Mention the maximum voltages of the CEC and HPD lines. Since in the example these lines are connected to a Raspberry Pi and the Rpi GPIO lines are 3.3V it is a good idea to warn against directly connecting the HPD to the Raspberry Pi's GPIO line.

2018-01-23perf trace: Remove audit-libs dependency if syscall tables are presentHendrik Brueckner
Change the Makefile and build process to no longer require audit-libs interfaces when the architecture provides system call tables. Committer notes: Its not enough to hook into the NO_LIBAUDIT makefile block, we need to define a CONFIG_TRACE that gets selected by both architectures generating the syscall tables from the kernel headers and from detecting the availability of libaudit. With that in place we will not link against libaudit even if the necessary files are available for that, in fact we will not even try to detect its availability, speeding up a bit the feature detection phase.

2018-01-23perf trace: Obtain errno strings by using arch_syscalls__strerrno()Hendrik Brueckner
Replace the errno_to_name() from the audit-libs with the newly introduced arch_syscalls__strerrno() function. With this change: 1. With replacing errno_to_name() from audit-libs, perf trace does no longer require audit-lib interfaces. 2. In addition to 1, the audit-libs dependency can be removed for architectures that support syscall tables in perf. This is achieved in a follow-up commit. 3. With the architecture specific errno number/name mapping, perf trace reports can work across architectures.

2018-01-23perf util: Introduce architecture specific errno/name mappingHendrik Brueckner
Introduce a script that generates a mapping of errno numbers to their names for each architecture that is supported by perf (i.e. has a subdirectory in tools/perf/arch/). The errno mapping is generated as part of the trace beautifiers and can be used by including the trace/beauty/arch_errno_names.c file. Then, use arch_syscalls__strerrno() to look up an errno value to obtain the errno name (e.g. ENOENT) for a particular architecture.

2018-01-23perf symbols: Using O_CLOEXEC in do_openWang YanQing
I've meet a strange behavior with these commands on my gentoo box: 1: perf kmem record 2: CTRL-C to stop 1 3: perf report 4: "Enter", "Enter", "Run scripts for all samples", "event_analyzing_sample". Then 'perf report' says: " No kallsyms or vmlinux with build-id xxxx was found /lib/modules/4.10.0+/build/vmlinux with build id xxxx not found, continuing without symbols ". It is strange because I am sure /lib/modules/4.10.0+/build/vmlinux is right for perf.data. After digging, I found out the reason is that "perf report" generates many open fds, then "script_browse" uses popen to run "perf script" which run out of open files. The gentoo box has a small default value for "max open files", 1024. Yes, "ulimit -n " with a bigger number could fix it, but I think that using O_CLOEXEC in do_open is a better way.

There can be a race, if receive_buf call comes before tty initialization completes in n_tty_open and tty->disc_data may be NULL.

2018-01-23s390/decompressor: discard __ksymtab and .eh_frame sectionsVasily Gorbik
__ksymtab sections created for exported symbols are not needed during the decompressor phase and could be discarded to save the memory. The source of those exports is ebcdic.o, which is linked into both vmlinux and boot/compressed/vmlinux. .eh_frame section is also unused and could be discarded from boot/compressed/vmlinux. The same has been done for vmlinux in: "s390/kernel: emit CFI data in .debug_frame and discard .eh_frame sections".

2018-01-23s390: fix handling of -1 in set{,fs}[gu]id16 syscallsEugene Syromiatnikov
For some reason, the implementation of some 16-bit ID system calls (namely, setuid16/setgid16 and setfsuid16/setfsgid16) used type cast instead of low2highgid/low2highuid macros for converting [GU]IDs, which led to incorrect handling of value of -1 (which ought to be considered invalid). Discovered by strace test suite.

2018-01-23s390/tools: generate header files in arch/s390/include/generated/Hendrik Brueckner
Previously, the generated dis.h and facilities.h header files have been stored in include/generated. Because they are s390 specific, store them in the arch/s390/include/generated/asm/ directory. Also update references to the header files respectively. To prevent name collisions with those header files in asm/ that include the generated ones, rename the generated headers files and add an -defs suffix. Also update the generators to create the ifdef guards respectively.
