* oprofile/x86: remove node check in AMD IBS initializationRobert Richter2010-03-15
| | | | | | | | | | | | | | | commit 89baaaa98a10cad5cc8516c7208b02d9fc711890 upstream. Standard AMD systems have the same number of nodes as there are northbridge devices. However, there may kernel configurations (especially for 32 bit) or system setups exist, where the node number is different or it can not be detected properly. Thus the check is not reliable and may fail though IBS setup was fine. For this reason it is better to remove the check.

* oprofile: remove tracing build dependencyRobert Richter2010-03-15
| | | | | | | | | | | | | | | | | | | | commit 18b4a4d59e97e7ff13ee84b5bec79f3fc70a9f0a upstream. The commit 1155de4 ring-buffer: Make it generally available already made ring-buffer available without the TRACING option enabled. This patch removes the TRACING dependency from oprofile. Fixes also oprofile configuration on ia64. The patch also applies to the 2.6.32-stable kernel.

* macintosh/hwmon/ams: Fix device removal sequenceJean Delvare2010-03-15
| | | | | | | | | | | | | | | | | | | | | commit 98ceb75c7c14eada76b0aa9f03a635a735cee3cb upstream. Some code that is in ams_exit() (the module exit code) should instead be called when the device (not module) is removed. It probably doesn't make much of a difference in the PMU case, but in the I2C case it does matter. I make no guarantee that my fix isn't racy, I'm not familiar enough with the ams driver code to tell for sure.

* macintosh/therm_adt746x: Fix sysfs attributes lifetimeJean Delvare2010-03-15
| | | | | | | | | | | | | | | | | | | | | | | commit 33a470f6d5e1879c26f16f6b34dc09f82d44f6e9 upstream. Looking at drivers/macintosh/therm_adt746x.c, the sysfs files are created in thermostat_init() and removed in thermostat_exit(), which are the driver's init and exit functions. These files are backed-up by a per-device structure, so it looks like the wrong thing to do: the sysfs files have a lifetime longer than the data structure that is backing it up. I think that sysfs files creation should be moved to the end of probe_thermostat() and sysfs files removal should be moved to the beginning of remove_thermostat().

* PM / Hibernate: Fix preallocating of memoryRafael J. Wysocki2010-03-15
| | | | | | | | | | | | | | | | | | | | | | | commit a9c9b4429df437982d2fbfab1f4b46b01329e9ed upstream. The hibernate memory preallocation code allocates memory to push some user space data out of physical RAM, so that the hibernation image is not too large. It allocates more memory than necessary for creating the image, so it has to release some pages to make room for allocations made while suspending devices and disabling nonboot CPUs, or the system will hang due to the lack of free pages to allocate from. Unfortunately, the function used for freeing these pages, free_unnecessary_pages(), contains a bug that prevents it from doing the job on all systems without highmem. Fix this problem, which is a regression from the 2.6.30 kernel, by using the right condition for the termination of the loop in free_unnecessary_pages(). Signed-off-by: Rafael J.

ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation has a bug that causes endless loop when Payload Pointer of MPEG2-TS frame is 182 or 183. Anyone who sends malicious MPEG2-TS frame will cause the receiver of ULE SNDU to go into endless loop. This patch was generated and tested against linux-2.6.32.9 and should apply cleanly to linux-2.6.33 as well because there was only one typo fix to dvb_net.c since v2.6.32. This bug was brought to you by modern day Santa Claus who decided to shower the satellite dish at Keio University with heavy snow causing huge burst of errors. We, receiver end, received Santa Claus's gift in the form of kernel bug.

* clocksource: Fix up a registration/IRQ race in the sh drivers.Paul Mundt2010-03-15
| | | | | | | | | | | | | | | | | | | | | commit da64c2a8dee66ca03f4f3e15d84be7bedf73db3d upstream. All of the SH clocksource drivers follow the scheme that the IRQ is setup prior to registering the clockevent. The interrupt handler in the clockevent cases looks to the event handler function pointer being filled in by the registration code, permitting us to get in to situations where asserted IRQs step in to the handler before registration has had a chance to complete and hitting a NULL pointer deref. In practice this is not an issue for most platforms, but some of them with fairly special loaders (or that are chain-loading from another kernel) may enter in to this situation. This fixes up the oops reported by Rafael on hp6xx.

The following write hits some variable near to pci_mmcfg_list. Further down a similar problem exists, where cfg->list.next is dereferenced unconditionally and a comparison with some variable near to pci_mmcfg_list happens. Add a check for the last element into the for_each_entry() loop and remove all the other crappy logic which is just a leftover of the old array based code which was replaced by the list conversion.

Namely, the cure is that if the camera is an mr97310a CIF type 1 camera, you have to send it 0xa0, 0x00. Somehow, this is a timing reset command, or such. It un-blocks whatever was previously stopping the CIF type 1 cameras from working on the UHCI-based machines.

* readahead: introduce FMODE_RANDOM for POSIX_FADV_RANDOMWu Fengguang2010-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 0141450f66c3c12a3aaa869748caa64241885cdf upstream. This fixes inefficient page-by-page reads on POSIX_FADV_RANDOM. POSIX_FADV_RANDOM used to set ra_pages=0, which leads to poor performance: a 16K read will be carried out in 4 _sync_ 1-page reads. In other places, ra_pages==0 means - it's ramfs/tmpfs/hugetlbfs/sysfs/configfs - some IO error happened where multi-page read IO won't help or should be avoided. POSIX_FADV_RANDOM actually want a different semantics: to disable the *heuristic* readahead algorithm, and to use a dumb one which faithfully submit read IO for whatever application requests. So introduce a flag FMODE_RANDOM for POSIX_FADV_RANDOM. Note that the random hint is not likely to help random reads performance noticeably. And it may be too permissive on huge request size (its IO size is not limited by read_ahead_kb). In Quentin's report (http://lkml.org/lkml/2009/12/24/145), the overall (NFS read) performance of the application increased by 313%!

* mpt2sas: Delete volume before HBA detach.Kashyap, Desai2010-03-15
| | | | | | | | | | | | | | | | | | commit d7384b28afb2bf2b7be835ddc8c852bdc5e0ce1c upstream. The driver hangs when doing `rmmod mpt2sas` if there are any IR volumes present.The hang is due the scsi midlayer trying to access the IR volumes after the driver releases controller resources. Perhaps when scsi_remove_host is called,the scsi mid layer is sending some request. This doesn't occur for bare drives becuase the driver is already reporting those drives deleted prior to calling mpt2sas_base_detach. To solve this issue, we need to delete the volumes as well.

| | | | | | | | | | | | | | | | | | | commit f09c256375c7cf1e112b8ef6306cdd313490d7c0 upstream. Patch prevents call set_wep_key() with zero key length. That fix long standing regression since commit c0380693520b1a1e4f756799a0edc379378b462a "airo: clean up WEP key operations". Additionally print call trace when someone will try to use improper parameters, and remove key.len = 0 assignment, because it is in not possible code path.

* PCI hotplug: ibmphp: read the length of ebda and map entire ebda regionChandru2010-03-15
| | | | | | | | | | | | | | | | commit b0fc889c4311835ae7d02f433154bc20cad9ee11 upstream. ibmphp driver currently maps only 1KB of ebda memory area into kernel address space during driver initialization. This causes kernel oops when the driver is modprobe'd and it accesses memory beyond 1KB within ebda segment. The first byte of ebda segment actually stores the length of the ebda region in Kilobytes. Hence make use of the length parameter and map the entire ebda region.

* netlabel: fix export of SELinux categories > 127Joshua Roys2010-03-15
| | | | | | | | | | | | | | | | commit c36f74e67fa12202dbcb4ad92c5ac844f9d36b98 upstream. This fixes corrupted CIPSO packets when SELinux categories greater than 127 are used. The bug occured on the second (and later) loops through the while; the inner for loop through the ebitmap->maps array used the same index as the NetLabel catmap->bitmap array, even though the NetLabel bitmap is twice as long as the SELinux bitmap.

* ahci: disable FPDMA auto-activate optimization on NVIDIA AHCIRobert Hancock2010-03-15
| | | | | | | | | | | | | | | | | | | | | | commit 453d3131ec7aab82eaaa8401a50522a337092aa8 upstream. Mike Cui reported that his system with an NVIDIA MCP79 (aka MCP7A) chipset stopped working with 2.6.32. The problem appears to be that 2.6.32 now enables the FPDMA auto-activate optimization in the ahci driver. The drive works fine with this enabled on an Intel AHCI so this appears to be a chipset bug. Since MCP79 is a fairly recent NVIDIA chipset and we don't have any info on whether any other NVIDIA chipsets have this issue, disable FPDMA AA optimization on all NVIDIA AHCI controllers for now.

| * | net: bug fix for vlan + gro issueAjit Khaparde2010-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.
