Systems affected by Neoverse-N1 #1542419 support DIC so do not need to perform icache maintenance once new instructions are cleaned to the PoU. For the errata workaround, the kernel hides DIC from user-space, so that the unnecessary cache maintenance can be trapped by firmware. To reduce the number of traps, produce a fake IminLine value based on PAGE_SIZE.

2019-10-25arm64: psci: Reduce the waiting time for cpu_psci_cpu_kill()Yunfeng Ye1-6/+9
In cases like suspend-to-disk and suspend-to-ram, a large number of CPU cores need to be shut down. At present, the CPU hotplug operation is serialised, and the CPU cores can only be shut down one by one. In this process, if PSCI affinity_info() does not return LEVEL_OFF quickly, cpu_psci_cpu_kill() needs to wait for 10ms. If hundreds of CPU cores need to be shut down, it will take a long time. Normally, there is no need to wait 10ms in cpu_psci_cpu_kill(). So change the wait interval from 10 ms to max 1 ms and use usleep_range() instead of msleep() for more accurate timer. In addition, reducing the time interval will increase the messages output, so remove the "Retry ..." message, instead, track time and output to the the sucessful message.

Convert the glue code for the PowerPC SPE implementations of AES-ECB, AES-CBC, AES-CTR, and AES-XTS from the deprecated "blkcipher" API to the "skcipher" API. This is needed in order for the blkcipher API to be removed. Tested with: export ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- make mpc85xx_defconfig cat >> .config << EOF # CONFIG_MODULES is not set # CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set CONFIG_DEBUG_KERNEL=y CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y CONFIG_CRYPTO_AES=y CONFIG_CRYPTO_CBC=y CONFIG_CRYPTO_CTR=y CONFIG_CRYPTO_ECB=y CONFIG_CRYPTO_XTS=y CONFIG_CRYPTO_AES_PPC_SPE=y EOF make olddefconfig make -j32 qemu-system-ppc -M mpc8544ds -cpu e500 -nographic \ -kernel arch/powerpc/boot/zImage \ -append cryptomgr.fuzz_iterations=1000 Note that xts-ppc-spe still fails the comparison tests due to the lack of ciphertext stealing support. This is not addressed by this patch. This patch also cleans up the code by making ->encrypt() and ->decrypt() call a common function for each of ECB, CBC, and XTS, and by using a clearer way to compute the length to process at each step.

2019-10-25powerpc/powernv/eeh: Fix oops when probing cxl devicesFrederic Barrat1-1/+1
Recent cleanup in the way EEH support is added to a device causes a kernel oops when the cxl driver probes a device and creates virtual devices discovered on the FPGA: BUG: Kernel NULL pointer dereference at 0x000000a0 Faulting instruction address: 0xc000000000048070 Oops: Kernel access of bad area, sig: 7 [#1] ... NIP eeh_add_device_late.part.9+0x50/0x1e0 LR eeh_add_device_late.part.9+0x3c/0x1e0 Call Trace: _dev_info+0x5c/0x6c (unreliable) pnv_pcibios_bus_add_device+0x60/0xb0 pcibios_bus_add_device+0x40/0x60 pci_bus_add_device+0x30/0x100 pci_bus_add_devices+0x64/0xd0 cxl_pci_vphb_add+0xe0/0x130 [cxl] cxl_probe+0x504/0x5b0 [cxl] local_pci_probe+0x6c/0x110 work_for_cpu_fn+0x38/0x60 The root cause is that those cxl virtual devices don't have a representation in the device tree and therefore no associated pci_dn structure. In eeh_add_device_late(), pdn is NULL, so edev is NULL and we oops. We never had explicit support for EEH for those virtual devices. Instead, EEH events are reported to the (real) pci device and handled by the cxl driver. Which can then forward to the virtual devices and handle dependencies. The fact that we try adding EEH support for the virtual devices is new and a side-effect of the recent cleanup. This patch fixes it by skipping adding EEH support on powernv for devices which don't have a pci_dn structure. The cxl driver doesn't create virtual devices on pseries so this patch doesn't fix it there intentionally.

2019-10-25arm64: dts: ls1028a: fix a compatible issueYuantian Tang1-1/+1
The I2C multiplexer used on ls1028aqds is PCA9547, not PCA9847. If the wrong compatible was used, this chip will not be able to be probed correctly and hence fail to work.

2019-10-25x86/ftrace: Get rid of function_hookBorislav Petkov2-12/+9
History lesson courtesy of Steve: "When ftrace first was introduced to the kernel, it used gcc's mcount profiling mechanism. The mcount mechanism would add a call to "mcount" at the start of every function but after the stack frame was set up. Later, in gcc 4.6, gcc introduced -mfentry, that would create a call to "__fentry__" instead of "mcount", before the stack frame was set up. In order to handle both cases, ftrace defined a macro "function_hook" that would be either "mcount" or "__fentry__" depending on which one was being used. The Linux kernel no longer supports the "mcount" method, thus there's no reason to keep the "function_hook" define around. Simply use "__fentry__", as there is no ambiguity to the name anymore." Drop it everywhere. Signed-off-by: Borislav Petkov <bp@suse.de> Acked-by: Jiri Slaby <jslaby@suse.cz> Cc: "H.

2019-10-25ARM: dts: Disable DMA support on the BK4 vf610 device's fsl_lpuartLukasz Majewski1-0/+4
This change disables the DMA support (RX/TX) on the NXP's fsl_lpuart driver - the PIO mode is used instead. This change is necessary for better robustness of BK4's device use cases with many potentially interrupted short serial transfers. Without it the driver hangs when some distortion happens on UART lines.
