* Resurrect amd64 support.bschmidt2010-11-224-8/+95
| | | | | | | | | | | | - Many drivers on amd64 are picking system uptime, interrupt time and ticks via global data structure instead of calling functions for performance reasons. For now just patch such address so driver will not trigger page fault when trying to access such data. In future, additional callout may be added to update data in periodic intervals. - On amd64 we need to allocate "shadow space" on stack before calling any function.

* Add the ability for GDB to printout the thread name along with otherattilio2010-11-221-0/+5
| | | | | | | | | | | | | | | | | | | | thread specific informations. In order to do that, and in order to avoid KBI breakage with existing infrastructure the following semantic is implemented: - For live programs, a new member to the PT_LWPINFO is added (pl_tdname) - For cores, a new ELF note is added (NT_THRMISC) that can be used for storing thread specific, miscellaneous, informations. Right now it is just popluated with a thread name. GDB, then, retrieves the correct informations from the corefile via the BFD interface, as it groks the ELF notes and create appropriate pseudo-sections.

| | | | | | | | | | | | | | | | | | | | | | | | | | on FreeBSD (amd64), invocations of "javac" (or "java") eventually end with the output of "Killed" and exit code 137. This is caused by: 1. After calling exec() in multithreaded linux program threads are not destroyed and continue running. They get killed after program being executed finishes. 2. linux_exit_group doesn't return correct exit code when called not from group leader. Which happens regularly using sun jvm. The submitters fix this in a similar way to how NetBSD handles this. I took the PRs away from dchagin, who seems to be out of touch of this since a while (no response from him). The patches committed here are from [2], with some little modifications from me to the style.

* Fix a panic on i386 for drivers using MmAllocateContiguousMemory()bschmidt2010-11-171-2/+2
| | | | | | | | | | | | and MmAllocateContiguousMemorySpecifyCache(). Those two functions take 64-bit variable(s) for their arguments. On i386 that takes additional 32-bit variable per argument. This is required so that windrv_wrap() can correctly wrap function that miniport driver calls with stdcall convention. Similar explanation is provided in subr_ndis.c for other functions.
