Check the return value of led_classdev_register and unregister all registered devices, if registering one device fails. Also the dynamic memory handling is totally bogus. You can't allocate multiple chunks via kzalloc() and expect them to be in order later. I wonder how this ever worked. Signed-off-by:

On initialization, we first do the ioremap and then register the led devices. On deinitialization, we do it in reverse order. This prevents someone calling into the brightness_set functions with an invalid latch_address. Signed-off-by:

Fix infinite recursive notifier in the fbdev layer. This causes recursive locking. Dmitry Baryshkov found the problem and confirmed that the patch fixes the bug.

This fixes a regression that came with 934b2857 ("[S390] nohz/sclp: disable timer on synchronous waits."). If udelay() gets called from a disabled context it sets the clock comparator to a value where it expects the next interrupt. When the interrupt happens the clock comparator gets not reset and therefore the interrupt condition doesn't get cleared. The result is an endless timer interrupt loop. In addition this patch fixes also the following: rcutorture reveals that our __udelay implementation is still buggy, since it might schedule tasklets, but prevents their execution: NOHZ: local_softirq_pending 42 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 142 NOHZ: local_softirq_pending 02 To fix this we make sure that only the clock comparator interrupt is enabled when the enabled wait psw is loaded. Also no code gets called anymore which might schedule tasklets. Signed-off-by:

Rework of SMTC support to make it work with the new clock event system, allowing "tickless" operation, and to make it compatible with the use of the "wait_irqoff" idle loop. The new clocking scheme means that the previously optional IPI instant replay mechanism is now required, and has been made more robust. Signed-off-by:

Doing 'WARN_ON(preempt_count())' was horribly horribly wrong, and would cause tons of warnings at bootup if PREEMPT was enabled because the initcalls currently run with the kernel lock, which increments the preempt count. At the same time, the warning was also insufficient, since it didn't check that interrupts were enabled. The proper debug function to use for something that can sleep and wants a warning if it's called in the wrong context is 'might_sleep()'. Reported-by:

This is loosely based on a patch by Jesse Barnes to check the user-space PCI mappings though the sysfs interfaces. Quoting Jesse's original explanation: It's fairly common for applications to map PCI resources through sysfs. However, with the current implementation, it's possible for an application to map far more than the range corresponding to the resourceN file it opened. This patch plugs that hole by checking the range at mmap time, similar to what is done on platforms like sparc64 in their lower level PCI remapping routines. It was initially put together to help debug the e1000e NVRAM corruption problem, since we initially thought an X driver might be walking past the end of one of its mappings and clobbering the NVRAM. It now looks like that's not the case, but doing the check is still important for obvious reasons. and this version of the patch differs in that it uses a helper function to clarify the code, and does all the checks in pages (instead of bytes) in order to avoid overflows when doing "<< PAGE_SHIFT" etc. Acked-by:

e1000e was apparently calling two functions that attempted to reserve the SWFLAG bit for exclusive (to hardware and firmware) access to the PHY and NVM (aka eeprom). These accesses could possibly call msleep to wait for the resource which is not allowed from interrupt context. Signed-off-by:

in the process of debugging things, noticed that the swflag is not reset by the driver after reset, and the swflag is probably not reset unless management firmware clears it after 100ms. Signed-off-by:

When we initialise a compound page we initialise the page flags and head page pointer for all base pages spanned by that page. When we initialise a gigantic page (a page of order greater than or equal to MAX_ORDER) we have to initialise more than MAX_ORDER_NR_PAGES pages. Currently we assume that all elements of the mem_map in this page are contigious in memory. However this is only guarenteed out to MAX_ORDER_NR_PAGES pages, and with SPARSEMEM enabled they will not be contigious. This leads us to walk off the end of the first section and scribble on everything which follows, BAD. When we reach a MAX_ORDER_NR_PAGES boundary we much locate the next section of the mem_map. As gigantic pages can only be maximally aligned we know this will occur at exact multiple of MAX_ORDER_NR_PAGES pages from the start of the page. This is a bug fix for the gigantic page support in hugetlbfs. Credit to Mel Gorman for spotting the issue. Signed-off-by:

The previous patch db203d53 ("mm: tiny-shmem fix lock ordering: mmap_sem vs i_mutex") to fix the lock ordering in tiny-shmem breaks shared anonymous and IPC memory on NOMMU architectures because it was using the expanding truncate to signal ramfs to allocate a physically contiguous RAM backing the inode (otherwise it is unusable for "memory mapping" it to userspace). However do_truncate is what caused the lock ordering error, due to it taking i_mutex. In this case, we can actually just call ramfs directly to allocate memory for the mapping, rather than go via truncate. Acked-by:

__test_page_isolated_in_pageblock() in mm/page_isolation.c has a comment saying that the caller must hold zone->lock. But the only caller of that function, test_pages_isolated(), does not hold zone->lock and the lock is also not acquired anywhere before. This patch adds the missing zone->lock to test_pages_isolated(). We reproducibly run into BUG_ON(!PageBuddy(page)) in __offline_isolated_pages() during memory hotplug stress test, see trace below. This patch fixes that problem, it would be good if we could have it in 2.6.27. kernel BUG at /home/autobuild/BUILD/linux-2.6.26-20080909/mm/page_alloc.c:4561! illegal operation: 0001 [#1] PREEMPT SMP Modules linked in: dm_multipath sunrpc bonding qeth_l3 dm_mod qeth ccwgroup vmur CPU: 1 Not tainted 2.6.26-29.x.20080909-s390default #1 Process memory_loop_all (pid: 10025, task: 2f444028, ksp: 2b10dd28) Krnl PSW : 040c0000 801727ea (__offline_isolated_pages+0x18e/0x1c4) R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:0 CC:0 PM:0 Krnl GPRS: 00000000 7e27fc00 00000000 7e27fc00 00000000 00000400 00014000 7e27fc01 00606f00 7e27fc00 00013fe0 2b10dd28 00000005 80172662 801727b2 2b10dd28 Krnl Code: 801727de: 5810900c l %r1,12(%r9) 801727e2: a7f4ffb3 brc 15,80172748 801727e6: a7f40001 brc 15,801727e8 >801727ea: a7f4ffbc brc 15,80172762 801727ee: a7f40001 brc 15,801727f0 801727f2: a7f4ffaf brc 15,80172750 801727f6: 0707 bcr 0,%r7 801727f8: 0017 unknown Call Trace: ([<0000000000172772>] __offline_isolated_pages+0x116/0x1c4) [<00000000001953a2>] offline_isolated_pages_cb+0x22/0x34 [<000000000013164c>] walk_memory_resource+0xcc/0x11c [<000000000019520e>] offline_pages+0x36a/0x498 [<00000000001004d6>] remove_memory+0x36/0x44 [<000000000028fb06>] memory_block_change_state+0x112/0x150 [<000000000028ffb8>] store_mem_state+0x90/0xe4 [<0000000000289c00>] sysdev_store+0x34/0x40 [<00000000001ee048>] sysfs_write_file+0xd0/0x178 [<000000000019b1a8>] vfs_write+0x74/0x118 [<000000000019b9ae>] sys_write+0x46/0x7c [<000000000011160e>] sysc_do_restart+0x12/0x16 [<0000000077f3e8ca>] 0x77f3e8ca Signed-off-by:

Commit 22af89aa ("fbcon: replace mono_col macro with static inline") changed the order of operations for computing monochrome color values. This generates 0xffff000f instead of 0x0000000f for a 4 bit monochrome color, leading to image corruption if it is passed to cfb_imageblit or other similar functions. Fix it up.
