From 139ace95756a61715a18051c102bd67ca5166b3c Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 8 May 2017 10:45:20 +0000 Subject: Require Linux kernel 3.2 or later on x86 / x86_64. As per the recent discussion, this patch implements a requirement for Linux 3.2 or later for x86 and x86_64. This is only the initial change to increase the configured minimum; it's expected that followup patches would deal with associated removal of conditionals that are no longer needed. If we remove the start-up test on the kernel version, of course the NEWS and README text should then be revised (to reflect that this version is just one such that glibc does not intend to include compatibility code for any older kernel version, rather than older kernels necessarily failing to work or glibc necessarily having compatibility code for newer interfaces). The followups would be able to assume presence of getcpu (x86_64), recvmmsg (not always through its own syscall, sometimes only through socketcall), sendmmsg (likewise), /proc/$pid/task/$tid/comm, f_flags from statfs, prlimit64. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/i386/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/i386/configure: Regenerated. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/x86_64/64/configure: Regenerated. * README: Update statement about Linux kernel requirements. --- README | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'README') diff --git a/README b/README index be687c7..c3d17d1 100644 --- a/README +++ b/README @@ -17,9 +17,7 @@ GNU/Hurd support requires out-of-tree patches that will eventually be incorporated into an official GNU C Library release.
