2010-12-07perf makefile: Allow strong and weak functions in LIB_OBJSIan Munsie
When we build perf we place all of the .o files from the library files (util, arch/x/util, etc) into libperf.a which is then linked into perf. The problem is that the linker will by default only consider .o files within the .a archive if they are necessary to satisfy an unresolved symbol. As weak functions are not unresolved, it will not consider a .o file from the archive containing the strong versions of weak functions unless it requires it for another reason. This patch adds the --whole-archive flags to the linker when passing in the libperf.a file to ensure that it will consider every .o file in the archive, not just what it believes that it needs. The end result is that weak functions can now be overridden by strong variants of them in the libperf.a file.

2010-12-07drm/i915: Emit a request to clear a flushed and idle ring for unbusy boChris Wilson
In order for bos to retire eventually, a request must be sent down the ring. This is expected, for example, by occlusion queries for which mesa will wait upon (whilst running glean) before issuing more batches and so the normal activity upon the ring is suspended and we need to emit a request to clear the idle ring.

2010-12-06PM / Hibernate: Fix memory corruption related to swapRafael J. Wysocki
There is a problem that swap pages allocated before the creation of a hibernation image can be released and used for storing the contents of different memory pages while the image is being saved. Since the kernel stored in the image doesn't know of that, it causes memory corruption to occur after resume from hibernation, especially on systems with relatively small RAM that need to swap often. This issue can be addressed by keeping the GFP_IOFS bits clear in gfp_allowed_mask during the entire hibernation, including the saving of the image, until the system is finally turned off or the hibernation is aborted. Unfortunately, for this purpose it's necessary to rework the way in which the hibernate and suspend code manipulates gfp_allowed_mask. This change is based on an earlier patch from Hugh Dickins.

2010-12-06PM / Hibernate: Use async I/O when reading compressed hibernation imageBojan Smojver
This is a fix for reading LZO compressed image using async I/O. Essentially, instead of having just one page into which we keep reading blocks from swap, we allocate enough of them to cover the largest compressed size and then let block I/O pick them all up. Once we have them all (and here we wait), we decompress them, as usual. Obviously, the very first block we still pick up synchronously, because we need to know the size of the lot before we pick up the rest. Also fixed the copyright line, which I've forgotten before.

The right function is memcmp, which is also used in another section of wmi code. It was finding 49142400-C6A3-40FA-BADB-8A2652834100 as a duplicate of 39142400-C6A3-40FA-BADB-8A2652834100.

This patch enables the UART on the CE4100. The UART has a couple of issues that need to be worked around. First the UART is mostly PC compatible except that it is clocked eight times faster than a standard PC so the default configuration provided in arch/x86/include/asm/serial.h needs to be overridden. Second the TX interrupt may not be set correctly all the time. Lastly accessing the UART via I/O space for early_prink() hangs the chip when the IOAPIC is enabled. A custom mem_serial_in() is provided to work around the TX interrupt issue.

2010-12-06perf session: Sort all events if ordered_samples=trueThomas Gleixner
Now that we have timestamps on FORK, EXIT, COMM, MMAP events we can sort everything in time order. This fixes the following observed problem: mmap(file1) -> pagefault() -> munmap(file1) mmap(file2) -> pagefault() -> munmap(file2) Resulted in decoding both pagefaults in file2 because the file1 map was already replaced by the file2 map when the map address was identical. With all events sorted we decode both pagefaults correctly.

2010-12-06perf hist: Better displaying of unresolved DSOs and symbolsIan Munsie
In the event that a DSO has not been identified, just print out [unknown] instead of the instruction pointer as we previously were doing, which is pretty meaningless for a shared object (at least to the users perspective). The IP we print out is fairly meaningless in general anyway - it's just one (the first) of the many addresses that were lumped together as unidentified, and could span many shared objects and symbols. In reality if we see this [unknown] output then the report -D output is going to be more useful anyway as we can see all the different address that it represents. If we are printing the symbols we are still going to see this IP in that column anyway since they shouldn't resolve either. This patch also changes the symbol address printouts so that they print out 0x before the address, are left aligned, and changes the %L format string (which relies on a glibc bug) to %ll.

2010-12-06x86: io_apic: Split setup_ioapic_ids_from_mpc()Sebastian Andrzej Siewior
Sodaville needs to setup the IO_APIC ids as the boot loader leaves them uninitialized. Split out the setter function so it can be called unconditionally from the sodaville board code.
