* [PATCH] FUTEX_WAKE_OP: enhanced error handlingDavid Gibson2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | The code for FUTEX_WAKE_OP calls an arch callback, futex_atomic_op_inuser(). That callback can return an error code, but currently the caller assumes any error is EFAULT, and will try various things to resolve the fault before eventually giving up with EFAULT (regardless of the original error code). This is not a theoretical case - arch callbacks currently return -ENOSYS if the opcode they are given is bogus. This patch alters the code to detect non-EFAULT errors and return them directly to the user. Of course, whether -ENOSYS is the correct return value for the bogus opcode case, or whether EINVAL would be more appropriate is another question.

* [PATCH] aio: remove aio_max_nr accounting raceZach Brown2005-11-07
| | | | | | | | | | | | | | | | | | | | | AIO was adding a new context's max requests to the global total before testing if that resulting total was over the global limit. This let innocent tasks get their new limit tested along with a racing guilty task that was crossing the limit. This serializes the _nr accounting with a spinlock It also switches to using unsigned long for the global totals. Individual contexts are still limited to an unsigned int's worth of requests by the syscall interface. The problem and fix were verified with a simple program that spun creating and destroying a context while holding on to another long lived context. Before the patch a task creating a tiny context could get a spurious EAGAIN if it raced with a task creating a very large context that overran the limit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | driver_unregister is not being properly called when the init function returns an error case. Restructured the return logic such that this and the other cleanups all happen in one place. Preformed many of the cleanups that Andrew Morton's patch on Thursday made in tpm_atmel.c. Fixed Matthieu's concern about writing before discovery. (akpm: rmk said: This driver is buggy. You must not provide your own release function - it doesn't solve the problem which the warning (which you get when you don't provide one) is telling you about. You should convert your device driver over to the replacement dynamic platform support, once it is merged. IOW, something like: pdev = platform_device_alloc("mydev", id); if (pdev) { err = platform_device_add_resources(pdev, &resources, ARRAY_SIZE(resources)); if (err == 0) err = platform_device_add_data(pdev, &platform_data, sizeof(platform_data)); if (err == 0) err = platform_device_add(pdev); } else { err = -ENOMEM; } if (err) platform_device_put(pdev); ) Signed-off-by: Kylene Jo Hall <kjhall@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

To make pagex and the syscall speedup code work together we would have to add code to the program check handler to do a critical section cleanup like the asynchronous interrupt code. This would make program checks slower. Not what we want. Newer versions of z/VM have the improved pfault pseudo page fault interface. This replaces the old pagex interface and does not have the problem. So its better to just rip out the pagex code.

* [PATCH] uml: big memory fixesJeff Dike2005-11-07
| | | | | | | | | | | | | | | A number of fixes to improve behavior when large physical memory sizes are specified: - libc files need -D_FILE_OFFSET_BITS=64 because there are unavoidable uses of non-64 interfaces in libc - some %d need to be %u Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] uml: maintain own LDT entriesBodo Stroesser2005-11-07
| | | | | | | | | | | | | | | | | | | | Patch imlements full LDT handling in SKAS: * UML holds it's own LDT table, used to deliver data on modify_ldt(READ) * UML disables the default_ldt, inherited from the host (SKAS3) or resets LDT entries, set by host's clib and inherited in SKAS0 * A new global variable skas_needs_stub is inserted, that can be used to decide, whether stub-pages must be supported or not. * Uses the syscall-stub to replace missing PTRACE_LDT (therefore, write_ldt_entry needs to be modified) Signed-off-by: Bodo Stroesser <bstroesser@fujitsu-siemens.com> Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] uml: switch_mm fixBen Lahaise2005-11-07
| | | | | | | | | | | | | Not quite, something along the lines of the patch below works correctly (and makes aio performance not suffer from multiple second delays), as skas0 mode correctly switches mm contexts, unlike TT (which should probably get nuked from the kernel now that skas0 seems to be working).
