The write_raw_cp_reg's value argument should be a uint64_t, since that's what all its callers hand it and what all the functions it calls take.

The read_raw_cp_reg and write_raw_cp_reg functions can now never fail (in fact they should never have failed previously unless there was a bug in a reginfo that meant no raw accessor was provided for a might-trap register). This allows us to clean up their prototypes so the write function returns void and the read function returns the value read, which in turn lets us simplify the callers.

All cpreg read and write functions now return 0, so we can clean up their prototypes: * write functions return void * read functions return the value rather than taking a pointer to write the value to This is a fairly mechanical change which makes only the bare minimum set of changes to the callers of read and write functions.

Several of the system registers handled via the ARMCPRegInfo mechanism have access trap control bits controlling whether the registers are accessible to lower privilege levels. Replace the existing mechanism (allowing the read and write functions to return EXCP_UDEF if access is denied) with a dedicated "check access rights" function pointer in the ARMCPRegInfo. This will allow us to simplify some of the register definitions, which no longer need read/write functions purely to handle the access checks. We take the opportunity to define the return value from the access checking function in a way that allows us to set the correct exception syndrome information for exceptions taken to AArch64 (which may need to distinguish access failures due to a configurable trap or enable from other kinds of access failure). This commit defines the new mechanism but does not move any of the registers across to use it.

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.

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).
