f52ecc3346 Restored clearing of the bss, except for putting it in a correct place
with up to date comments.  This fixes booting kernels with boot2
(except for loss of the features provided by loader) and is suitable
for MFC.  Contrary to the old comments, most loaders don't clear the bss.
biosboot lost clearing of the bss in a code crunch in 1997, and boot2
never did it.

kan didn't notice the problem with gcc-3.3 putting variables that are
initialized to 0 in the bss until after committing gcc-3.3 because he
was already using essentially this patch.  Before gcc-3.3, only the
non-critical `bootdev' variable was clobbered by clearing the bss.

fa6a7ef6e4 Process events from the ATM drivers. Carrier change and PVC change
messages are forwarded as netgraph control messages to the node
that is connected to the manage hook. If that hook is not connected,
the event is lost. Flow control events are converted to netgraph
flow control messages and send along the hook that is connected to
the flow controlled VC. ACR change events are converted to control
messages and sent along the hook for the given VC.

011a891406 Don't hide the name of tmpstk, since there is no need to do so and the
HIDENAME() macro seems to be unimplementable in C.  (HIDENAME() used
to use invalid token pasting using ## for the STDC case until gcc
started rejecting that; now it uses unportable token pasting using
juxtaposition in all cases.)  This reduces use of HIDENAME() in the
kernel to only i386 and amd64 profiling code so that it doesn't bite
most kernels whenever gcc becomes stricter.  Problems with HIDENAME()
in userland are smaller because userland mostly doesn't use strict
flags yet.  There are some advantages to hiding the name of mcount,
but newer arches shouldn't do it; only amd64 does.

MFC after:	3 days

On second thoughts hide tmpstk better by staticizing it.

7576b4b4c0 Try to make 'uname -a' look more like it does on Linux:
- cut the version string at the newline, suppressing information about
   who built the kernel and in what directory.  Most of this information
   was already lost to truncation.

 - on i386, return the precise CPU class (if known) rather than just
   "i386".  Linux software which uses this information to select
   which binary to run often does not know what to make of "i386".

aae962d56e Fix a problem that occurs when truncating files on NFSv3 mounts: we need
to set np->n_size back to the desired size again after calling
nfs_meta_setsize(), since it could end up in nfs_loadattrcache() getting
called, which would change n_size back to the value it had before the
truncate request was issued. The result of this bug is that the size info
cached in the nfsnode becomes incorrect, lseek(fd, ofs, SEEK_END) seeks
past the end of the file, stat() returns the wrong size, etc.

9080ff25cf Rename VOP_RMEXTATTR() to VOP_DELETEEXTATTR() for consistency with the
kernel ACL interfaces and system call names.

Break out UFS2 and FFS extattr delete and list vnode operations from
setextattr and getextattr to deleteextattr and listextattr, which
cleans up the implementations, and makes the results more readable,
and makes the APIs more clear.

2e4a71cdb1 When exporting file descriptor data for threads invoking the
kern.file sysctl, don't return information about processes that
fail p_cansee(td, p).  This prevents sockstat and related
programs from seeing file descriptors owned by processes not
in the same jail as the thread, as well as having implications
for MAC, etc.

This is a partial solution: it permits an information leak about
the number of descriptors in the sizing calculation (but this is
not new information, you can also get it from kern.openfiles),
and doesn't attempt to mask file descriptors based on the
properties of the descriptor, only the process referencing it.
However, it provides most of what you want under most
circumstances, without complicating the locking.

1deac58179 Add a PATH_INQ flag, PIM_NO_6_BYTE, which indicates the SIM never wishes to
receive 6 byte commands.  Add a check for this flag to da(4) and cd(4) so
that they honor it.  This is a quick workaround for many devices (especially
USB) that require da(4) quirks to operate.  The more complete approach is
to finish the new transport code which will be aware of the SCSI version a
transport implements.

266c520a5a Changed the data types of three index variables, two of them
in the `video_state' structure, to larger ones (from u_char to
u_short).  Each can now hold values at least as large as the
size of the array it is meant to point into.

This eliminates warnings printed by GCC 3.3.1 and hence makes
pcvt compilable using -Werror.

c39be346e3 Changed the type of the variable `qidx' from u_int8_t to int,
mainly to quiet a warning emitted by GCC 3.3 about comparing
a variable to a value which is larger than the former can hold.

The value was checked to make sure the `np->squeue' array is
not accessed behind its boundary.
This worked due to possibly accidental truncation when
(np->squeueput + 1) was larger than or equal to MAX_START (256)
when it was assigned to `qidx'.

`qidx' is used to hold the next position in the start queue
for an insertion.  The new type was chosen because some other
code in the function ncr_freeze_devq() also uses plain integers
to hold those indices.

Wrapped the line after the closing parenthesis of an `if'
condition.
