Targeting old glibc
Hi,
I wonder what is the right way to target an old glibc?
I have a machine which is up to date (glibc 2.32 and clang+lld 10.0.1).
So far I've been able to target older glibc by having a C file containing:
__asm__(".symver powf,powf at GLIBC_2.2.5");
__asm__(".symver expf,expf at GLIBC_2.2.5");
__asm__(".symver exp2f,exp2f at GLIBC_2.2.5");

[PATCH 1/3] Paravirtualization: Kernel Ring Cleanups
Hi all,
I've been looking at finding common ground between the VMI, Xen and
other paravirtualization approaches, and after some discussion, we're
getting somewhere.
These first two patches are the fundamentals, stolen mainly from the
VMI patches: removing assumptions about the kernel running in ring 0,
and macro-izing all the obvious para-virtualize-needing insns. The
third patch is
