Change the names of the boolean functions autofs4_check_mount and
autofs4_check_tree to autofs4_mount_busy and autofs4_tree_busy respectively
and alters their return codes to suit in order to aid code readabilty.

Addresse a problem where stale dentrys stop mounts from happening.
When a mount point directory is pre-created and a non-existent entry within it
is requested a dentry ends up being created within the mount point directory
which stops future mounts. The problem is solved by ignoring negative,
unhashed dentrys in the mount point d_subdirs list.
Additionally the apparent cacheing of -ENOENT returns from requests is
removed. The test on d_time is a tautology and d_time is not initialised and
has an unexpected value. In short it doesn't do what it's meant to.
The cacheing of failed requests to the daemon is important and will be
followed up later.

This fixes a race in the starting of write_sigio_thread. Previously, some of
the data needed by the thread was initialized after the clone. If the thread
ran immediately, it would see the uninitialized data, including an empty
pollfds, which would cause it to hang.
We move the data initialization to before the clone, and adjust the error
paths and cleanup accordingly.

This fixes a process segfault where a signal was being delivered such that a
new stack page needed to be allocated to hold the signal frame. This was
tripping some logic in the page fault handler which wouldn't allocate the page
if the faulting address was more that 32 bytes lower than the current stack
pointer. Since a signal frame is greater than 32 bytes, this exercised that
case.
It's fixed by updating the SP in the pt_regs before starting to copy the
signal frame. Since those are the registers that will be copied on to the
stack, we have to be careful to put the original SP, not the new one which
points to the signal frame, on the stack.

For security reasons, UML in is_syscall() needs to have access to code in
vsyscall-page. The current implementation grants this access by explicitly
allowing access to vsyscall in access_ok_skas(). With this change,
copy_from_user() may be used to read the code. Ptrace access to vsyscall-page
for debugging already was implemented in get_user_pages() by mainline. In
i386, copy_from_user can't access vsyscall-page, but returns EFAULT.
To make UML behave as i386 does, I changed is_syscall to use
access_process_vm(current) to read the code from vsyscall-page. This doesn't
hurt security, but simplifies the code and prepares implementation of
stub-vmas.

Fix a gcc warning about losing qualifiers to the first argument of
copy_from_user. The typeof change for correctness, and fixes a lot of the
warnings, but there are some cases where x has some extra qualifiers, like
volatile, which copy_from_user can't know about. For these, the void * cast
seems to be necessary.
Also cleaned up some of the whitespace and got rid of the emacs comment at the

Current timer_pm.c reads I/O port triple times, in order to avoid the bug
of chipset. But I/O port is slow.
2.6.16 (pmtmr)
Simple gettimeofday: 3.6532 microseconds
2.6.16+patch (pmtmr)
Simple gettimeofday: 1.4582 microseconds
[if chip is buggy, probably it will be 7us or more in 4.2% of probability.]
This patch adds blacklist of buggy chip, and if chip is not buggy, this
uses fast normal version instead of slow workaround version.
If chip is buggy, warnings "pmtmr is slow". But sounds like there is gray
zone. I found the PIIX4 errata, but I couldn't find the ICH4 errata. But
some motherboard seems to have problem.
So, if we found a ICH4, generate warnings, and use a workaround version.
If user's ICH4 is good, the user can specify the "pmtmr_good" boot
parameter to use fast version.

<linux@horizon.com> wrote:
This is an extremely well-known technique. You can see a similar version that
uses a multiply for the last few steps at
http://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel whch
refers to "Software Optimization Guide for AMD Athlon 64 and Opteron
Processors"
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/25112.PDF
It's section 8.6, "Efficient Implementation of Population-Count Function in
32-bit Mode", pages 179-180.
It uses the name that I am more familiar with, "popcount" (population count),
although "Hamming weight" also makes sense.
Anyway, the proof of correctness proceeds as follows:
b = a - ((a >> 1) & 0x55555555);
c = (b & 0x33333333) + ((b >> 2) & 0x33333333);
d = (c + (c >> 4)) & 0x0f0f0f0f;
#if SLOW_MULTIPLY
e = d + (d >> 8)
f = e + (e >> 16);
return f & 63;
#else
/* Useful if multiply takes at most 4 cycles */
return (d * 0x01010101) >> 24;
#endif
The input value a can be thought of as 32 1-bit fields each holding their own
hamming weight. Now look at it as 16 2-bit fields. Each 2-bit field a1..a0
has the value 2*a1 + a0. This can be converted into the hamming weight of the
2-bit field a1+a0 by subtracting a1.
That's what the (a >> 1) & mask subtraction does. Since there can be no
borrows, you can just do it all at once.
Enumerating the 4 possible cases:
0b00 = 0 -> 0 - 0 = 0
0b01 = 1 -> 1 - 0 = 1
0b10 = 2 -> 2 - 1 = 1
0b11 = 3 -> 3 - 1 = 2
The next step consists of breaking up b (made of 16 2-bir fields) into
even and odd halves and adding them into 4-bit fields. Since the largest
possible sum is 2+2 = 4, which will not fit into a 4-bit field, the 2-bit
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
"which will not fit into a 2-bit field"
fields have to be masked before they are added.
After this point, the masking can be delayed. Each 4-bit field holds a
population count from 0..4, taking at most 3 bits. These numbers can be added
without overflowing a 4-bit field, so we can compute c + (c >> 4), and only
then mask off the unwanted bits.
This produces d, a number of 4 8-bit fields, each in the range 0..8. From
this point, we can shift and add d multiple times without overflowing an 8-bit
field, and only do a final mask at the end.
The number to mask with has to be at least 63 (so that 32 on't be truncated),
but can also be 128 or 255. The x86 has a special encoding for signed
immediate byte values -128..127, so the value of 255 is slower. On other
processors, a special "sign extend byte" instruction might be faster.
On a processor with fast integer multiplies (Athlon but not P4), you can
reduce the final few serially dependent instructions to a single integer
multiply. Consider d to be 3 8-bit values d3, d2, d1 and d0, each in the
range 0..8. The multiply forms the partial products:
d3 d2 d1 d0
d3 d2 d1 d0
d3 d2 d1 d0
+ d3 d2 d1 d0
----------------------
e3 e2 e1 e0
Where e3 = d3 + d2 + d1 + d0. e2, e1 and e0 obviously cannot generate
any carries.
