* Use i8253.c lock for PC speaker on MIPS, too.Ralf Baechle2007-11-021-1/+1
| | | | | | | | | | The Jazz machines have to use the PIT timer for dyntick and highresolution kernels. This may break because currently just like i386 used to do MIPS uses two separate spinlocks in the actual PIT code and the PC speaker code. So switch to do it the same that x86 currently does PIT locking. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* [MIPS] Add len and addr validation for MAP_FIXED mappings.David Daney2007-10-291-2/+7
| | | | | | | | | | | | | | | | | | Mmap with MAP_FIXED was not validating the addr and len parameters. This leads to the failure of GCC's gcc.c-torture/execute/loop-2[fg].c testcases when using the o32 ABI on a 64 bit kernel. These testcases try to mmap 65536 bytes at 0x7fff8000 and then access all the memory. In 2.6.18 and 2.6.23.1 (and likely other versions as well) the kernel maps the requested memory, but since half of it is above 0x80000000 a SIGBUS is generated when it is accessed. This patch moves the len validation above the MAP_FIXED processing so that it is always validated. It also adds validation to the addr parameter for MAP_FIXED mappings.

* [MIPS] SMTC: Allow control over TC assignment to vpe0.Kevin D. Kissell2007-10-291-13/+44
| | | | | | | | | | | | | | | | | Modify the SMTC initialization code to allow boot-time specification not only of how many VPEs and TCs to use, but also how many TCs out of the allowed pool are to be bound to VPE 0. The new boot option is "vpe0tcs=N", where N is an integer. Using it in combination with the existing options allows arbitrary assignments across the 2 VPEs of a 34K. e.g. "maxtcs=3 vpe0tcs=1" forces VPE0 to have 1 TC, while VPE1 has 2, and "maxtcs=4 vpe0tcs=3" forces VPE0 to have 3 TCs, while VPE1 gets 1. If no vpe0tcs option is specified, the traditional algorithm of evenly dividing TCs between available VPEs, with the odd "slop" going to VPE0, is retained. The reason for doing this is to allow a finer balancing of TCs which can handle I/O interrupts on Malta (those on VPE 0) and those which cannot. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

The proposals are to * equip the functions that return the integer with _nr suffix to represent that fact, * and to make all functions work with task (not process) by making the common prefix of the same name. For monotony the routines signal_session() and set_signal_session() are replaced with task_session_nr() and set_task_session(), especially since they are only used with the explicit task->signal dereference.

* [MIPS] SYNC emulation for MIPS I processorsMaciej W. Rozycki2007-10-171-78/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Userland, including the C library and the dynamic linker, is keen to use the SYNC instruction, even for "generic" MIPS I binaries these days. Which makes it less than useful on MIPS I processors. This change adds the emulation, but as our do_ri() infrastructure was not really prepared to take yet another instruction, I have rewritten it and its callees slightly as follows. Now there is only a single place a possible signal is thrown from. The place is at the end of do_ri(). The instruction word is fetched in do_ri() and passed down to handlers. The handlers are called in sequence and return a result that lets the caller decide upon further processing. If the result is positive, then the handler has picked the instruction, but a signal should be thrown and the result is the signal number. If the result is zero, then the handler has successfully simulated the instruction. If the result is negative, then the handler did not handle the instruction; to make it more obvious the calls do not follow the usual 0/-Exxx result convention they now return -1 instead of -EFAULT. The calculation of the return EPC is now at the beginning. The reason is it is easier to handle it there as emulation callees may modify a register and an instruction may be located in delay slot of a branch whose result depends on the register. It has to be undone if a signal is to be raised, but it is not a problem as this is the slow-path case, and both actions are done in single places now rather than the former being scattered through emulation handlers. The part of do_cpu() being covered follows the changes to do_ri(). Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> ---

* core_pattern: ignore RLIMIT_CORE if core_pattern is a pipeNeil Horman2007-10-171-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some time /proc/sys/kernel/core_pattern has been able to set its output destination as a pipe, allowing a user space helper to receive and intellegently process a core. This infrastructure however has some shortcommings which can be enhanced. Specifically: 1) The coredump code in the kernel should ignore RLIMIT_CORE limitation when core_pattern is a pipe, since file system resources are not being consumed in this case, unless the user application wishes to save the core, at which point the app is restricted by usual file system limits and restrictions. 2) The core_pattern code should be able to parse and pass options to the user space helper as an argv array. The real core limit of the uid of the crashing proces should also be passable to the user space helper (since it is overridden to zero when called). 3) Some miscellaneous bugs need to be cleaned up (specifically the recognition of a recursive core dump, should the user mode helper itself crash. Also, the core dump code in the kernel should not wait for the user mode helper to exit, since the same context is responsible for writing to the pipe, and a read of the pipe by the user mode helper will result in a deadlock. This patch: Remove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that core_pattern is a pipe, the entire core will be fed to the user mode helper.
