Fix a potential bug that TX/RX might stall when TX rate limit reached.
This change is almost the same as the RX rate limit bug fix in ixgbe.c
rev. 1.121. I've never got any stall, but this must be a bug.

(msaitoh)

Improve the SVS initialization.

Declare x86_patch_window_open() and x86_patch_window_close(), and globalify
x86_hotpatch().

Introduce svs_enable() in x86/svs.c, that does the SVS hotpatching.

Change svs_init() to take a bool. This function gets called twice; early
when the system just booted (and nothing is initialized), lately when at
least pmap_kernel has been initialized.

(maxv)

Add a dynamic detection for SVS.

The SVS_* macros are now compiled as skip-noopt. When the system boots, if
the cpu is from Intel, they are hotpatched to their real content.
Typically:

jmp 1f
int3
int3
int3
... int3 ...
1:

gets hotpatched to:

movq SVS_UTLS+UTLS_KPDIRPA,%rax
movq %rax,%cr3
movq CPUVAR(KRSP0),%rsp

These two chunks of code being of the exact same size. We put int3 (0xCC)
to make sure we never execute there.

In the non-SVS (ie non-Intel) case, all it costs is one jump. Given that
the SVS_* macros are small, this jump will likely leave us in the same
icache line, so it's pretty fast.

The syscall entry point is special, because there we use a scratch uint64_t
not in curcpu but in the UTLS page, and it's difficult to hotpatch this
properly. So instead of hotpatching we declare the entry point as an ASM
macro, and define two functions: syscall and syscall_svs, the latter being
the one used in the SVS case.

While here 'syscall' is optimized not to contain an SVS_ENTER - this way
we don't even need to do a jump on the non-SVS case.

When adding pages in the user page tables, make sure we don't have PG_G,
now that it's dynamic.

A read-only sysctl is added, machdep.svs_enabled, that tells whether the
kernel uses SVS or not.

More changes to come, svs_init() is not very clean.

Increment rxr->packets correctly in ixgbe_rxeof() to calculate ITR value

XXX pullup-8

(msaitoh)

- Fix a bug that RX may stall on heavy load on ixg(4) derived from FreeBSD's
AIM (Auto Interrupt Moderation) bug.
When I use a machine as a NFS client, sometimes one of queue pairs doesn't
get any interrupt other than every second tick via ixgbe_local_timer1().
When the problem occured, the queue pair's hw.ixgM.qN.interrupt_rate is
always 500000. When this problem occuring, set hw.ixgM.qN.interrupt_rate lower
than 166667 recover from stall. i.e.:

  sysctl -w hw.ixgM.qN.interrupt_rate=166667 (don't revocer)
  sysctl -w hw.ixgM.qN.interrupt_rate=166666 (recover)

  Relatios between the interrupt_rate and EICR's ITR_INTERVAL field is as
follows:

int_rate | EICR[11:0]  | interval in us | recover |
          |(ITR_INTERVAL)| (10G and 1G)  |        |
---------+--------------+----------------+---------+
  500000 | 0x008(0)    |              2 |    not |
  166667 | 0x010(1)    |              4 |    not |
  166666 | 0x018(2)    |              6 | recover |

  The reason why int_rate becomes 500000 is that xgbe_tx_eof() doesn't
increment rxr->packets(*1). Even if we fix rxr->packets' bug, interrupt_rate
might become greater than 166666 and it might cause stall.

  While reading datasheets, knakahara noticed a section titled with "ITR
Affect on RSC Functionality". It says "When RSC is enabled on specific RX
queues, the associated ITR interval with these queus must be enabled and must
be larger (in time uints) than RSC delay". Currently, RSC_DELAY field in the
GPIE register is 0 and it means 4us for 10G and 1G. The greater ITR_INTERVAL
value of 4us is 6us == 166666. Yes, BINGO!

  This description is noted in 82599 and newer datasheets and not in 82598
datasheet. I don't know if 82598 has this limitation but, I apply this
limitation all of chips.

(*1) Note that this bug is going to be fixed in the next commit to distinct
between two different bugs.

- The bitfield of EITR register is different between 82598 and others.
Only ixgbe_msix_que() taken care of it. Make new function ixgbe_eitr_write()
and use it in all of functions which modify ITR_INTERVAL.

Fix a huge privilege separation vulnerability in Xen-amd64.
On amd64 the kernel runs in ring3, like userland, and therefore SEL_KPL
equals SEL_UPL. While Xen can make a distinction between usermode and
kernelmode in %cs, it can't when it comes to iopl. Since we set SEL_KPL
in iopl, Xen sees SEL_UPL, and allows (unprivileged) userland processes
to read and write to the CPU ports.
It is easy, then, to completely escalate privileges; by reprogramming the
PIC, by reading the ATA disks, by intercepting the keyboard interrupts
(keylogger), etc.
Declare IOPL_KPL, set to 1 on Xen-amd64, which allows the kernel to use
the ports but not userland. I didn't test this change on i386, but it

Support arbitrary softint IPLs in high priority xcall
The high priority xcall supported only a softint of IPL_SOFTSERIAL. It meant
that it didn't work for xcall callbacks depending on lower IPLs than
IPL_SOFTSERIAL.
The change makes xcall have multiple softints of IPLs and allow users to specify
arbitrary IPLs. Users can specify an IPL by XC_HIGHPRI_IPL passed to the 1st
argument of xc_broadcast or xc_unicast.
Note that xcall still serves requests one by one (i.e., doesn't run them

sys/dev/pci/virtio_pci.c: 1.2 via patch to sys/dev/pci/virtio.c
Explicitly enable PCI_COMMAND_MASTER_ENABLE and PCI_COMMAND_IO_ENABLE.
Recent versions of VirtualBox do not enable bus-mastering by default -
this will be fixed, but it doesn't hurt to do it ourselves too.

(snj)

Code is fixed, so hiding the warning is not necessary any more.

fix _UC_MACHINE32_FP() -- use 32 bit pointer value so that [15] is
the right offset.  do this by using __greg32_t, which is only in
the sparc64 version, and these are only useful there, so move them.

Var_Set: avoid SIGSEGV if val is NULL

A NULL val is handled gracefully (by VarAdd) when
var is not previously set, so we ought not crash

Declare check_swapgs in an ASM macro. No real functional change.

(maxv)

Use ASM macros for the rest of the entry points. No real functional
change. Now the format of the entry points is:

.macro TRAP_ENTRY_POINT_xx arg1,arg2,arg3
...the asm code...
.endm

TEXT_USER_BEGIN
TRAP_ENTRY_POINT_xx arg1,arg2,arg3
TEXT_USER_END

(maxv)

Declare and use TRAP_ENTRY_POINT_DNA. This time we don't give an is_ztrap
argument, because the macro is tied to the entry point, and it would be
wrong to suggest the paramater is controllable. No real functional change.

Add NETATALKDEBUG to the option header and include that in the main source

Rename i8259_stubs -> legacy_stubs. We will want the entries to have the

Add svs_init. This is where we will detect the CPU and decide whether

Add a test demonstrating thst LOCAL_PEEREID is busted.

Improve _UC_MACHINE_FP() for SPARC/SPARC64

Introduce a static inline function _uc_machine_fp() that contains improved

Algorithm:

#  if defined (__arch64__)
  stk_ptr = (uptr *) (*sp + 2047);
#  else
  stk_ptr = (uptr *) *sp;
#  endif
  *bp = stk_ptr[15];

Drop explicit loop prefix. GAS doesn't care and LLVM doesn't support it.
Drop the need for assembling with GAS. While LLVM is using a suboptimal
encoding of for hard-coded memory writes, it shouldn't affect
functionality. It just wastes three bytes with extra prefixes.
