#include <sysdep.h>
#include <tls.h>
Include <kernel-features.h> explicitly where required. This patch makes files using __ASSUME_* macros include <kernel-features.h> explicitly, rather than relying on some other header (such as tls.h, lowlevellock.h or pthreadP.h) to include it implicitly. (I omitted cases where I've already posted or am testing the patch that stops the file from needing __ASSUME_* at all.) This accords with the general principle of making source files include the headers for anything they use, and also helps make it safe to remove <kernel-features.h> includes from any file that doesn't use __ASSUME_* (some of those may be stray includes left behind after increasing the minimum kernel version, others may never have been needed or may have become obsolete after some other change).

powerpc: Add hwcap/hwcap2/platform data to TCB. This patch adds a new feature for powerpc. In order to get faster access to the HWCAP/HWCAP2 bits and platform number (i.e. for implementing __builtin_cpu_is () / __builtin_cpu_supports () in GCC) without the overhead of reading from the auxiliary vector, we now reserve space for them in the TCB. This is an ABI change for GLIBC 2.23. A new versioned symbol '__parse_hwcap_and_convert_at_platform' is available to get the data from the auxiliary vector and parse it, and store it for later use in the TLS initialization code. This function is called very early (in _dl_sysdep_start () via DL_PLATFORM_INFO for the dynamic linking case, and in __libc_start_main () for the static linking case) to make sure the data is available at the time of TLS initialization. * sysdeps/powerpc/Makefile (sysdep-dl-routines): Add hwcapinfo.

powerpc: abort transaction in syscalls Linux kernel powerpc documentation states issuing a syscall inside a transaction is not recommended and may lead to undefined behavior. It also states syscalls does not abort transactoin neither they run in transactional state. To avoid side-effects being visible outside transactions, GLIBC with lock elision enabled will issue a transaction abort instruction just before all syscalls if hardware supports hardware transactions.
