* sparc: Fix fork/clone/vfork system call restart.David S. Miller2008-05-07
| | | | | | | | | | | | | We clobber %i1 as well as %i0 for these system calls, because they give two return values. Therefore, on error, we have to restore %i1 properly or else the restart explodes since it uses the wrong arguments. This fixes glibc's nptl/tst-eintr1.c testcase. Signed-off-by: David S.

* unified (weak) sys_pipe implementationUlrich Drepper2008-05-03
| | | | | | | | | | | | | | | | | | | This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | The PROM library function prom_meminit() builds a table, prom_phys_avail[], just so that probe_memory() in arch/sparc/mm/fault.c can copy it into sp_banks[].

| * sparc32: Kill totally unused memory information tables.David S. Miller2008-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | The code in arch/sparc/prom/memory.c computes three tables, the list of total memory, the list of available memory (total minus what firmware is using), and the list of firmware taken memory. Only the available memory list is even used. Therefore, kill those unused tables and make prom_meminfo() return just the available memory list. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc64: Fix syscall restart, for real...David S. Miller2008-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change I put into copy_thread() just papered over the real problem. When we are looking to see if we should do a syscall restart, when deliverying a signal, we should only interpret the syscall return value as an error if the carry condition code(s) are set. Otherwise it's a success return. Also, sigreturn paths should do a pt_regs_clear_trap_type(). It turns out that doing a syscall restart when returning from a fork() does and should happen, from time to time. Even if copy_thread() returns success, copy_process() can still unwind and signal -ERESTARTNOINTR in the parent. Signed-off-by: David S. Miller <davem@davemloft.net>

| * | [POWERPC] Bolt in SLB entry for kernel stack on secondary cpusPaul Mackerras2008-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression reported by Kamalesh Bulabel where a POWER4 machine would crash because of an SLB miss at a point where the SLB miss exception was unrecoverable. This regression is tracked at: http://bugzilla.kernel.org/show_bug.cgi?id=10082 SLB misses at such points shouldn't happen because the kernel stack is the only memory accessed other than things in the first segment of the linear mapping (which is mapped at all times by entry 0 of the SLB). The context switch code ensures that SLB entry 2 covers the kernel stack, if it is not already covered by entry 0. None of entries 0 to 2 are ever replaced by the SLB miss handler. Where this went wrong is that the context switch code assumes it doesn't have to write to SLB entry 2 if the new kernel stack is in the same segment as the old kernel stack, since entry 2 should already be correct. However, when we start up a secondary cpu, it calls slb_initialize, which doesn't set up entry 2. This is correct for the boot cpu, where we will be using a stack in the kernel BSS at this point (i.e. init_thread_union), but not necessarily for secondary cpus, whose initial stack can be allocated anywhere. This doesn't cause any immediate problem since the SLB miss handler will just create an SLB entry somewhere else to cover the initial stack. In fact it's possible for the cpu to go quite a long time without SLB entry 2 being valid. Eventually, though, the entry created by the SLB miss handler will get overwritten by some other entry, and if the next access to the stack is at an unrecoverable point, we get the crash. This fixes the problem by making slb_initialize create a suitable entry for the kernel stack, if we are on a secondary cpu and the stack isn't covered by SLB entry 0. This requires initializing the get_paca()->kstack field earlier, so I do that in smp_create_idle where the current field is initialized. This also abstracts a bit of the computation that mk_esid_data in slb.c does so that it can be used in slb_initialize. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the subject says this patch adds the support for kernel preemption on m68knommu Coldfire. I thing the same changes could be applied to 68360 & 68328 but since I don't have the HW for testing, I don't touch it.

* | | | | m68knommu: fix signal handling return pathWilson Callan2008-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The return from software signal handling pushes code on the stack that system calls to the kernels cleanup code. This is borrowed directly from the m68k linux signal handler. The rt signal case is not quite right for the restricted instruction set of the ColdFire parts. And neither the normal signal case or rt signal case properly flushes/pushes the appropriate cache lines. Rework the return path to just call back through some code fragments in the kernel proper (with no MMU in the way we can do this). No cache problems, and less code overall. Original patch submitted by Wilson Callan <wcallan@savantav.com> Greg fixed the rt signal return path to use the proper system call Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | | | | ntp: rename TICK_LENGTH_SHIFT to NTP_SCALE_SHIFTRoman Zippel2008-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As TICK_LENGTH_SHIFT is used for more than just the tick length, the name isn't quite approriate anymore, so this renames it to NTP_SCALE_SHIFT.
