Host software could issue interrupts to ME firmware, using H_IG bit. While
Setting H_IG bit, host software should preserve all the other bits in H_CSR
unchanged. In the original function which sets H_CSR register, they first read
the register, then set some bits, and write the whole 32bits back to the
register. And that the special behavior of H_IS (write-one-to-zero) causes problem.
This patch fixes the issue in the following ways:
- Modify heci_set_csr_register() function so that it doesn't change H_IS bit.
- Add interface heci_csr_clear_his() to clear H_IS bit. This function is called
after H_IS checking (dev->host_hw_state & H_IS == H_IS).
- In original heci_csr_disable_interrupts() function, it not only clears H_IE
bit, sometimes it also clears H_IS bit. This patch separates the two parts.
- Avoid calling write_heci_register() function to set H_CSR register directly,
and instead using heci_set_csr_register() function

- Fix typo for enum HECI_WRITE.
- Fix timeout issue. If the time period is greater or equal 15s, it's timeout.
- Add 10ms wait time after disconnect, to ensure that hardware is ready.
Otherwise in the next time connection, hardware resource may be busy.

Before all testcases, do:
mknod /dev/caphash c 253 0
mknod /dev/capuse c 253 1
This patch does the following:
1. caphash write of > CAP_NODE_SIZE bytes overruns node_ptr->data
(test: cat /etc/mime.types > /dev/caphash)
2. make sure we don't dereference a NULL cap_devices[0].head
(test: cat serge@root@abab > /dev/capuse)
3. don't let strlen dereference a NULL target_user etc
(test: echo ab > /dev/capuse)
4. Don't leak a bunch of memory in cap_write(). Note that
technically node_ptr is not needed for the capuse write case.
As a result I have a much more extensive patch splitting up
cap_write(), but I thought a smaller patch that is easier to test
and verify would be a better start. To test:
cnt=0
while [ 1 ]; do
echo /etc/mime.types > /dev/capuse
if [ $((cnt%25)) -eq 0 ]; then
head -2 /proc/meminfo
fi
cnt=$((cnt+1))
sleep 0.3
done
Without this patch, it MemFree steadily drops. With the patch,
it does not.
I have *not* tested this driver (with or without these patches)
with factotum or anything - only using the tests described above.

Clean up the code in lowmem_shrink() for the Android low memory killer so
that it follows the kernel coding style.
It's unnecessary to check for p->oomkilladj >= min_adj if the selected
task's oomkilladj score is stored since get_mm_rss() will always be
greater than zero.
