[Qemu-devel] [PATCH v2 0/3] TLS abstraction layer for thread-local cpu_single_env on Linux

[Peter Maydell <peter.maydell@linaro.org>]

These patches add enough of the TLS abstraction layer to allow us
to make cpu_single_env thread-local on Linux systems. This fixes
the regression described in bug 823902 for the 1.0 release; we
can add the Win32 and POSIX implementations later.

I haven't included Paolo's "Prepare Windows port for thread-local
cpu_single_env" patch -- it would be safe to do so but it isn't
necessary until we actually implement TLS for Win32.

Changes v1->v2:
 * fix Paolo's email address
 * split the darwin-user change out into a separate patch
 * drop the 'tls_' prefix from the cpu_single_env tls var name

  darwin-user/main.c: Drop unused cpu_single_env definition
  Make cpu_single_env thread-local
