Yufen Wang	13198d8023	ARM: 8808/1: kexec:offline panic_smp_self_stop CPU ... [ Upstream commit 82c08c3e7f ] In case panic() and panic() called at the same time on different CPUS. For example: CPU 0: panic() __crash_kexec machine_crash_shutdown crash_smp_send_stop machine_kexec BUG_ON(num_online_cpus() > 1); CPU 1: panic() local_irq_disable panic_smp_self_stop If CPU 1 calls panic_smp_self_stop() before crash_smp_send_stop(), kdump fails. CPU1 can't receive the ipi irq, CPU1 will be always online. To fix this problem, this patch split out the panic_smp_self_stop() and add set_cpu_online(smp_processor_id(), false).

Russell King	d609e4aa50	ARM: oabi-compat: copy semops using __copy_from_user() ... Commit 8c8484a1c1 upstream. __get_user_error() is used as a fast accessor to make copying structure members as efficient as possible. However, with software PAN and the recent Spectre variant 1, the efficiency is reduced as these are no longer fast accessors. In the case of software PAN, it has to switch the domain register around each access, and with Spectre variant 1, it would have to repeat the access_ok() check for each access. Rather than using __get_user_error() to copy each semops element member, copy each semops element in full using __copy_from_user().

Russell King	9c91b96879	ARM: vfp: use __copy_from_user() when restoring VFP state ... Commit 42019fc50d upstream. __get_user_error() is used as a fast accessor to make copying structure members in the signal handling path as efficient as possible. However, with software PAN and the recent Spectre variant 1, the efficiency is reduced as these are no longer fast accessors. In the case of software PAN, it has to switch the domain register around each access, and with Spectre variant 1, it would have to repeat the access_ok() check for each access. Use __copy_from_user() rather than __get_user_err() for individual members when restoring VFP state.

Russell King	50f032cc50	ARM: signal: copy registers using __copy_from_user() ... Commit c32cd419d6 upstream. __get_user_error() is used as a fast accessor to make copying structure members in the signal handling path as efficient as possible. However, with software PAN and the recent Spectre variant 1, the efficiency is reduced as these are no longer fast accessors. In the case of software PAN, it has to switch the domain register around each access, and with Spectre variant 1, it would have to repeat the access_ok() check for each access. It becomes much more efficient to use __copy_from_user() instead, so let's use this for the ARM integer registers.

Russell King	901e325f77	ARM: bugs: add support for per-processor bug checking ... Commit 9d3a04925d upstream. Add support for per-processor bug checking - each processor function descriptor gains a function pointer for this check, which must not be an __init function. If non-NULL, this will be called whenever a CPU enters the kernel via which ever path (boot CPU, secondary CPU startup, CPU resuming, etc.) This allows processor specific bug checks to validate that workaround bits are properly enabled by firmware via all entry paths to the kernel.

Jinbum Park	1475b5ab37	ARM: 8748/1: mm: Define vdso_start, vdso_end as array ... [ Upstream commit 73b9160d0d ] Define vdso_start, vdso_end as array to avoid compile-time analysis error for the case of built with CONFIG_FORTIFY_SOURCE. and, since vdso_start, vdso_end are used in vdso.c only, move extern-declaration from vdso.h to vdso.c. If kernel is built with CONFIG_FORTIFY_SOURCE, compile-time error happens at this code. - if (memcmp(&vdso_start, "177ELF", 4)) The size of "&vdso_start" is recognized as 1 byte, but n is 4, So that compile-time error is reported.

Abel Vesa	84c9248a24	ARM: 8668/1: ftrace: Fix dynamic ftrace with DEBUG_RODATA and !FRAME_POINTER ... [ Upstream commit 6f05d0761a ] The support for dynamic ftrace with CONFIG_DEBUG_RODATA involves overriding the weak arch_ftrace_update_code() with a variant which makes the kernel text writable around the patching. This override was however added under the CONFIG_OLD_MCOUNT ifdef, and CONFIG_OLD_MCOUNT is only enabled if frame pointers are enabled. This leads to non-functional dynamic ftrace (ftrace triggers a WARN_ON()) when CONFIG_DEBUG_RODATA is enabled and CONFIG_FRAME_POINTER is not. Move the override out of that ifdef and into the CONFIG_DYNAMIC_FTRACE ifdef where it belongs.

Russell King	5bcb9c842a	ARM: avoid faulting on qemu ... commit 3aaf33bebd upstream. When qemu starts a kernel in a bare environment, the default SCR has the AW and FW bits clear, which means that the kernel can't modify the PSR A or PSR F bits, and means that FIQs and imprecise aborts are always masked. When running uboot under qemu, the AW and FW SCR bits are set, and the kernel functions normally - and this is how real hardware behaves. Fix this for qemu by ignoring the FIQ bit.

Russell King	6192f870ab	ARM: BUG if jumping to usermode address in kernel mode ... commit 8bafae202c upstream. Detect if we are returning to usermode via the normal kernel exit paths but the saved PSR value indicates that we are in kernel mode. This could occur due to corrupted stack state, which has been observed with "ftracetest". This ensures that we catch the problem case before we get to user code.

Mark Rutland	1541afbfb4	ARM: 8720/1: ensure dump_instr() checks addr_limit ... commit b9dd05c700 upstream. When CONFIG_DEBUG_USER is enabled, it's possible for a user to deliberately trigger dump_instr() with a chosen kernel address. Let's avoid problems resulting from this by using get_user() rather than __get_user(), ensuring that we don't erroneously access kernel memory. So that we can use the same code to dump user instructions and kernel instructions, the common dumping code is factored out to __dump_instr(), with the fs manipulated appropriately in dump_instr() around calls to this.

Laura Abbott	eefa5e13df	ARM: 8637/1: Adjust memory boundaries after reservations ... commit 985626564e upstream. adjust_lowmem_bounds is responsible for setting up the boundary for lowmem/highmem. This needs to be setup before memblock reservations can occur. At the time memblock reservations can occur, memory can also be removed from the system. The lowmem/highmem boundary and end of memory may be affected by this but it is currently not recalculated. On some systems this may be harmless, on others this may result in incorrect ranges being passed to the main memory allocator. Correct this by recalculating the lowmem/highmem boundary after all reservations have been made.

Ard Biesheuvel	3304f5a1cb	ARM: 8662/1: module: split core and init PLT sections ... commit b7ede5a1f5 upstream. Since commit 35fa91eed8 ("ARM: kernel: merge core and init PLTs"), the ARM module PLT code allocates all PLT entries in a single core section, since the overhead of having a separate init PLT section is not justified by the small number of PLT entries usually required for init code. However, the core and init module regions are allocated independently, and there is a corner case where the core region may be allocated from the VMALLOC region if the dedicated module region is exhausted, but the init region, being much smaller, can still be allocated from the module region. This puts the PLT entries out of reach of the relocated branch instructions, defeating the whole purpose of PLTs. So split the core and init PLT regions, and name the latter ".init.plt" so it gets allocated along with (and sufficiently close to) the .init sections that it serves. Also, given that init PLT entries may need to be emitted for branches that target the core module, modify the logic that disregards defined symbols to only disregard symbols that are defined in the same section.

Dietmar Eggemann	61100bdefb	ANDROID: arm: topology: Define TC2 energy and provide it to the scheduler ... This patch is only here to be able to test provisioning of energy related data from an arch topology shim layer to the scheduler. Since there is no code today which deals with extracting energy related data from the dtb or acpi, and process it in the topology shim layer, the content of the sched_group_energy structures as well as the idle_state and capacity_state arrays are hard-coded here. This patch defines the sched_group_energy structure as well as the idle_state and capacity_state array for the cluster (relates to sched groups (sgs) in DIE sched domain level) and for the core (relates to sgs in MC sd level) for a Cortex A7 as well as for a Cortex A15. It further provides related implementations of the sched_domain_energy_f functions (cpu_cluster_energy() and cpu_core_energy()). To be able to propagate this information from the topology shim layer to the scheduler, the elements of the arm_topology[] table have been provisioned with the appropriate sched_domain_energy_f functions.

Dietmar Eggemann	568913e203	ANDROID: arm: Enable max freq invariant scheduler load-tracking and capacity support ... Maximum Frequency Invariance has to be part of Cpu Invariance because Frequency Invariance deals only with differences in load-tracking introduces by Dynamic Frequency Scaling and not with limiting the possible range of cpu frequency. By placing Maximum Frequency Invariance into Cpu Invariance, load-tracking is scaled via arch_scale_cpu_capacity() in __update_load_avg() and cpu capacity is scaled via arch_scale_cpu_capacity() in update_cpu_capacity(). To be able to save the extra multiplication in the scheduler hotpath (__update_load_avg()) we could: 1 Inform cpufreq about base cpu capacity at boot and let it handle scale_cpu_capacity() as well. 2 Use the cpufreq policy callback which would update a per-cpu current cpu_scale and this value would be return in scale_cpu_capacity(). 3 Use per-cpu current max_freq_scale and current cpu_scale with the current patch.

The cpu capacity value depends on the micro-architecture and the maximum frequency of the cpu.

I just want to repost this to get the discussion restarted, as I still have to apply this patch with every kernel iteration to get my PB11MPCore Realview running. Testing by Neil Armstrong on the Oxnas NAS has revealed that this bug exist also on that widely deployed hardware, so we are probably currently regressing all ARM11MPCore systems.

Mark Rutland	df35a8f51f	ARM: 8634/1: hw_breakpoint: blacklist Scorpion CPUs ... commit ddc37832a1 upstream. On APQ8060, the kernel crashes in arch_hw_breakpoint_init, taking an undefined instruction trap within write_wb_reg. This is because Scorpion CPUs erroneously appear to set DBGPRSR.SPD when WFI is issued, even if the core is not powered down. When DBGPRSR.SPD is set, breakpoint and watchpoint registers are treated as undefined. It's possible to trigger similar crashes later on from userspace, by requesting the kernel to install a breakpoint or watchpoint, as we can go idle at any point between the reset of the debug registers and their later use. This has always been the case. Given that this has always been broken, no-one has complained until now, and there is no clear workaround, disable hardware breakpoints and watchpoints on Scorpion to avoid these issues.
