* uml: use UM_THREAD_SIZE in userspace codeJeff Dike2007-05-112-6/+4
| | | | | | | | | | | Now that we have UM_THREAD_SIZE, we can replace the calculations in user-space code (an earlier patch took care of the kernel side of the house).

* uml: remove task_protectionsJeff Dike2007-05-116-24/+8
| | | | | | | | | | | | | | Replaced task_protections with stack_protections since they do the same thing, and task_protections was misnamed anyway. This needs THREAD_SIZE, so that's imported via common-offsets.h Also tidied up the code in the vicinity.

| | | | | | | | | | | | Fix the tlb-miss handler (tme_handler) to check _PAGE_PRESENT bit in order to handle file-mapped or swapped-out pages correctly. This patch is required to fix unexpected page errors for m32r.

* m32r: fix switch_to macro to push/pop frame pointer if neededHirokazu Takata2007-05-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a rarely-happened but severe scheduling problem of the recent m32r kernel of 2.6.17-rc3 or later. In the following previous m32r patch, the switch_to macro was modified not to do unnecessary push/pop operations for tuning. > [PATCH] m32r: update switch_to macro for tuning > 4127272c38619c56f0c1aa01d01c7bd757db70a1 In this modification, only 'lr' and 'sp' registers are push/pop'ed, assuming that the m32r kernel is always compiled with -fomit-frame-pointer option. However, in 2.6 kernel, kernel/sched.c is irregularly compiled with -fno-omit-frame-pointer if CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER is not defined. -- kernel/Makefile -- : ifneq ($(CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER),y) # According to Alan Modra <alan@linuxcare.com.au>, the -fno-omit-frame-pointer is # needed for x86 only. Why this used to be enabled for all architectures is beyond # me. I suspect most platforms don't need this, but until we know that for sure # I turn this off for IA-64 only. Andreas Schwab says it's also needed on m68k # to get a correct value for the wait-channel (WCHAN in ps). --davidm CFLAGS_sched.o := $(PROFILING) -fno-omit-frame-pointer endif : --- Therefore, for the recent m32r kernel, we have to push/pop 'fp' (frame pointer) if CONFIG_FRAME_POINTER is defined or CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER is not defined.

* x86_64: display more intuitive error message if kernel is not 2MB alignedVivek Goyal2007-05-111-7/+0
| | | | | | | | | | | | | | | | | | | o x86_64 kernel needs to be compiled for 2MB aligned addresses. Currently we are using BUILD_BUG_ON() to warn the user if he has not done so. But looks like folks are not finding message very intutive and don't open the respective c file to find problem source.

| * [POWERPC] Fix compile error with kexec and CONFIG_SMP=nPaul Mackerras2007-05-101-0/+1
| | | | | | | | | | | | | | | | | | | | Commit 2f4dfe206a2fc07099dfad77a8ea2f4b4ae2140f moved the definition of hard_smp_processor_id() for the UP case from include/linux/smp.h to include/asm/smp.h. However, include/linux/smp.h only includes include/asm/smp.h in the SMP case, so code that wants to use hard_smp_processor_id() has to include <asm/smp.h> explicitly to be sure of getting the definition.

| | | | | | | | | | | | | | | | | | | | | | | | | | If CONFIG_BLK_DEV_INITRD is not defined the prop variable in early_init_dt_scan_chosen() is unused, causing a compiler warning.

| * [POWERPC] Fix incorrect calculation of I/O window addressesPaul Mackerras2007-05-101-24/+13
| | | | | | | | | | | | | | | | | | | | | | | | My patch "Cope with PCI host bridge I/O window not starting at 0" introduced a bug in the calculation of the virtual addresses for the I/O windows of PCI host bridges other than the first, because it didn't account for the fact that hose->io_resource gets offset so that it reflects the range of global I/O port numbers assigned to the bridge. This fixes it and simplifies get_bus_io_range() in the process. Signed-off-by: Paul Mackerras <paulus@samba.org>

But newer boot logic gives same bus ID between PHBs (it gives bus ID 0 as root bus.) So we have to set 'phb->buid' as non-zero.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

Entering the kernel at startup_32 without passing our real mode data in %esi, and without guaranteeing that physical and virtual addresses are identity mapped makes head.S impossible to maintain. The only user of this infrastructure is lguest which is not merged so nothing we currently support will break by removing this over designed nightmare, and only the pending lguest patches will be affected. The pending Xen patches have a different entry point that they use. We are currently discussing what Xen and lguest need to do to boot the kernel in a more normal fashion so using startup_32 in this weird manner is clearly not their long term direction. So let's remove this code in head.S before it causes brain damage to people trying to maintain head.S Cc: Chris Wright <chrisw@sous-sol.org> Cc: Andi Kleen <ak@suse.de> Cc: Jeremy Fitzhardinge <jeremy@goop.org> Cc: Zachary Amsden <zach@vmware.com> CC: H.

Big problem for checkpoint/restore, because all the stopped/traced processes are born in this state, hence they cannot be checkpointed again due to failing unwind. The problem was identified as assumption in kernel unwind library that top level frame is different of syscall frame. It is the case unless process was born with CLONE_STOPPED.

| * | | [IA64] fix stack alignment for ia32 signal handlersMarkus F.X.J. Oberhumer2007-05-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the setup of the alignment of the signal frame, so that all signal handlers are run with a properly aligned stack frame. The current code "over-aligns" the stack pointer so that the stack frame is effectively always mis-aligned by 4 bytes. But what we really want is that on function entry ((sp + 4) & 15) == 0, which matches what would happen if the stack were aligned before a "call" instruction. i386 and x86_64 are already fixed by d347f372273c2b3d86a66e2e1c94c790c208e166 Signed-off-by: Markus F.X.J.

| * | | [IA64] - Altix: hotplug after intr redirect can crash systemJohn Keller2007-05-081-15/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When redirecting a device interrupt on SN, not all links between platform specific structures are being updated. This can result in a system crash if an interrupt redirection is followed by an unplug of that device. The complete fix also requires a prom update. Though, this patch is backward compatable and not dependent on the prom patch. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
