* [S390] Fix init irq proc build break.Sachin Sant2009-02-11

| | | | | | | | | The vdso_per_cpu_data entry in the lowcore structure uses __u32 instead of __u64. If the data page is above 4GB the pointer is truncated and the kernel crashes. Reported-by: Mijo Safradin <mijo@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| * powerpc: Add missing sparsemem.h includeMichael Neuling2009-02-09
| | | | | | | | | | | | | | | | | | arch/powerpc/platforms/pseries/hotplug-memory.c uses remove_section_mapping() but doesn't include sparsemem.h which defines it.

| * powerpc/pci: mmap anonymous memory when legacy_mem doesn't existBenjamin Herrenschmidt2009-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new legacy_mem file in sysfs is causing problems with X on machines that don't support legacy memory access. The way I initially implemented it, we would fail with -ENXIO when trying to mmap it, thus exposing to X that we do support the API but there is no legacy memory. Unfortunately, X poor error handling is causing it to fail to start when it gets this error. This implements a workaround hack that instead maps anonymous memory instead (using shmem if VM_SHARED is set, just like /dev/zero does).

From Chris's report: -------------------- This came up in testing kgdb, using the built-in tests -- turn on CONFIG_KGDB_TESTS, then echo V1 > /sys/module/kgdbts/parameters/kgdbts -- but it would affect using kgdb if you were debugging and looking at bad pointers. -------------------- When we get a copy_{from,to}_user() request and the %asi is set to something other than ASI_AIUS (which is userspace) then we branch off to a routine called memcpy_user_stub(). It just does a straight memcpy since we are copying from kernel to kernel in this case. The logic was that since source and destination are both kernel pointers we don't need to have exception checks. But for what probe_kernel_{read,write}() is trying to do, we have to have the checks, otherwise things like kgdb bad kernel pointer accesses don't do the right thing. Signed-off-by: David S.

At the cost of one symbol in copy_in_user.S, you could just have one common two-instruction retl-and-mov-1 fixup that they all share. -------------------- The following is with a defconfig build: text data bss dec hex filename 3972767 344024 584449 4901240 4ac978 vmlinux.orig 3968887 344024 584449 4897360 4aba50 vmlinux Signed-off-by: David S.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At this time, the PowerNow! driver for K8 uses an experimentally derived formula to calculate transition latency. The value it provides is orders of magnitude too large on modern systems. This patch replaces the formula with ACPI _PSS latency values for more accuracy and better performance.

When using 32-bit "int $0x80" entry for a bogus syscall number, the return value is not correctly set to -ENOSYS. This only happens when neither syscall-audit nor syscall tracing is enabled (i.e., never seen if auditd ever started). Test program: /* gcc -o int80-badsys -m32 -g int80-badsys.c Run on x86-64 kernel. Note to reproduce the bug you need auditd never to have started. */ #include <errno.h> #include <stdio.h> int main (void) { long res; asm ("int $0x80" : "=a" (res) : "0" (99999)); printf ("bad syscall returns %ld\n", res); return res != -ENOSYS; } The fix makes the int $0x80 path match the sysenter and syscall paths.

Fix that by falling back to the default APIC base address in 32bit code, as it is done in the 64bit codepath. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Signed-off-by: H.

Most of these changes are obsolete as the subarch code has been removed from the x86 development tree - but we merge them upstream to make Voyager build and boot. ] Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
