f69261f2f9 Fix fcntl(2) compat32 after r270691. The copyin and copyout of the
struct flock are done in the sys_fcntl(), which mean that compat32 used
direct access to userland pointers.

Move code from sys_fcntl() to new wrapper, kern_fcntl_freebsd(), which
performs neccessary userland memory accesses, and use it from both
native and compat32 fcntl syscalls.

2c6fbcbed6 In kern_linkat() and kern_renameat(), do not call namei(9) while
holding a write reference on the filesystem.  Try to get write
reference in unblocked way after all vnodes are resolved; if failed,
drop all locks and retry after waiting for suspension end.

The VFS_UNMOUNT() methods for UFS and tmpfs try to establish
suspension on unmount, while covered vnode is locked by VFS, which
prevents namei() from stepping over the mount point.  The thread doing
namei() sleeps on the covered vnode lock, owning the write ref.

c47d4cde39 Replace multiple nearly-identical copies of code to walk through an FDT
node's interrupts=<...> property creating resource list entries with a
single common implementation.  This change makes ofw_bus_intr_to_rl() the
one true copy of that code and removes the copies of it from other places.

This also adds handling of the interrupts-extended property, which allows
specifying multiple interrupts for a node where each interrupt can have a
separate interrupt-parent.  The bindings for this state that the property
cells contain an xref phandle to the interrupt parent followed by whatever
interrupt info that parent normally expects.  This leads to having a
variable number of icells per interrupt in the property.  For example you
could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>.

c98a2727cc ddb: allow specifying the exact address of the symtab and strtab
When the FreeBSD kernel is loaded from Xen the symtab and strtab are
not loaded the same way as the native boot loader. This patch adds
three new global variables to ddb that can be used to specify the
exact position and size of those tables, so they can be directly used
as parameters to db_add_symbol_table. A new helper is introduced, so callers
that used to set ksym_start and ksym_end can use this helper to set the new
variables.

It also adds support for loading them from the Xen PVH port, that was
previously missing those tables.

ddb/db_main.c:
 - Add three new global variables: ksymtab, kstrtab, ksymtab_size that
   can be used to specify the position and size of the symtab and
   strtab.
 - Use those new variables in db_init in order to call db_add_symbol_table.
 - Move the logic in db_init to db_fetch_symtab in order to set ksymtab,
   kstrtab, ksymtab_size from ksym_start and ksym_end.

ddb/ddb.h:
 - Add prototype for db_fetch_ksymtab.
 - Declate the extern variables ksymtab, kstrtab and ksymtab_size.

x86/xen/pv.c:
 - Add support for finding the symtab and strtab when booted as a Xen
   PVH guest. Since Xen loads the symtab and strtab as NetBSD expects
   to find them we have to adapt and use the same method.

8d864935b6 Run through unifdef(1) with slight hand-editing after. It is obvious,
that the driver is not going to be ever improved in terms of hardware
support, it is going to be only maintained as our kernel APIs change.
Carrying all the compatibility with ancient versions of NetBSD, OpenBSD,
Linux and BSDI, as well as obsoleted FreeBSD versions has no reason.

54432196db vm_map_pmap_enter() and pmap_enter_object() are currently not aware of
the wired attribute of the mapping.  As result, some pmap
implementations clear the wired state of the page table entries, which
breaks invariants and allows the entries to be lost.  Avoid calling
vm_map_pmap_enter() for the MADV_WILLNEED on the wired entry, the
pages must be already mapped.

14f2533c56 As per [1] Intel only supports this driver on 64bit platforms.
For now restrict it to amd64.  Other architectures might be
re-added later once tested.

Remove the drivers from the global NOTES and files files and move
them to the amd64 specifics.
Remove the drivers from the i386 modules build and only leave the
amd64 version.

Rather than depending on "inet" depend on "pci" and make sure that
ixl(4) and ixlv(4) can be compiled independently [2].  This also
allows the drivers to build properly on IPv4-only or IPv6-only
kernels.
