[ Upstream commit d1befa65823e9c6d013883b8a41d081ec338c489 ] vdso_fault used is_compat_task function (on s390 it tests "current" thread_info flags) to distinguish compat tasks and map 31-bit vdso pages. But "current" task might not correspond to mm context. When 31-bit compat inferior is executed under gdb, gdb does PTRACE_PEEKTEXT on vdso page, causing vdso_fault with "current" being 64-bit gdb process. So, 31-bit inferior ends up with 64-bit vdso mapped. To avoid this problem a new compat_mm flag has been introduced into mm context. This flag is used in vdso_fault and vdso_mremap instead of is_compat_task.

[ Upstream commit 85a88cabad57d26d826dd94ea34d3a785824d802 ] When performing partition migrations all present CPUs must be online as all present CPUs must make the H_JOIN call as part of the migration process. Once all present CPUs make the H_JOIN call, one CPU is returned to make the rtas call to perform the migration to the destination system. During testing of migration and changing the SMT state we have found instances where CPUs are offlined, as part of the SMT state change, before they make the H_JOIN call. This results in a hung system where every CPU is either in H_JOIN or offline. To prevent this this patch disables CPU hotplug during the migration process.

[ Upstream commit 063b8b1251fd069f3740339fca56119d218f11ba ] The updates to powerpc numa and memory hotplug code now use the in-kernel LMB array instead of the device tree. This change allows the pseries memory DLPAR code to only update the device tree once after successfully handling a DLPAR request. Prior to the in-kernel LMB array, the numa code looked up the affinity for memory being added in the device tree, the code now looks this up in the LMB array. This change means the memory hotplug code can just update the affinity for an LMB in the LMB array instead of updating the device tree. This also provides a savings in kernel memory. When updating the device tree old properties are never free'ed since there is no usecount on properties. This behavior leads to a new copy of the property being allocated every time a LMB is added or removed (i.e. a request to add 100 LMBs creates 100 new copies of the property). With this update only a single new property is created when a DLPAR request completes successfully.

[ Upstream commit 56d20861c027498b5a1112b4f9f05b56d906fdda ] Call Frame Information is used by gdb for back-traces and inserting breakpoints on function return for the "finish" command. This failed when inside __kernel_clock_gettime. More concerning than difficulty debugging is that CFI is also used by stack frame unwinding code to implement exceptions. If you have an app that needs to handle asynchronous exceptions for some reason, and you are unlucky enough to get one inside the VDSO time functions, your app will crash. What's wrong: There is control flow in __kernel_clock_gettime that reaches label 99 without saving lr in r12. CFI info however is interpreted by the unwinder without reference to control flow: It's a simple matter of "Execute all the CFI opcodes up to the current address". That means the unwinder thinks r12 contains the return address at label 99. Disabuse it of that notion by resetting CFI for the return address at label 99. Note that the ".cfi_restore lr" could have gone anywhere from the "mtlr r12" a few instructions earlier to the instruction at label 99. I put the CFI as late as possible, because in general that's best practice (and if possible grouped with other CFI in order to reduce the number of CFI opcodes executed when unwinding). Using r12 as the return address is perfectly fine after the "mtlr r12" since r12 on that code path still contains the return address. __get_datapage also has a CFI error. That function temporarily saves lr in r0, and reflects that fact with ".cfi_register lr,r0". A later use of r0 means the CFI at that point isn't correct, as r0 no longer contains the return address. Fix that too.

[ Upstream commit bd73a3dd257fb838bd456a18eeee0ef0224b7a40 ] while compiling an ipq4019 target, dtc will complain: regulator@b089000 unit address format error, expected "2089000" The saw0 regulator reg value seems to be copied and pasted from qcom-ipq8064.dtsi. This patch fixes the reg value to match that of the unit address which in turn silences the warning. (There is no driver for qcom,saw2 right now.

[ Upstream commit 4a63c1ffd384ebdce40aac9c997dab68379137be ] For userspace to tell the difference between an random signal and an exception, the exception must include siginfo information. Using SEND_SIG_FORCED for SIGSEGV is thus wrong, and it will result in userspace seeing si_code == SI_USER (like a random signal) instead of si_code == SI_KERNEL or a more specific si_code as all exceptions deliver. Therefore replace force_sig_info(SIGSEGV, SEND_SIG_FORCE, current) with force_sig(SIG_SEGV, current) which gets this right and is shorter and easier to type.
