| * [IA64] Fix large MCA bootmem allocationRuss Anderson2008-02-081-29/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The MCA code allocates bootmem memory for NR_CPUS, regardless of how many cpus the system actually has. This change allocates memory only for cpus that actually exist. On my test system with NR_CPUS = 1024, reserved memory was reduced by 130944k. Before: Memory: 27886976k/28111168k available (8282k code, 242304k reserved, 5928k data, 1792k init) After: Memory: 28017920k/28111168k available (8282k code, 111360k reserved, 5928k data, 1792k init) Signed-off-by: Russ Anderson <rja@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | When attaching to a stopped process, the RSE must be explicitly synced to user-space, so the debugger can read the correct values. Signed-off-by: Petr Tesarik <ptesarik@suse.cz> CC: Roland McGrath <roland@redhat.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * [IA64] Synchronize kernel RSE to user-space and backPetr Tesarik2008-02-082-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is base kernel patch for ptrace RSE bug. It's basically a backport from the utrace RSE patch I sent out several weeks ago. please review. when a thread is stopped (ptraced), debugger might change thread's user stack (change memory directly), and we must avoid the RSE stored in kernel to override user stack (user space's RSE is newer than kernel's in the case). To workaround the issue, we copy kernel RSE to user RSE before the task is stopped, so user RSE has updated data. we then copy user RSE to kernel after the task is resummed from traced stop and kernel will use the newer RSE to return to user.

| * [IA64] Rename TIF_PERFMON_WORK back to TIF_NOTIFY_RESUMEPetr Tesarik2008-02-082-18/+12
| | | | | | | | | | | | | | | | | | | | | | Since the RSE synchronization will need a TIF_ flag, but all work-to-be-done bits are already used, so we have to multiplex TIF_NOTIFY_RESUME again.

* | [Blackfin] arch: move the init sections to the end of memoryMike Frysinger2008-02-023-27/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the init sections to the end of memory so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob.

| | | | | | | | | | | | | | | | | | | | | - Change spin_lock + local_irq_save into spin_lock_irqsave - Change spin_unlock + local_irq_restore into spin_unlock_irqrestore - Return ENOTTY if ioctl is not recognized as a cris ioctl. - Make init functions static.
| * | CRIS v32: Rewrite ARTPEC-3 gpio driver to avoid volatiles and general cleanup.Jesper Nilsson2008-02-081-174/+174
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes as suggested by Andrew Morton, plus general cleanup to ease later consolidation of driver into machine common driver. - Correct parameter type of gpio_write to const char __user * - Remove volatile from the arrays of machine dependent registers, use readl and writel to access them instead. - Remove useless casts of void. - Use spin_lock_irqsave for locking. - Break gpio_write into smaller sub-functions. - Remove useless breaks after returns. - Don't perform any change in IO_CFG_WRITE_MODE if values are invalid. (previously values were set and then set to zero) - Change cast for copy_to_user to (void __user *) - Make file_operations gpio_fops static and const. - Make setget_output static. (However, it's still inline since the CRIS architecture is still not SMP, which makes the function small enough to inline)
