LPAE extends the DBGDRAR and DBGDSAR debug registers to 64 bits; we only implement these as dummy RAZ versions; provide dummies for the 64 bit accesses as well. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Add implementations of the AMAIR0 and AMAIR1 LPAE Auxiliary Memory Attribute Indirection Registers. These are implementation defined and we choose to implement them as RAZ/WI, matching the Cortex-A7 and Cortex-A15. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Implement the privileged-execute-never (PXN) translation table bit. It is implementation-defined whether this is implemented, so we give it its own ARM_FEATURE_ flag. LPAE requires PXN, so add also an LPAE feature flag and the implication logic, as a placeholder for actually implementing LPAE at a later date.

Make target_phys_addr_t 64 bits for ARM targets, and set TARGET_PHYS_ADDR_SPACE_BITS to 40. This should have no effect for ARM boards where physical addresses really are 32 bits (except perhaps a slight performance hit on 32 bit hosts for system emulation) but allows us to implement the Large Physical Address Extensions for Cortex-A15, which mean 40 bit physical addresses.

Fix errors in the TCG temp handling in the 64 bit coprocessor write path: we were reusing a 32 bit temp after it had been freed by store_reg(), and failing to free a 64 bit temp. This bug has no visible effect at this point because there aren't any non-NOP 64 bit registers yet; it needs to be fixed as a prerequisite for the 64 bit registers in LPAE support.

Fix a couple of cases where cp register names were copy-and-pasted. These are harmless since we don't use the name for anything (except debugging convenience) but could be confusing. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Reviewed-by: NIgor Mitsyanko <i.mitsyanko@samsung.com>

The coprocessor register rework broke cp15 based WFI instructions. We incorrectly fall through the normal register write case, which incorrectly adds a forced block termination. We've already done a special version of this (DISAS_WFI), so return immediately.

The Buildbot has detected a new failure on builder default_i386_rhel61 while building qemu. Full details are available at: http://buildbot.b1-systems.de/qemu/builders/default_i386_rhel61/builds/304 The proper fix is non-trivial so let's disable the build by default until it's fixed properly.

Users may pass the following parameters to qemu: $ qemu-kvm -net nic -net user,smb= ... $ qemu-kvm -net nic -net user,smb ... $ qemu-kvm -net nic -net user,smb=bad_directory ... In these cases, qemu started successfully while samba server failed to start. Users will confuse since samba server failed silently without any indication of what it did wrong. To avoid it, we check whether the shared directory exist and if users have permission to access this directory when QEMU's "built-in" SMB server is enabled.

When using guestfwd=, Qemu only connects the virtual server's TCP port to a single chardev. This is useless in most cases, as we usually want to have more than a single connection from the guest to the outside world. This patch adds a new cmd: target to guestfwd= that allows for execution of a command on every TCP connection. This leverages the same code as the -smb parameter, just that here the command is user defined.

bdrv_get_floppy_geometry_hint() fails to store through its parameter drive when bs has a geometry hint. Makes fd_revalidate() assign random crap to drv->drive. Has been broken that way for ages. Harmless, because: * The only way to set a geometry hint is -drive if=none,cyls=... Since commit c219331e, probably unintentional. * The only use of drv->drive is as argument to another bdrv_get_floppy_geometry_hint(). Which doesn't use it, since the geometry hint is still there. Drop the broken code, ignore -drive parameter cyls, heads and secs for floppies even with if=none, just like before commit c219331e. Matches -help, which explains cyls, heads, secs as "hard disk physical geometry". Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

The new function can be made a bit nicer than bdrv_append. It swaps the whole contents, and then swaps back (using the usual t=a;a=b;b=t idiom) the fields that need to stay on top.
