The current implementation of pci_find_space does not correctly align
PCI capabilities in the PCI configuration space. It also does not
support PCI-Express devices. This patch fixes these issues.

I accidentally posted the patch, which is here, on the wrong bug report

it was committed and fixes this issue:

fixed. The other bug report I recently filed was fixed.

Title:
Thread cancell
Public bug reported:
Thread cancellation (and certain other implementation-internal things
such as set*id() and timers) are implemented in userspace on Linux by
stealing a couple of the realtime signals for internal use by the
implementation, leaving them unavailable to applications. Unfortunately
On x86_64, remove the constraint on the third argument register which
is not needed:

value should not be in the two first argument registers as they are
used in tcg_out_tlb_load().
- For stores the helper arguments are env, a
Now that CONFIG_TCG_PASS_AREG0 has been removed, it's easier to get
an optimal code for the load/store functions.

address end-up in the second register instead of the first one. Adjust

Create a safe wrapper by protecting the signal mask.
Instead of doing a simple passthrough of the sigprocmask, the wrapper

Let me resend this patch, because it looks ignored except for the comment from
Richard Henderson for which I've replied.
Here is the 6th version of the series optimizing TCG qemu_ld/st code generation.
v6:
- Remove an extra argument of return addr from MMU helpers
Instead, embed the fast
Add optimized TCG qemu_ld/st generation which locates the code of TLB miss
cases at the end of a block after generating the other IRs.
Currently, this optimization supports only i386 and x86_64 hosts.

Add GETPC_EXT which is used by MMU helpers to selectively calculate the code
