instead of removing the file and issue a warning about
the removal, do not do any operation at all in case -P
is specified when the dinode has hard links.
With -f and -P specified together, we assume that the
user wants rm to overwrite the contents of the file
and remove it (destroy the contents of file but leave
its hard links as is).
The reason of doing it this way is that, in case where
a hard link is created by a malicious user (currently
this is permitted even if the user has no access to the
file). Losing the link can potentially mean that the
actual owner would lose control completely to the user
who wants to obtain access in a future day.

with an expression as the argument like __bswap32_const(42 << 23 | 13)

as appropriate so the bytes which exceed the width of the respective
__bswapN_const() macro in invocations like __bswap16_const(0xdead600d)
are ignored like it's the case with the corresponding __bswapN_var()

only those bars that had addresses assigned by the BIOS and where the
bridges were properly programmed. Now even unprogrammed ones work.
This was needed for sun4v. We still only implement up to 2GB memory
ranges, even for 64-bit bars. PCI standards at least through 2.2 say
that this is the max (or 1GB is, I only know it is < 32bits).
o Always define pci_addr_t as uint64_t. A pci address is always 64-bits,
but some hosts can't address all of them.
o Preserve the upper half of the 64-bit word during resource probing.
o Test to make sure that 64-bit values can fit in a u_long (true on some
platforms, but not others). Don't use those that can't.
o minor pedantry about data sizes.
o Better bridge resource reporting in bootverbose case.
o Minor formatting changes to cope with different data types on different
platforms.

are no longer limited to a virtual address space of 16 megabytes,
only mask high two bits of a virtual address. This allows to load
larger kernels (up to 1 gigabyte). Not masking addresses at all
was a bad idea on machines with less than >3G of memory -- kernels
are linked at 0xc0xxxxxx, and that would attempt to load a kernel
at above 3G. By masking only two highest bits we stay within the
safe limits while still allowing to boot larger kernels.

dynamic nature (if no native aio code is available, the linux part
returns ENOSYS because of missing requisites) should be solved differently
than it is.
All this will be done in P4.
Not included in this commit is a backout of the changes to the native aio
code (removing static in some places). Those changes (and some more) will
also be needed when the reworked linux aio stuff will reenter the tree.

not completely decided at config time. Just don't default to using
the TSC if there are multiple active CPUs. Also, don't default to
using the TSC if it is broken. SMP ifdefs are still used to disallow
using perfmon since perfmon is always broken if SMP is just configured.
This only helps much for SMP kernels running on 1 CPU. The overheads
for using the i8254 cputime clock were a bit too high on 486/33's, and
now on multi-GHz CPUs they are usually in the 99-99.9% range. Switching
from the old default of an i8254 clock to the TSC works poorly because
the overheads are not recalibrated.
Use the same condition for declaring perfmon stuff as for using it.
Call vfs_setdirty_locked_object() from vfs_busy_pages() instead of
vfs_setdirty(), thereby eliminating a second acquisition and release
of the same vm object lock.

- Don't use a frame pointer. Our callers need a frame pointer, but we
could only use one to support things that aren't supported. (These
things are:
- profiling of profiling
- debugging of profiling. The core ENTRY() macro doesn't support
forcing a frame pointer for debugging, so don't do more here.)
