2012-01-23ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMPWill Deacon
It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

2012-01-23ARM: 7291/1: cache: assume 64-byte L1 cachelines for ARMv7 CPUsWill Deacon
To ensure correct alignment of cacheline-aligned data, the maximum cacheline size needs to be known at compile time. Since Cortex-A8 and Cortex-A15 have 64-byte cachelines (and it is likely that there will be future ARMv7 implementations with the same line size) then it makes sense to assume that CPU_V7 implies a 64-byte L1 cacheline size. For CPUs with smaller caches, this will result in some harmless padding but will help with single zImage work and avoid hitting subtle bugs with misaligned data structures.

2012-01-23ARM: 7290/1: vmlinux.lds.S: align the exception fixup table to a 4-byte boundaryWill Deacon
The exception fixup table is currently aligned to a 32-byte boundary. Whilst this won't cause any problems, the exception_table_entry structures contain only a pair of unsigned longs, so 4-byte alignment is all that is required. If the table was walked from start to end, cacheline alignment may bring some performance benefits, but since a binary search is used, the access pattern is random and will not benefit from a stricter alignment.

2012-01-23ARM: 7289/1: vmlinux.lds.S: do not hardcode cacheline size as 32 bytesWill Deacon
The linker script assumes a cacheline size of 32 bytes when aligning the .data..cacheline_aligned and .data..percpu sections. This patch updates the script to use L1_CACHE_BYTES, which should be set to 64 on platforms that require it.

2012-01-19ARM: fix rcu stalls on SMP platformsRussell King
We can stall RCU processing on SMP platforms if a CPU sits in its idle loop for a long time.

2012-01-17Kernel: Audit Support For The ARM PlatformNathaniel Husted
This patch provides functionality to audit system call events on the ARM platform. The implementation was based off the structure of the MIPS platform and information in this (http://lists.fedoraproject.org/pipermail/arm/2009-October/000382.html) mailing list thread. The required audit_syscall_exit and audit_syscall_entry checks were added to ptrace using the standard registers for system call values (r0 through r3). A thread information flag was added for auditing (TIF_SYSCALL_AUDIT) and a meta-flag was added (_TIF_SYSCALL_WORK) to simplify modifications to the syscall entry/exit. Now, if either the TRACE flag is set or the AUDIT flag is set, the syscall_trace function will be executed. The prober changes were made to Kconfig to allow CONFIG_AUDITSYSCALL to be enabled. Due to platform availability limitations, this patch was only tested on the Android platform running the modified "android-goldfish-2.6.29" kernel. A test compile was performed using Code Sourcery's cross-compilation toolset and the current linux-3.0 stable kernel. The changes compile without error. I'm hoping, due to the simple modifications, the patch is "obviously correct". Signed-off-by: Nathaniel Husted <nhusted@gmail.com> Signed-off-by: Eric Paris <eparis@redhat.com>
2012-01-17audit: inline audit_syscall_entry to reduce burden on archsEric Paris

2012-01-17audit: ia32entry.S sign extend error codes when calling 64 bit codeEric Paris
In the ia32entry syscall exit audit fastpath we have assembly code which calls __audit_syscall_exit directly. This code was, however, zeroes the upper 32 bits of the return code. It then proceeded to call code which expects longs to be 64bits long. In order to handle code which expects longs to be 64bit we sign extend the return code if that code is an error. Thus the __audit_syscall_exit function can correctly handle using the values in snprintf("%ld"). This fixes the regression introduced in 5cbf1565f29eb57a86a. Old record: type=SYSCALL msg=audit(1306197182.256:281): arch=40000003 syscall=192 success=no exit=4294967283 New record: type=SYSCALL msg=audit(1306197182.256:281): arch=40000003 syscall=192 success=no exit=-13 Signed-off-by: Eric Paris <eparis@redhat.com> Acked-by: H.

2012-01-17Audit: push audit success and retcode into arch ptrace.hEric Paris
The audit system previously expected arches calling to audit_syscall_exit to supply as arguments if the syscall was a success and what the return code was. Audit also provides a helper AUDITSC_RESULT which was supposed to simplify things by converting from negative retcodes to an audit internal magic value stating success or failure. This helper was wrong and could indicate that a valid pointer returned to userspace was a failed syscall. The fix is to fix the layering foolishness. We now pass audit_syscall_exit a struct pt_reg and it in turns calls back into arch code to collect the return value and to determine if the syscall was a success or failure. We also define a generic is_syscall_success() macro which determines success/failure based on if the value is < -MAX_ERRNO. This works for arches like x86 which do not use a separate mechanism to indicate syscall failure. We make both the is_syscall_success() and regs_return_value() static inlines instead of macros. The reason is because the audit function must take a void* for the regs. (uml calls theirs struct uml_pt_regs instead of just struct pt_regs so audit_syscall_exit can't take a struct pt_regs). Since the audit function takes a void* we need to use static inlines to cast it back to the arch correct structure to dereference it. The other major change is that on some arches, like ia64, MIPS and ppc, we change regs_return_value() to give us the negative value on syscall failure. THE only other user of this macro, kretprobe_example.c, won't notice and it makes the value signed consistently for the audit functions across all archs. In arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old audit code as the return value. But the ptrace_64.h code defined the macro regs_return_value() as regs[3]. I have no idea which one is correct, but this patch now uses the regs_return_value() function, so it now uses regs[3]. For powerpc we previously used regs->result but now use the regs_return_value() function which uses regs->gprs[3]. regs->gprs[3] is always positive so the regs_return_value(), much like ia64 makes it negative before calling the audit code when appropriate.

In SRAT v1, we had 8bit proximity domain (PXM) fields; SRAT v2 provides 32bits for these. The new fields were reserved before. According to the ACPI spec, the OS must disregrard reserved fields. ia64 did handle the PXM fields almost consistently, but depending on sgi's sn2 platform. This patch leaves the sn2 logic in, but does also use 16/32 bits for PXM if the SRAT has rev 2 or higher. The patch also adds __init to the two pxm accessor functions, as they access __initdata now and are called from an __init function only anyway. Note that the code only uses 16 bits for the PXM field in the processor proximity field; the patch does not address this as 16 bits are more than enough.

2012-01-17ACPI, Record ACPI NVS regionsHuang Ying
Some firmware will access memory in ACPI NVS region via APEI. That is, instructions in APEI ERST/EINJ table will read/write ACPI NVS region. The original resource conflict checking in APEI code will check memory/ioport accessed by APEI via general resource management mechanism. But ACPI NVS region is marked as busy already, so that the false resource conflict will prevent APEI ERST/EINJ to work. To fix this, this patch record ACPI NVS regions, so that we can avoid request resources for memory region inside it.

2012-01-16mce: fix warning messages about static struct mce_deviceGreg Kroah-Hartman
When suspending, there was a large list of warnings going something like: Device 'machinecheck1' does not have a release() function, it is broken and must be fixed This patch turns the static mce_devices into dynamically allocated, and properly frees them when they are removed from the system. It solves the warning messages on my laptop here. Reported-by: "Srivatsa S.

2012-01-16ARM: OMAP3: fix build on !CONFIG_IOMMU_APIOhad Ben-Cohen
omap3isp depends on CONFIG_IOMMU_API, so avoid registering its device (and defining its configuration structs) on !CONFIG_IOMMU_API. This is generally nice to have, but more importantly, it fixes: arch/arm/plat-omap/include/plat/iommu.h: In function 'dev_to_omap_iommu': arch/arm/plat-omap/include/plat/iommu.h:135: error: 'struct dev_archdata' has no member named 'iommu' arch/arm/mach-omap2/devices.c: In function 'omap3_init_camera': arch/arm/mach-omap2/devices.c:222: error: 'struct dev_archdata' has no member named 'iommu' make[1]: *** [arch/arm/mach-omap2/devices.o] Error 1 make: *** [arch/arm/mach-omap2] Error 2 Which happens because while setting up the omap3isp device we try to access the (now nonexistent) iommu member of dev_archdata.
