The strfilter__delete() function tests whether its argument is NULL and
then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

This change simply block-moves bodies of "save_registers"
and "restore_registers" routines into their callers.
Well, almost. In save_registers, we were saving %esp+4
to saved_context_esp, because we were in a subroutine,
there was one additional word (return address) on stack.
Now it is gone, and
Th "jmp" deleted by this patch in fact compiles to "jmp to next insn",
since ".p2align 4,,7" happens to not do any alignment -
aligning to 2^4 would require more than 7 bytes of padding:
00b0 :
b0: e8 fc ff ff ff call
b5: e8 8d ff ff ff call 47
ba: 6a 03
Get rid of the global variable saved_eip as it is only written to.
Jump directly to ret_point instead. No functionality change.
Run-tested.

The test checks that all registers are preserved across
32-bit syscalls. It tests syscalls through VDSO
(if available) and through INT 0x80, normally
and under ptrace.
If kernel is a 64-bit one, high registers (r8..r15) are poisoned
before call and checked afterwards. They must be either preserved

On 64-bit kernels, we don't need it any more: we handle context
tracking directly on entry from user mode and exit to user mode. On
32-bit kernels, we don't support context tracking at all, so these
hooks had no effect.
This doesn't change do_page_fault. Before we do that, we need to
make sure t

To prepare for the big rewrite of the error and interrupt exit
paths, we will need pt_regs completely filled in. It's already
completely filled in when error_exit runs, so rearrange interrupt
handling to match it. This will slow down interrupt handling very
slightly (eight instructions), but the

Once x86 exports its do_signal(), the prototypes will clash.
Fix the clash and also improve the code a bit: remove the unnecessary
kern_do_signal() indirection. This allows interrupt_end() to share
the 'regs' parameter calculation.
Also remove the unused return code to match x
If user code does SYSCALL32 or SYSENTER without a valid stack, then
our attempt to determine the syscall args will result in a failed
uaccess fault. Previously, we would try to recover by jumping to
the syscall exit code, but we'd run the syscall exit work even
though we never made it to the sysca
This will let us sprinkle sanity checks around the kernel without
making too much of a mess.

This test passes on 4.0 and fails on some newer kernels. Fortunately,
the failure is likely not a big deal. This test will make sure that
we don't break it further (e.g. OOPSing) as we clean up the entry
code and that we eventually fix the regression.
There's arguably no need to preserve the old
This is the first big batch of x86 asm-to-C conversion patches.
The exit-to-usermode code is copied in several places and is written
in a nasty combination of asm and C. It's not at all clear what
it's supposed to do, and the way it's structured makes it very hard
to work with. For example, it's

Is there a reason why it's important to build and load pmem as a
module? If I use CONFIG_BLK_DEV_PMEM=y (which is more convenient
given how I launch my KVM test appliance), should I expect any
