d7a7e17968 Remove explicit calling of lockmgr() with the NULL argument.
Now, lockmgr() function can only be called passing curthread and the
KASSERT() is upgraded according with this.

In order to support on-the-fly owner switching, the new function
lockmgr_disown() has been introduced and gets used in BUF_KERNPROC().
KPI, so, results changed and FreeBSD version will be bumped soon.
Differently from previous code, we assume idle thread cannot try to
acquire the lockmgr as it cannot sleep, so loose the relative check[1]
in BUF_KERNPROC().

Tested by: kris

[1] kib asked for a KASSERT in the lockmgr_disown() about this
condition, but after thinking at it, as this is a well known general
rule, I found it not really necessary.

e46502943a Make ftruncate a 'struct file' operation rather than a vnode operation.
This makes it possible to support ftruncate() on non-vnode file types in
the future.
- 'struct fileops' grows a 'fo_truncate' method to handle an ftruncate() on
  a given file descriptor.
- ftruncate() moves to kern/sys_generic.c and now just fetches a file
  object and invokes fo_truncate().
- The vnode-specific portions of ftruncate() move to vn_truncate() in
  vfs_vnops.c which implements fo_truncate() for vnode file types.
- Non-vnode file types return EINVAL in their fo_truncate() method.

24ecb0cb15 If the disk reports that it support the Compact Flash Association command
set, announce BIO_DELETE capability and issue ATA_CFA_ERASE when we get one.

Once we issue more BIO_DELETE, this will improve lifetime, and
possibly write speed of Flash based devices which have usable flash
adaptation layers.

For now, about the only usage is the newfs(1) -E flag.

08d2425f6f Follow the current fashion of gratuitously stomping into other
peoples code with irrelevant changes[1]:

Use bus_{read|write_*() instead of bus_space_{read|write}_*() for
purely stylistic reasons.

Due to compiler optimizations and inlining, this is for all practical
purposes without effect in the compiled code.

b6ae6984e8 Don't duplicate the whole of arpresolve to arpresolve 2 for the sake
of two compares against 0. The negative effect of cache flushing
is probably more than the gain by not doing the two compares (the
value is almost certainly in register or at worst, cache).
Note that the uses of m_freem() are in error cases and m_freem()
handles NULL anyhow. So fast-path really isn't changed much at all.

397c19d175 Remove explicit locking of struct file.
- Introduce a finit() which is used to initailize the fields of struct file
   in such a way that the ops vector is only valid after the data, type,
   and flags are valid.
 - Protect f_flag and f_count with atomic operations.
 - Remove the global list of all files and associated accounting.
 - Rewrite the unp garbage collection such that it no longer requires
   the global list of all files and instead uses a list of all unp sockets.
 - Mark sockets in the accept queue so we don't incorrectly gc them.

d2d9ab366b Correct the comments in am7990_intr() and am79900_intr(); it's not
possible to end up in the interrupt handler again while processing the
previous RX interrupt in ifp->if_input() because the MD interrupt code
disables the delivery of the respective interrupt until all associated
handlers were called (in the INTR_FILTER case the MI code supposedly
does the same). Toggling the NIC interrupt enable bit in these handlers
still is necessary though as some chips (f.e. the VMware emulated one)
require this to be done in order to keep issuing interrupts.

9336e0699b Replace explicit calls to video methods with their respective variants
implemented with macros. This patch improves code readability. Reasoning
behind vidd_* is a sort of "video discipline".

List of macros is supposed to be complete--all methods of video_switch
ought to have their respective macros from now on.

Functionally, this code should be no-op. My intention is to leave current

c5860546c4 Fix some bugs in the FreeBSD 4/5/6 pci(4) IOCTLs compatibility code:
- Use the correct offsets when copying out the results of PCIOCGETCONF_OLD.
  This happened to not affect the 64-bit architectures because there the
  addition of pc_domain to struct pcisel didn't change the overall size of
  struct pci_conf. [1]
- Always copy the name and unit information to conf_old so it's also part
  of the output once this information is cached in dinfo.
- Use the correct type for flags in struct pci_match_conf_old. This
  change is more or less cosmetic though.

316d90a37b Move the check for the snp device being already attached after the
fget() call, that is sleeping point, and possibly dropping Giant.

The snp_target == NULL implies the snp_tty == NULL. Remove the code
that is put under snp_target == NULL and snp_tty != NULL clause.

In snpclose(), do the snp_detach() before scheduling the snp device
destruction. Otherwise, after the return from snpclose(), the snp
device is already removed from the snp_list, but tty is still in
snooped state. Any attempt to do i/o on such tty cause panic because
ttytosnp() returns NULL.

de2fa7b8af Redefine bus_space_tag_t on PowerPC from a 32-bit integral to
a pointer to struct bus_space. The structure contains function
pointers that do the actual bus space access.

The reason for this change is that previously all bus space
accesses were little endian (i.e. had an explicit byte-swap
for multi-byte accesses), because all busses on Macs are little
endian.
The upcoming support for Book E, and in particular the E500
core, requires support for big-endian busses because all
embedded peripherals are in the native byte-order.

With this change, there's no distinction between I/O port
space and memory mapped I/O. PowerPC doesn't have I/O port
space. Busses assign tags based on the byte-order only.
For that purpose, two global structures exist (bs_be_tag and
bs_le_tag), of which the address can be taken to get a valid
tag.
