* ARM: 8847/1: pm: fix HYP/SVC mode mismatch when MCPM is usedMarek Szyprowski2020-01-293-1/+14
| | | | | | | | | | | | | | | | | | | | | | [ Upstream commit ca70ea43f80c98582f5ffbbd1e6f4da2742da0c4 ] MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to perform low-level platform initialization. This results in a try to install HYP stubs for the second time for each CPU and results in false HYP/SVC mode mismatch detection. The HYP stubs are already installed at the beginning of the kernel initialization on the boot CPU (head.S) or in the secondary_startup() for other CPUs. To fix this issue MCPM code should use a cpu_resume() routine without HYP stubs installation. This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid XU3/XU4/HC1 boards.

* ARM: vexpress: Set-up shared OPP table instead of individual for each CPUSudeep Holla2020-01-121-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 2a76352ad2cc6b78e58f737714879cc860903802 ] Currently we add individual copy of same OPP table for each CPU within the cluster. This is redundant and doesn't reflect the reality. We can't use core cpumask to set policy->cpus in ve_spc_cpufreq_init() anymore as it gets called via cpuhp_cpufreq_online()->cpufreq_online() ->cpufreq_driver->init() and the cpumask gets updated upon CPU hotplug operations. It also may cause issues when the vexpress_spc_cpufreq driver is built as a module. Since ve_spc_clk_init is built-in device initcall, we should be able to use the same topology_core_cpumask to set the opp sharing cpumask via dev_pm_opp_set_sharing_cpus and use the same later in the driver via dev_pm_opp_get_sharing_cpus.

* libfdt: define INT32_MAX and UINT32_MAX in libfdt_env.hMasahiro Yamada2020-01-041-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit a8de1304b7df30e3a14f2a8b9709bb4ff31a0385 ] The DTC v1.5.1 added references to (U)INT32_MAX. This is no problem for user-space programs since <stdint.h> defines (U)INT32_MAX along with (u)int32_t. For the kernel space, libfdt_env.h needs to be adjusted before we pull in the changes. In the kernel, we usually use s/u32 instead of (u)int32_t for the fixed-width types. Accordingly, we already have S/U32_MAX for their max values. So, we should not add (U)INT32_MAX to <linux/limits.h> any more. Instead, add them to the in-kernel libfdt_env.h to compile the latest libfdt.

This means that the read/write is not atomic even when performed to a 16-bit-aligned address. This leads to problems with vhost: vhost uses __getuser() to read the vring's 16-bit avail.index field, and if it happens to observe a partial update of the index, wrong descriptors will be used which will lead to a breakdown of the virtio communication. A similar problem exists for __putuser() which is used to write to the vring's used.index field. The reason these functions use strb[t]/ldrb[t] is because strht/ldrht instructions did not exist until ARMv6T2/ARMv7. So we should be easily able to fix this on ARMv7. Also, since all ARMv6 processors also don't actually use the unprivileged instructions anymore for uaccess (since CONFIG_CPU_USE_DOMAINS is not used) we can easily fix them too.

* ARM: 8802/1: Call syscall_trace_exit even when system call skippedTimothy E Baldwin2019-11-251-5/+4
| | | | | | | | | | | | | | | | | | | | | [ Upstream commit f18aef742c8fbd68e280dff0a63ba0ca6ee8ad85 ] On at least x86 and ARM64, and as documented in the ptrace man page a skipped system call will still cause a syscall exit ptrace stop. Previous to this commit 32-bit ARM did not, resulting in strace being confused when seccomp skips system calls. This change also impacts programs that use ptrace to skip system calls.

| | | | | | | | | | | | | | | | [ Upstream commit d2db7773ba864df6b4e19643dfc54838550d8049 ] So far we have only supported 3 level page table with fixed IPA of 40bits, where PUD is folded. With 4 level page tables, we need to check if the PUD entry is valid or not. Fix stage2_flush_memslot() to do this check, before walking down the table.
