[PATCH] s390: fba dasd i/o errors

The FBA discipline does not use retries for failed requests.  A request fails
after the first unsuccessful start attempt.  There are some rare conditions
(e.g.  CIO path recovery) in which the start of an i/o on a fba device can
fail.  A tiny amount of retries is therefore reasonable.

[PATCH] s390: external call performance

The kernel uses the SIGP external call order code to signal other CPUs.  When
running with dedicated CPUs external calls don't get delivered immediately but
within a fixed polling invervall.  This can lead to delays where the system
appears to do nothing.  Replace the SIGP external call order with the SIGP
emergency call order since this one gets delivered immediately.

[PATCH] s390: find_next_{zero}_bit fixes

The find_next_{zero}_bit primitives on s390* should never return a bit number
bigger then the bit field size.  In the case of a bitfield that doesn't end on
a word boundary, an offset that makes the search start at the last word of the
bit field and the last word doesn't contain any zero/one bits the search is
continued with a call to find_first_bit with a negative size.  The search
normally ends pretty quickly because the words following the bit field contain
a mix of zeros and ones.  But the bit number that is returned in this case is
too big.

To fix this and additional if to check for this case is needed.  To make the
code easier to read I removed the assembler parts from the
find_next_{zero}_bit functions, the C-ified code is as good.

[PATCH] s390: spin lock retry

Split spin lock and r/w lock implementation into a single try which is done
inline and an out of line function that repeatedly tries to get the lock
before doing the cpu_relax().  Add a system control to set the number of
retries before a cpu is yielded.

The reason for the spin lock retry is that the diagnose 0x44 that is used to
give up the virtual cpu is quite expensive.  For spin locks that are held only
for a short period of time the costs of the diagnoses outweights the savings
for spin locks that are held for a longer timer.  The default retry count is
1000.

[PATCH] ppc64: remove another fixed address constraint

Presently the LparMap, one of the structures the kernel shares with the
legacy iSeries hypervisor has a fixed offset address in head.S.  This patch
changes this so the LparMap is a normally initialized structure, without
fixed address.  This allows us to use macros to compute some of the values
in the structure, which wasn't previously possible because the assembler
always uses signed-% which gets the wrong answers for the computations in
question.

Unfortunately, a gcc bug means that doing this requires another structure
(hvReleaseData) to be initialized in asm instead of C, but on the whole the
result is cleaner than before.

[PATCH] ppc64: dynamically allocate segment tables

PPC64 machines before Power4 need a segment table page allocated for each
CPU.  Currently these are allocated statically in a big array in head.S for
all CPUs.  The segment tables need to be in the first segment (so
do_stab_bolted doesn't take a recursive fault on the stab itself), but
other than that there are no constraints which require the stabs for the
secondary CPUs to be statically allocated.

This patch allocates segment tables dynamically during boot, using
lmb_alloc() to ensure they are within the first 256M segment.  This reduces
the kernel image size by 192k...

Tested on RS64 iSeries, POWER3 pSeries, and POWER5.

[PATCH] Remove bogus warning in page_alloc.c

Originally __free_pages_bulk used the relative page number within a zone to
define its buddies.  This meant that to maintain the "maximally aligned"
requirements (that an allocation of size N will be aligned at least to N
physically) zones had to also be aligned to 1<<MAX_ORDER pages.  When
__free_pages_bulk was updated to use the relative page frame numbers of the
free'd pages to pair buddies this released the alignment constraint on the
'left' edge of the zone.  This allows _either_ edge of the zone to contain
partial MAX_ORDER sized buddies.  These simply never will have matching
buddies and thus will never make it to the 'top' of the pyramid.

The patch below removes a now redundant check ensuring that the mem_map was
aligned to MAX_ORDER.

[PATCH] check_user_page_readable() deadlock fix

Fix bug identifued by Richard Purdie <rpurdie@rpsys.net>.

oprofile calls check_user_page_readable() from interrupt context, so we
deadlock over various VFS locks.

But check_user_page_readable() doesn't imply either a read or a write of the
page's contents.  Change __follow_page() so that check_user_page_readable()
can tell __follow_page() that we're not accessing the page's contents, and use
that info to avoid the troublesome lock-takings.

Also, make follow_page() inline for the single callsite in memory.c to save a
bit of stack space.

This is safe because interaction with xattrs is complete, and the relock is
just to balance out the release in the caller.

[PATCH] Change PowerPC MPC8xx maintainer

As Marcelo has been spending a great deal of time working on MPC8xx
systems of late (thanks!) and has more time than I do now for it, I'm
handing this over to him.

[PATCH] fix MAX_USER_RT_PRIO and MAX_RT_PRIO

Here's the patch again to fix the code to handle if the values between
MAX_USER_RT_PRIO and MAX_RT_PRIO are different.

Without this patch, an SMP system will crash if the values are
different.
