* Merge branch 'release' of ↵Linus Torvalds2007-05-224-12/+27
|\ | | | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6: [IA64] fix kmalloc(0) in arch/ia64/pci/pci.c [IA64] Only unwind non-running tasks. [IA64] Improve unwind checking. [IA64] Yet another section mismatch warning [IA64] Fix bogus messages about system calls not implemented.
| * [IA64] fix kmalloc(0) in arch/ia64/pci/pci.cKenji Kaneshige2007-05-221-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Hiroyuki Kamezawa reported the problem that pci_acpi_scan_root() of ia64 might call kmalloc_node() with zero size. Currently ia64's pci_acpi_scan_root() assumes that _CRS method of root bridge has at least one resource window. But, the root bridges that has no resource window must be taken into account.

| * [IA64] Only unwind non-running tasks.Robin Holt2007-05-221-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Unwinding a running task has proven problematic. In one instance, the running task was attempting to unwind itself and received an interrupt between when get_wchan allocated local variables on the stack and when unw_init_from_blocked_task was called which resulted in unw_init_frame_info to place this tasks task_struct pointer over the switch stack's ar_bspstore entry.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sam's recent change in 7664709b44a13e2e0b545e2dd8e7b8797a1748dc broke things for us because we ended up with *(.text.*) before *(.text), whereas previously *(.text) was first. This was important because the start of the text section contains the kernel entry point. In fact, we don't need that *(.text.*) thing anymore and it incorrectly matched .text.init.refok, thus putting it before .text. .. ouch !

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pmc.c has: #ifndef MMCR0_PMA0 #define MMCR0_PMA0 0 This one took a while to find.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently, we check for the minimum ARM architecture that we're building for to determine whether we need ASID support. This is wrong - if we're going to support a range of CPUs which include ARMv6 or higher, we need the ASID.

This however means that there is about a ticks worth of time each second where time() will return a second value less then what gettimeofday() does. Additionally, this window where vtime() is behind vgettimeofday() grows when dynticks is enabled, so its probably good to get this in before dynticks lands. Big thanks to Sripathi for noticing this issue and creating a test case to work with!

* | | Blackfin arch: fix signal handling bugBernd Schmidt2007-05-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a forum thread at https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741 which has a testcase involving signal handling that crashes quite readily. Inspecting the code I believe what happens is that signal handling can become confused when it is invoked on return from an interrupt, if the contents of P0 and R0 at the time of the interrupt happen to be such that P0 is larger than zero (indicating to the signal code that we're in a syscall), and R0 happens to have a value of something like -EINTR or -ERESTARTSYS. Fixed by setting orig_p0 to -1 if we're returning from an interrupt. The testcase now seems to run without problems.
