2023-04-04s390: use init_thread_union aka initial stack for the first processHeiko Carstens
s390 is the only architecture which switches from the initial stack to a later on allocated different stack for the first process. This is (at least) problematic for the stackleak feature, which instruments functions to save the current stackpointer within the task structure of the running process. The stackleak code compares stack pointers of the current process - and doesn't expect that the kernel stack of a task can change. Even though the stackleak feature itself will not cause any harm, the assumption about kernel stacks being consistent is there, and only s390 doesn't follow that. Therefore switch back to use init_thread_union, just like all other architectures.

2023-04-04s390/dumpstack: simplify in stack logic codeHeiko Carstens
The pattern for all in_<type>_stack() functions is the same; especially also the size of all stacks is the same. Simplify the code by passing only the stack address to the generic in_stack() helper, which then can assume a THREAD_SIZE sized stack.

2023-04-04s390: make extables read-onlyVasily Gorbik
Currently, exception tables are marked as ro_after_init. However, since they are sorted during compile time using scripts/sorttable, they can be moved to RO_DATA using the RO_EXCEPTION_TABLE_ALIGN macro, which is specifically designed for this purpose.

2023-04-04s390/entry: rely on long-displacement facilityVasily Gorbik
Since commit 4efd417f298b ("s390: raise minimum supported machine generation to z10"), the long-displacement facility is assumed and required for the kernel. Clean up a couple of places in the entry code, where long-displacement could be used directly instead of using a base register. However, there are still a few other places where a base register has to be used to extend short-displacement for the second lowcore page access. Notably, boot/head.S still has to be built for z900, and in mcck_int_handler, spt and lbear, which don't have long-displacements, but need to access save areas at the second lowcore page.

2023-04-04Merge branch 'uaccess-inline-asm-cleanup' into featuresVasily Gorbik
Heiko Carstens says: =================== There are a couple of oddities within the s390 uaccess library functions. Therefore cleanup the whole uaccess.c file. There is no functional change, only improved readability. The output of "objdump -Dr" was always compared before/after each patch to make sure that the generated object file is identical, if that could be expected. Therefore the series also includes more patches than really required to cleanup the code. Furthermore the kunit usercopy tests also still pass. =================== Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>

2023-04-04s390/uaccess: get rid of not needed local variableHeiko Carstens
Get rid of the not needed val local variable and pass the constant value directly as operand value. In addition this turns the val operand into an input operand, since it is not changed within the inline assemblies. This in turn requires also to add the earlyclobber contraint modifier to all output operands, since the (former) val operand is used after all output variants have been modified. The usercopy kunit tests still pass after this change.

2023-04-04powerpc/isa-bridge: Remove open coded "ranges" parsingRob Herring
"ranges" is a standard property with common parsing functions. Users shouldn't be implementing their own parsing of it. Reimplement the ISA brige "ranges" parsing using the common ranges iterator functions. The common routines are flexible enough to work on PCI and non-PCI to ISA bridges, so refactor pci_process_ISA_OF_ranges() and isa_bridge_init_non_pci() into a single implementation.

2023-04-04powerpc/papr_scm: Update the NUMA distance table for the target nodeAneesh Kumar K.V
Platform device helper routines won't update the NUMA distance table while creating a platform device, even if the device is present on a NUMA node that doesn't have memory or CPU. This is especially true for pmem devices. If the target node of the pmem device is not online, we find the nearest online node to the device and associate the pmem device with that online node. To find the nearest online node, we should have the numa distance table updated correctly. Update the distance information during the device probe. For a papr scm device on NUMA node 3 distance_lookup_table value for distance_ref_points_depth = 2 before and after fix is below: Before fix: node 3 distance depth 0 - 0 node 3 distance depth 1 - 0 node 4 distance depth 0 - 4 node 4 distance depth 1 - 2 node 5 distance depth 0 - 5 node 5 distance depth 1 - 1 After fix node 3 distance depth 0 - 3 node 3 distance depth 1 - 1 node 4 distance depth 0 - 4 node 4 distance depth 1 - 2 node 5 distance depth 0 - 5 node 5 distance depth 1 - 1 Without the fix, the nearest numa node to the pmem device (NUMA node 3) will be picked as 4. After the fix, we get the correct numa node which is 5.

Specify the bus-type property for all three connected MAX96712. The default behavior when parsing a node without this property is to default to D-PHY. Making this explicit plays it safe and future proofs things as the default parsing comes from the V4L2 core and not the driver itself.

2023-04-04um: Only disable SSE on clang to work around old GCC bugsDavid Gow
As part of the Rust support for UML, we disable SSE (and similar flags) to match the normal x86 builds. This both makes sense (we ideally want a similar configuration to x86), and works around a crash bug with SSE generation under Rust with LLVM. However, this breaks compiling stdlib.h under gcc < 11, as the x86_64 ABI requires floating-point return values be stored in an SSE register. gcc 11 fixes this by only doing register allocation when a function is actually used, and since we never use atof(), it shouldn't be a problem: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99652 Nevertheless, only disable SSE on clang setups, as that's a simple way of working around everyone's bugs.
