IO_DONE for logical ZIO_TYPE_FREE ZIOs. As
result of that stage being skipped device removal ZIOs leaked references
and memory that supposed to be freed by VDEV_IO_DONE, making it stuck.
It is a quick patch rather then a nice fix, but hopefully we'll be able
to drop it all together when alternative TRIM implementation finally get
landed.

- Remove the arm64-specific cpu_*cache* and cpu_tlb_flush* functions.
Instead, add RISC-V specific inline functions in cpufunc.h for the
fence.i and sfence.vma instructions.
- Catch up to changes in the arm64 pmap and remove all the cpu_dcache_*
calls, pmap_is_current, pmap_l3_valid_cacheable, and PTE_NEXT bits from
pmap.
- Remove references to the unimplemented riscv_setttb().
- Remove unused cpu_nullop.
- Add a link to the SBI doc to sbi.h.
- Add support for a 4th argument in SBI calls. It's not documented but
it seems implied for the asid argument to SBI_REMOVE_SFENCE_VMA_ASID.
- Pass the arguments from sbi_remote_sfence*() to the SEE. BBL ignores
them so this is just cosmetic.
- Flush icaches on other CPUs when they resume from kdb in case the
debugger wrote any breakpoints while the CPUs were paused in the IPI_STOP
handler.
- Add SMP vs UP versions of pmap_invalidate_* similar to amd64. The
UP versions just use simple fences. The SMP versions use the
sbi_remove_sfence*() functions to perform TLB shootdowns. Since we
don't have a valid pm_active field in the riscv pmap, just IPI all
CPUs for all invalidations for now.
- Remove an extraneous TLB flush from the end of pmap_bootstrap().
- Don't do a TLB flush when writing new mappings in pmap_enter(), only if
modifying an existing mapping. Note that for COW faults a TLB flush is
only performed after explicitly clearing the old mapping as is done in
other pmaps.
- Sync the i-cache on all harts before updating the PTE for executable
mappings in pmap_enter and pmap_enter_quick. Previously the i-cache was
only sync'd after updating the PTE in pmap_enter.
- Use sbi_remote_fence() instead of smp_rendezvous in pmap_sync_icache().

- Fix assert/panic on receive when Jumbo Frames are enabled.
From the commit I made to ixl:
"It turns out that *_isc_rxd_available is supposed to return how many
packets are available to be cleaned on the rx ring. This patch removes
a section of code where if the budget argument is 1, the function would return
one if there was a descriptor available, not necessarily a packet.
This is okay in regular mtu 1500 traffic since the max frame size is less
than the configured receive buffer size (2048), but this doesn't work when
received packets can span more than one descriptor, as is the case when the
mtu is 9000 and the receive buffer size is 4096."

From the commit by Krzysztof Galazka to ixl: "Function isc_txd_update_credits

elfcopy contained logic to filter individual relocations in STRIP_ALL
mode. However, this is not valid; relocations emitted by the linker are
required, unless they apply to an entire section being removed (which is
handled by other logic in elfcopy).
Note that filter_reloc was also buggy: for RELA relocation sections it
operated on uninitialized rel.r_info resulting in invalid operation.
The logic most likely needs to be inverted: instead of removing
relocations because their associated symbols are being removed, we must
keep symbols referenced by relocations. That said, in practice we do
not encounter this code path today: objects being stripped are either
dynamically linked binaries which retain .dynsym, or static binaries
with no relocations.
Just remove filter_reloc. This fixes certain cases including statically
linked binaries containing ifuncs. Stripping binaries with relocations
referencing removed symbols was already broken, and after this change
may still be broken in a different way.
