2015-06-15arm: Implement uniprocessor with MP configPeter Crosthwaite2-2/+7
Add a boolean for indicating uniprocessors with MP extensions. This drives the U bit in MPIDR. Prepares support for Cortex-R5.

2015-06-15arm: Refactor get_phys_addr FSR return mechanismPeter Crosthwaite3-64/+78
Currently, the return code for get_phys_addr is overloaded for both success/fail and FSR value return. This doesn't handle the case where there is an error with a 0 FSR. This case exists in PMSAv7. So rework get_phys_addr and friends to return a success/failure boolean return code and populate the FSR via a caller provided uint32_t pointer.

2015-06-15target-arm: Add the THUMB_DSP featureAurelio C. Remonda3-10/+107
Create an ARM_FEATURE_THUMB_DSP controlling the Thumb encodings of the 85 DSP instructions (these are all Thumb2). This is enabled for all non-M-profile CPUs with Thumb2 support, as the instructions are mandatory for R and A profiles. On M profile they are optional and not present in the Cortex-M3 (though they are in the M4). The effect of this commit is that we will now treat the DSP encodings as illegal instructions on M3, when previously we incorrectly implemented them. Signed-off-by: Aurelio C.

2015-06-15target-arm: Handle "extended small page" descriptors correctlyPeter Maydell1-4/+9
The old ARMv5-style page table format includes a kind of second level descriptor named the "extended small page" format, whose primary purpose is to allow specification of the TEX memory attribute bits on a 4K page. This exists on ARMv6 and also (as an implementation extension) on XScale CPUs; it's UNPREDICTABLE on v5. We were mishandling this in two ways: (1) we weren't implementing it for v6 (probably never noticed because Linux will use the new-style v6 page table format there) (2) we were not correctly setting the page_size, which is 4K, not 1K The latter bug went unnoticed for years because the only thing which the page_size affects is which TLB entries get flushed when the guest does a TLB invalidate on an address in the page, and prior to commit 2f0d8631b7 we were doing a full TLB flush very frequently due to Linux's habit of writing the SCTLR pointlessly a lot. (We can assume that after commit 2f0d8631b7 the bug went unnoticed for a year because nobody's actually using the Zaurus/XScale emulation...) Report the correct page size for these descriptors, and permit them on ARMv6 CPUs. This fixes a problem where a kernel image for Zaurus can boot the kernel OK but gets random segfaults when it tries to run userspace programs.

Starting with version 4.9, GCC assumes it can't safely dereference null pointers, and uses this for some optimizations. On s390, the lowcore memory is located at address 0, so this assumption is wrong and breaks the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.

When reopening an image, the block layer already takes care to reopen bs->file as well with recalculated inherited flags. The same must happen for any other child (most notably missing before this patch: backing files). If bs->file (or any other child) didn't originally inherit from bs, e.g. because it was created separately and then only referenced, it must not inherit flags on reopen either, so check the inherited_from field before propagation the reopen down. VMDK already reopened its extents manually; this code can now be dropped.

2015-06-12block: Add BlockDriverState.inherits_fromKevin Wolf2-0/+21
Currently, the block layer assumes that any block node can have only one parent, and if it has a parent, that it inherits some options/flags from this parent. This is not true any more: With references used in block device creation, a single node can be used by multiple parents, or it can be created separately and not inherit flags from any parent. To handle reopens correctly, a node must know from which parent it inherited options. This patch adds the information to BlockDriverState.

2015-06-12block: Add list of children to BlockDriverStateKevin Wolf2-0/+45
This allows iterating over all children of a given BDS, not only including bs->file and bs->backing_hd, but also driver-specific ones like VMDK extents or Quorum children. For bdrv_swap(), the list of children of the swapped BDS stays at that BDS (because that's where the pointers stay as well). The list head moves and pointers to it must be fixed up therefore. The list of children in the parent of the swapped BDS is not affected by the swap. The contents of the BDS objects is swapped, so the existing pointer in the parent automatically points to the newly swapped in BDS.
