The tls.h inclusion is not really required and limits possible
definition on more arch specific headers.
This is a cleanup to allow inline functions on sysdep.h, more
specifically on i386 and ia64 which requires to access some tls
definitions its own.
No semantic changes expected, checked with a build against all
affected ABIs.
Commit 24731685 ("prlimit: Translate old_rlimit from RLIM64_INFINITY to
RLIM_INFINITY") broken the getrlimit64 for 32-bit configurations which
do no need the 2GiB limited compat getrlimit (default version >= 2.2).
This patch fixes that by restoring the weak alias in that case.
Changelog:
* sysdeps/unix/sysv/linux/getrlimit64 (getrlimit64)
[!__RLIM_T_MATCHES_RLIM64_T]
[!SHLIB_COMPAT (libc, GLIBC_2_1, GLIBC_2_2)]: Define as weak alias of
__getrlimit64. Add libc_hidden_weak.
Fix the RLIM_INFINITY and RLIM64_INFINITY constants on alpha to match
the kernel one and all other architectures. Change the getrlimit,
getrlimit64, setrlimit, setrlimit64 into old compat symbols, and provide
the Linux generic functions as GLIBC_2_27 version.
Changelog:
* sysdeps/unix/sysv/linux/getrlimit64.c [USE_VERSIONED_RLIMIT]: Do not
define getrlimit and getrlimit64 as weak aliases of __getrlimit64.
Define __GI_getrlimit64 as weak alias of __getrlimit64.

instead.

__getrlimit64 function and provide it as getrlimit@@GLIBC_2_27 and
getrlimit64@@GLIBC_2_27.
* sysdeps/unix/sysv/linux/alpha/setrlimit64.c: Ditto with setrlimit
and setrlimit64.

Changelog:
* sysdeps/unix/sysv/linux/alpha/getrlimit64.c (__old_getrlimit64):
Drop __RLIM_T_MATCHES_RLIM64_T conditional as __old_getrlimit64 is
never defined in that case.

[BZ #18822]
* sysdeps/unix/sysv/linux/getrlimit64.c (__new_getrlimit): Add
attribute_hidden.
This patch makes sysdeps/unix/sysv/linux code assume the prlimit64
syscall is always available, given the minimum of a 3.2 kernel.
__ASSUME_PRLIMIT64, which in fact was no longer used, is removed.
Code conditional on __NR_prlimit64 being defined is made
unconditional. Fallback code for the case where prlimit64 produces an
ENOSYS error is removed, substantially simplifying some functions.
Tested for x86_64 and x86.
* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_PRLIMIT64):
Remove macro.
* sysdeps/unix/sysv/linux/getrlimit64.c (__getrlimit64): Assume
prlimit64 is always available and does not give an ENOSYS error.
* sysdeps/unix/sysv/linux/prlimit.c [__NR_prlimit64]: Make code
unconditional.
[!__NR_prlimit64]: Remove conditional code.
* sysdeps/unix/sysv/linux/setrlimit.c (__setrlimit): Assume
prlimit64 is always available and does not give an ENOSYS error.
* sysdeps/unix/sysv/linux/setrlimit64.c (__setrlimit64): Likewise.
This patch consolidates all Linux setrlimit and getrlimit on the default
sysdeps/unix/sysv/linux/{set,get}rlimit{64}.c. It contains two exceptions:
1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19
and higher due a broken RLIM64_INFINITY constant.
2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB
limit. I am not sure if it is required, but a RLIM_INFINITY fix [1]
change its definition without adding a compat symbol. This patch does
not aim to address this possible issue, it follow current symbol
export.
The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64)
and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This
code path is only used on kernel older than 2.6.36 (basically now only x86)
and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once
x86 moves to be on par with other architectures regarding minimum kernel
supported we can get rid of using old syscalls and default path.
A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as
default for 64 bits ports. This allows the default implementation to avoid
{get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit.
Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a
sanity build plus check-abi on all other supported architectures.

posix_spawn (a standard POSIX function) brings in a use of getrlimit64
(not a standard POSIX function). This patch fixes this by using
__getrlimit64 and making getrlimit64 a weak alias.
This is more complicated than some such changes because of files that
define getrlimit64 in their own way using symbol versioning after
including the main sysdeps/unix/sysv/linux/getrlimit64.c with a
getrlimit macro defined. There are various existing patterns for such
cases in glibc; the one I've used here is that a getrlimit64 macro
disables the weak_alias / libc_hidden_weak calls, leaving it to the
including file to define the getrlimit64 name in whatever way is
appropriate.
Tested for x86_64 and x86 that installed stripped shared libraries are
unchanged by this patch.
