[PATCH 0/7] linux v4.6 update

[PATCH 0/7] linux v4.6 update

[Szabolcs Nagy]

i didnt deal with the x86_64 sigcontext change
(__pad0 is now ss) but i'm not sure if need to
do anything about that.

there are new libc-compat header hacks, i will
try to look for a solution that works for musl.

Szabolcs Nagy (7):
  add preadv2 and pwritev2 syscall numbers for linux v4.6
  add SO_CNX_ADVICE to sys/socket.h, new in linux v4.6
  add ETH_P_MACSEC netinet/if_ether.h, new in linux v4.6
  update siginfo struct for linux v4.6
  add CLONE_NEWCGROUP clone flag, new in linux v4.6
  add new tcp_info fields from linux v4.6
  update sys/socket.h to linux v4.6

[PATCH 1/7] add preadv2 and pwritev2 syscall numbers for linux v4.6

[Szabolcs Nagy]

the syscalls take an additional flag argument, they were added in commit
f17d8b35452cab31a70d224964cd583fb2845449 and a RWF_HIPRI priority hint
flag was added to linux/fs.h in 97be7ebe53915af504fb491fb99f064c7cf3cb09.

the syscall is not allocated for microblaze and sh yet.

[PATCH 7/7] update sys/socket.h to linux v4.6

[Szabolcs Nagy]

kernel connection multiplexor macros AF_KCM, PF_KCM, SOL_KCM were
added in linux commit ab7ac4eb9832e32a09f4e8042705484d2fb0aad3

MSG_BATCH sendmsg flag for performance optimization was added
in linux commit f092276d85b82504e8a07498f4e9e0c51f06745c

SOL_* macros are now synced with linux socket.h which is not a uapi
header and glibc did not have the macros either, but that has changed
