2012-10-119P: Fix race between p9_write_work() and p9_fd_request()Simon Derr
Race scenario: thread A thread B p9_write_work() p9_fd_request() if (list_empty (&m->unsent_req_list)) ... spin_lock(&client->lock); req->status = REQ_STATUS_UNSENT; list_add_tail(..., &m->unsent_req_list); spin_unlock(&client->lock); .... if (n & POLLOUT && !test_and_set_bit(Wworksched, &m->wsched) schedule_work(&m->wq); --> not done because Wworksched is set clear_bit(Wworksched, &m->wsched); return; --> nobody will take care of sending the new request. This is not very likely to happen though, because p9_write_work() being called with an empty unsent_req_list is not frequent. But this also means that taking the lock earlier will not be costly.

Change the indicator from 0xffffffff in the "event_id" member to zero in the "cntr_mask" member. This removes the need to initialize entries that are unsupported. This also solves a problem where the number of entries in the table was increased based on a globel enum used for all platforms, but the new unsupported entries were not added for mips. This was leaving new table entries of all zeros that we not marked UNSUPPORTED.

2012-10-11MIPS: Align swapper_pg_dir to 64K for better TLB Refill code.David Daney
We can save an instruction in the TLB Refill path for kernel mappings by aligning swapper_pg_dir on a 64K boundary. The address of swapper_pg_dir can be generated with a single LUI instead of LUI/{D}ADDUI. The alignment of __init_end is bumped up to 64K so there are no holes between it and swapper_pg_dir, which is placed at the very beginning of .bss. The alignment of invalid_pmd_table and invalid_pte_table can be relaxed to PAGE_SIZE. We do this by using __page_aligned_bss, which has the added benefit of eliminating alignment holes in .bss.

2012-10-11Improve atomic.h robustnessJoshua Kinard
I've maintained this patch, originally from Thiemo Seufer in 2004, for a really long time, but I think it's time for it to get a look at for possible inclusion. I have had no problems with it across various SGI systems over the years. To quote the post here: http://www.linux-mips.org/archives/linux-mips/2004-12/msg00000.html "the atomic functions use so far memory references for the inline assembler to access the semaphore. This can lead to additional instructions in the ll/sc loop, because newer compilers don't expand the memory reference any more but leave it to the assembler. The appended patch uses registers instead, and makes the ll/sc arguments more explicit. In some cases it will lead also to better register scheduling because the register isn't bound to an output any more."

2012-10-11md: refine reporting of resync/reshape delays.NeilBrown
If 'resync_max' is set to 0 (as is often done when starting a reshape, so the mdadm can remain in control during a sensitive period), and if the reshape request is initially delayed because another array using the same array is resyncing or reshaping etc, when user-space cannot easily tell when the delay changes from being due to a conflicting reshape, to being due to resync_max = 0. So introduce a new state: (curr_resync == 3) to reflect this, make sure it is visible both via /proc/mdstat and via the "sync_completed" sysfs attribute, and ensure that the event transition from one delay state to the other is properly notified.

2012-10-11md/raid5: be careful not to resize_stripes too big.NeilBrown
When a RAID5 is reshaping, conf->raid_disks is increased before mddev->delta_disks becomes zero. This can result in check_reshape calling resize_stripes with a number that is too large. This particularly happens when md_check_recovery calls ->check_reshape(). If we use ->previous_raid_disks, we don't risk this. Signed-off-by: NeilBrown <neilb@suse.de>
