Move command descriptor setup to seperate function as preparation
for the following DMA setup fixes.
    
Note 1: also fix a harmless typo while moving it: sa_idx is initialized
	to dma->resi instead of dma->cmdi.
    
Note 2: errors from command descriptor setup are not propagated back,
	anymore, they can't be handled anyway and all conditions leading
	to errors should be checked earlier.

When the CryptoAPI instantiates a new algorithm, it performs a lookup
by driver name. Since hifn uses the same name for all modes of one
algorithm, the lookup may return an incorrect algorithm.
    
Change the name to use <mode>-<algo>-<devicename> to provide unique
names for the different combinations and devices.

The check for misalignment of the scatterlist data has two bugs:

- the source buffer doesn't need to be aligned at all
- the destination buffer and its size needs to be aligned to a multiple
  of 4, not to the crypto alg blocksize
    
Introduce symbolic constant for destination buffer alignment requirements,
use it instead of the crypto alg blocksize and remove the unnecessary
checks for source buffer alignment and change cra_alignmask to zero.

invalidate_inode_pages2_range() takes page offset arguments, not byte
ranges.

Another thought is that individual pages might perhaps get evicted by VM
pressure, in which case we might perhaps want to re-read not only the
evicted page, but all subsequent pages too (in case the server returns
more/less data per page so that the alignment of the next entry
changes). We should therefore remove the condition that we only do this on
page->index==0.

Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

The driver uses completely bogus rounding formula for calculating period from
the IDECLK frequency which gives one-off period values (e.g. 11 ns with 100 MHz
IDECLK) which in turn can lead to overclocked IDE transfer timings.  Actually,
rounding is just wrong in this case, so use a mere division for a safe result.

While at it, also:

- give 'ide_palm_clk' variable a more suitable name;

- get rid of the useless 'ideclkp' variable;

- drop the LISP stype 'p' postfix from the 'clkp' variable's name. :-)

Add __ide_default_irq() inline helper and use it instead of
ide_default_irq() in ide-probe.c and ns87415.c (all host drivers
except IDE PCI ones always setup hwif->irq so it is enough to
check only for I/O bases 0x1f0 and 0x170).

This fixes post-2.6.25 regression since ide_default_irq()
define could shadow ide_default_irq() inline.

  [S390] protect _PAGE_SPECIAL bit against mprotect

As Andy Whitcroft recently pointed out, the current powerpc version of
huge_ptep_set_wrprotect() has a bug.  It just calls ptep_set_wrprotect()
which in turn calls pte_update() then hpte_need_flush() with the 'huge'
argument set to 0.  This will cause hpte_need_flush() to flush the wrong
hash entries (of any).  Andy's fix for this is already in the powerpc
tree as commit 016b33c4.

I have confirmed this is a real bug, not masked by some other
synchronization, with a new testcase for libhugetlbfs.  A process write
a (MAP_PRIVATE) hugepage mapping, fork(), then alter the mapping and
have the child incorrectly see the second write.

Therefore, this should be fixed for 2.6.26, and for the stable tree.
Here is a suitable patch for 2.6.26, which I think will also be suitable
for the stable tree (neither of the headers in question has been changed
much recently).

It is cut down slighlty from Andy's original version, in that it does
not include a 32-bit version of huge_ptep_set_wrprotect().  Currently,
hugepages are not supported on any 32-bit powerpc platform.  When they
are, a suitable 32-bit version can be added - the only 32-bit hardware
which supports hugepages does not use the conventional hashtable MMU and
so will have different needs anyway.
