2019-10-28clk: imx7ulp: do not export out IMX7ULP_CLK_MIPI_PLL clockFancy Fang1-1/+0
The mipi pll clock comes from the MIPI PHY PLL output, so it should not be a fixed clock. MIPI PHY PLL is in the MIPI DSI space, and it is used as the bit clock for transferring the pixel data out and its output clock is configured according to the display mode. So it should be used only for MIPI DSI and not be exported out for other usages. Signed-off-by: Fancy Fang <chen.fang@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2019-10-28x86/cpu: Add a "tsx=" cmdline option with TSX disabled by defaultPawan Gupta1-0/+26
Add a kernel cmdline parameter "tsx" to control the Transactional Synchronization Extensions (TSX) feature. On CPUs that support TSX control, use "tsx=on|off" to enable or disable TSX. Not specifying this option is equivalent to "tsx=off". This is because on certain processors TSX may be used as a part of a speculative side channel attack. Carve out the TSX controlling functionality into a separate compilation unit because TSX is a CPU feature while the TSX async abort control machinery will go to cpu/bugs.c.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-10-27 The following pull-request contains BPF updates for your *net-next* tree. We've added 52 non-merge commits during the last 11 day(s) which contain a total of 65 files changed, 2604 insertions(+), 1100 deletions(-). The main changes are: 1) Revolutionize BPF tracing by using in-kernel BTF to type check BPF assembly code. The work here teaches BPF verifier to recognize kfree_skb()'s first argument as 'struct sk_buff *' in tracepoints such that verifier allows direct use of bpf_skb_event_output() helper used in tc BPF et al (w/o probing memory access) that dumps skb data into perf ring buffer. Also add direct loads to probe memory in order to speed up/replace bpf_probe_read() calls, from Alexei Starovoitov. 2) Big batch of changes to improve libbpf and BPF kselftests. Besides others: generalization of libbpf's CO-RE relocation support to now also include field existence relocations, revamp the BPF kselftest Makefile to add test runner concept allowing to exercise various ways to build BPF programs, and teach bpf_object__open() and friends to automatically derive BPF program type/expected attach type from section names to ease their use, from Andrii Nakryiko. 3) Fix deadlock in stackmap's build-id lookup on rq_lock(), from Song Liu. 4) Allow to read BTF as raw data from bpftool. Most notable use case is to dump /sys/kernel/btf/vmlinux through this, from Jiri Olsa. 5) Use bpf_redirect_map() helper in libbpf's AF_XDP helper prog which manages to improve "rx_drop" performance by ~4%., from Björn Töpel. 6) Fix to restore the flow dissector after reattach BPF test and also fix error handling in bpf_helper_defs.h generation, from Jakub Sitnicki. 7) Improve verifier's BTF ctx access for use outside of raw_tp, from Martin KaFai Lau. 8) Improve documentation for AF_XDP with new sections and to reflect latest features, from Magnus Karlsson. 9) Add back 'version' section parsing to libbpf for old kernels, from John Fastabend. 10) Fix strncat bounds error in libbpf's libbpf_prog_type_by_name(), from KP Singh. 11) Turn on -mattr=+alu32 in LLVM by default for BPF kselftests in order to improve insn coverage for built BPF progs, from Yonghong Song. 12) Misc minor cleanups and fixes, from various others. ==================== Signed-off-by: David S.

2019-10-25PCI/DPC: Add "pcie_ports=dpc-native" to allow DPC without AER controlOlof Johansson1-0/+2
Prior to eed85ff4c0da7 ("PCI/DPC: Enable DPC only if AER is available"), Linux handled DPC events regardless of whether firmware had granted it ownership of AER or DPC, e.g., via _OSC. PCIe r5.0, sec 6.2.10, recommends that the OS link control of DPC to control of AER, so after eed85ff4c0da7, Linux handles DPC events only if it has control of AER. On platforms that do not grant OS control of AER via _OSC, Linux DPC handling worked before eed85ff4c0da7 but not after. To make Linux DPC handling work on those platforms the same way they did before, add a "pcie_ports=dpc-native" kernel parameter that makes Linux handle DPC events regardless of whether it has control of AER.

2019-10-25x86/ftrace: Get rid of function_hookBorislav Petkov1-2/+2
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."
