The ARM946 has 8 PRBS (protection region base and size) registers. Currently we implement these with a CP_ANY reginfo; however this underdecodes (since there are 16 possible values of CRm but only 8 registers) and we catch the invalid values in the read and write functions. However this causes issues with migration since we only migrate the first of a wildcard register set, so we only migrate c6_region[0]. It also makes it awkward to pull reginfo access checks out into their own function. Avoid all these problems by just defining separate reginfo structs for each of the 8 registers; this also lets us avoid having any read or write functions and will result in more efficient direct field accesses from generated code.

Log guest attempts to access unimplemented system registers via the LOG_UNIMP reporting mechanism (for both the 32 bit and 64 bit instruction sets). This is particularly useful for debugging problems where the guest is trying to use a system register that QEMU doesn't implement.

This resolves the build issue with building the ROMs on OpenBSD on x86 archs. As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the whole OS/packages and so forth. The ROMs need to have PIE disabled. Check in configure whether the compiler supports the flags for disabling PIE, and if it does then use them for building the ROMs. This fixes the following buildbot failure: >From the OpenBSD buildbots..

by default, patterns/names in .gitignore are applied recursively to all subdirectories. So any name mentioned in .gitignore is ignored in all subdirectores. This is good for, say. object files (*.o), but not good for particular names which should be ignored only in one directory. For example, qemu-img.1 file is generated in the top directory, and it should be ignored only there, not in some subdir. At first, this might not matter much, but we have lots of examples already where it actually does not help at all. For example, top-level .gitignore ignores a file/dir named "patches" (which is very questionable by itself), but it is applied recursively, so git also ignores, for example, debian/patches/ which should not be ignored. So anchor all the names where appropriate. .gitignore should be cleaned up further, which will be addressed in a subsequent patch. Signed-off-by: NMichael Tokarev <mjt@tls.msk.ru>

Over time, lots of stuff moved from vl.c into separate files. But include statements has never been cleaned, and they continue to carry lots of anymore-unused stuff. Remove includes which are not relevant for vl.c anymore. Apparently there are more includes like this, because many are included from qemu-common.h and the like, or, for example, I don't see were we use win32-specific stuff in vl.c (so that maybe #include <windows.h> might be removed too).

When starting a block job, commit_active_start() relies on whether *errp is set by mirror_start_job. This allows it to determine if the mirror job start failed, so that it can clean up any changes to open flags from the bdrv_reopen(). If errp is NULL, then it will not be able to determine if mirror_start_job failed or not. To avoid this, use a local Error variable, and then propagate the error (if any) to errp.

iSCSI currently does not need to do any actions to support the current usage of bdrv_reopen(). However, it is important to note a couple of things: 1.) A connection will not be re-established to an iSCSI target, and 2.) If iscsi_open() is changed to parse 'flags', then iscsi_reopen_prepare() may need to be more than a stub.
