add comments and KASSERTs to make sure people don't forget to increase
XX_AUX_ENTRIES's when adding vectors.

introduce a variant with correct value.

It is wishful thinking that:
1. declaring a 32 bit syscall with 64 bit pointers
2. passing a struct with 32 bit pointers to a 64 bit function
is going to work.

(exec_free_emul_arg) to call the hook and then clear the ep_emul_arg

Change users/accessors to use these routines.

a shared lock. Make all calls outside of file systems respect it.
The calls from file systems need review.
No objections from tech-kern.

the base personality type in the low byte and
various flags in the upper bytes. for now just mask off
the flags to make sure the base type is one we accept.
store the current personality in the emuldata so that
we can return the expected value for PER_QUERY.

note that iopl(), ioperm() and modify_ldt() just call
the respective 64-bit handlers, which don't do anything yet.

d_type value in getdents() results, after the d_name field.
make our emulation do the same. fixes part of PR 43695.

static executables (such as newer versions of /sbin/ldconfig)
require this to work properly. since static executables
also don't have a PT_PHDR entry, use the same heuristic as
linux does to provide a value for AT_PHDR in this case.

- update the linux syscall table for each platform.
- support new-style (NPTL) linux pthreads on all platforms.
clone() with CLONE_THREAD uses 1 process with many LWPs
instead of separate processes.
- move the contents of sys__lwp_setprivate() into a new
lwp_setprivate() and use that everywhere.
- update linux_release[] and linux32_release[] to "2.6.18".
- adjust placement of emul fork/exec/exit hooks as needed
and adjust other emul code to match.
- convert all struct emul definitions to use named initializers.
- change the pid allocator to allow multiple pids to refer to the same proc.
- remove a few fields from struct proc that are no longer needed.
- disable the non-functional "vdso" code in linux32/amd64,
glibc works fine without it.
- fix a race in the futex code where we could miss a wakeup after
a requeue operation.
- redo futex locking to be a little more efficient.

VOP_UNLOCK(vp, flags) -> VOP_UNLOCK(vp): Remove the unneeded flags argument.
Welcome to 5.99.32.
Discussed on tech-kern.

per-page execution right was disabled (therefore leading to the inability
of the kernel to detect fraudulent use of memory mappings marked as not
being executable).
- replace cpu_feature and ci_feature_flags variables by cpu_feature and
ci_feat_val arrays. This makes it cleaner and brings kernel code closer
to the design of cpuctl(8). A warning will be raised for each CPU that
does not expose the same features as the Boot Processor (BP).
- the blacklist of CPU features is now a macro defined in the
specialreg.h header, instead of hardcoding it inside MD initialization
code; fix comments.
- replace checks against CPUID_TSC with the cpu_hascounter() function.
- clean up the code in init_x86_64(), as cpu_feature variables are set
inside cpu_probe().
- use cpu_init_msrs() for i386. It will be eventually used later for NX
feature under i386 PAE kernels.
- remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already
performed by cpu_hatch() through cpu_init_msrs().
- remove cpu_signature and feature_flags members from struct mpbios_proc
(they were never used).
This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under
a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines.
XXX Should kernel rev be bumped?
XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow.

clock_gettime syscall code (except for the copyout). Adjust all
corresponding syscalls to make use of it.

clock_getres1() function which can be used by emulations. Adjust all
clock_getres syscalls to now make of use it.

common clock_settime1() function.

in a row, and we need to try to read the next block, and have passed a
non-NULL cookie pointer to VOP_READDIR, ensure that we free the cookie
buffer before re-doing VOP_READDIR, so that we don't leak memory.
This fix is similar to nfs_serv.c revisions 1.115 + 1.124.
This should fix the long-standing problem observed by e.g. using Linux-
emulated programs to take backup of servers, which is one of the problems
which were reported in PR#42661.
Thanks to pooka@ for the hints for traversing the VOP* layer.
