| * arm64: bpf: make BPF prologue and epilogue align with ARM64 AAPCSYang Shi2015-11-171-5/+39

However, ARM64 JIT used FP (x29) as eBPF fp register, FP is subjected to change during function call so it may cause the BPF prog stack base address change too. Use x25 to replace FP as BPF stack base register (fp). Since x25 is callee saved register, so it will keep intact during function call. It is initialized in BPF prog prologue when BPF prog is started to run everytime. Save and restore x25/x26 in BPF prologue and epilogue to keep them intact for the outside of BPF. Actually, x26 is unnecessary, but SP requires 16 bytes alignment. So, the BPF stack layout looks like: high original A64_SP => 0:+-----+ BPF prologue |FP/LR| current A64_FP => -16:+-----+ | ... | callee saved registers +-----+ | | x25/x26 BPF fp register => -80:+-----+ | | | ... | BPF prog stack | | | | current A64_SP => +-----+ | | | ... | Function call stack | | +-----+ low CC: Zi Shen Lim <zlim.lnx@gmail.com> CC: Xi Wang <xi.wang@gmail.com> Signed-off-by: Yang Shi <yang.shi@linaro.org> Acked-by: Zi Shen Lim <zlim.lnx@gmail.com> Signed-off-by: David S.

| * bpf, arm64: start flushing icache range from headerDaniel Borkmann2015-11-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While recently going over ARM64's BPF code, I noticed that the icache range we're flushing should start at header already and not at ctx.image. Reason is that after b569c1c622c5 ("net: bpf: arm64: address randomize and write protect JIT code"), we also want to make sure to flush the random-sized trap in front of the start of the actual program (analogous to x86).

We don't trust any and all bootloaders because some will fiddle with CPU configuration so we go ahead and massage each CPU into sanity again. For example, some dell BIOSes have this XD disable feature which set IA32_MISC_ENABLE[34] and disable NX. This might be some dumb workaround for other OSes but Linux sure doesn't need it. A similar thing is present in the Surface 3 firmware - see https://bugzilla.kernel.org/show_bug.cgi?id=106051 - which sets this bit only on the BSP: # rdmsr -a 0x1a0 400850089 850089 850089 850089 I know, right?! There's not even an off switch in there. So fix all those cases by sanitizing the 64-bit entry point too. For that, make verify_cpu() callable in 64-bit mode also. Requested-and-debugged-by: "H.

These instances don't have i8259 legacy PIC but they use legacy IRQs for serial port, rtc, and acpi. With this commit included we end up with these IRQs not initialized. Earlier, there was a special workaround for legacy IRQs in mp_map_pin_to_irq() doing mp_irqdomain_map() without looking at nr_legacy_irqs() and now we fail in __irq_domain_alloc_irqs() when irq_domain_alloc_descs() returns -EEXIST. The essence of the issue seems to be that early_irq_init() calls arch_probe_nr_irqs() to figure out the number of legacy IRQs before we probe for i8259 and gets 16. Later when init_8259A() is called we switch to NULL legacy PIC and nr_legacy_irqs() starts to return 0 but we already have 16 descs allocated. Solve the issue by separating i8259 probe from init and calling it in arch_probe_nr_irqs() before we actually use nr_legacy_irqs() information.

No instructions are executed until an interrupt occurs. The processor's clocks are stopped if both threads are in idle mode. Description: Execution of this instruction puts the thread into wait state, an idle mode in which no instructions are fetched or executed. The thread remains in wait state until an interrupt occurs that is not masked by the interrupt mask field in the Status register. Then, if interrupts are enabled by the IE bit in the Status register, the interrupt is serviced. The ERET instruction returns to the instruction following the WAIT instruction. If interrupts are disabled, the processor resumes executing instructions with the next sequential instruction. Programming notes: The WAIT instruction should be executed while interrupts are disabled by the IE bit in the Status register. This avoids a potential timing hazard, which occurs if an interrupt is taken between testing the counter and executing the WAIT instruction. In this hazard case, the interrupt will have been completed before the WAIT instruction is executed, so the processor will remain indefinitely in wait state until the next interrupt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting pm_power_off is apprently wrong and makes drivers such as gpio-poweroff not work.

| * | | | MIPS: ralink: Remove check for CONFIG_PCI on non-PCI SoCsJohn Crispin2015-11-111-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code currently panics if PCI is enabled but the SoC has no PCI bus. This check is superfluous as the driver only loads if enabled in the devicetree.

| * | | | MIPS: ralink: Add tty detectionJohn Crispin2015-11-111-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MT7688 has several uarts that can be used for console. There are several boards in the wild, that use ttyS1 or ttyS2. This patch applies a simply autodetection routine to figure out which ttyS the bootloader used as console. The uarts come up in 6 bit mode by default. The bootloader will have set 8 bit mode on the console. Find that 8bit tty and use it.

Increase the idle speed of the core to fix this if the kernel is built with USB support. The "magic" values are taken from the Ralink SDK Kernel.
