2012-12-19target-alpha: Avoid leaking the alarm timer over resetAndreas Färber
Move the timer from CPUAlphaState to AlphaCPU to avoid the pointer being zero'ed once we implement reset. Would cause a segfault in sys_helper.c:helper_set_alarm(). This also simplifies timer initialization in Typhoon. Signed-off-by: Andreas Färber <afaerber@suse.de> Acked-by: Richard Henderson <rth@twiddle.net>

this declaration is wrong: the correct prototype on linux is: int setgroups(size_t size, const gid_t *list); since by default musl libc exposes this symbol in unistd.h additionally to grp.h, the wrong declaration causes a build error. the proper fix is to simply include the correct header.

remove_port() is called from qdev's unplug callback, and we're certain the port will be found in our list of ports. Adding an assert() documents this.

Stuff the cpkt before calling send_control_msg(). This function should not be concerned about contents of the buffer it receives. A few code refactorings recently have made making this change easier than earlier. Coverity and clang have flagged this code several times in the past (cpkt->id not set before send_control_event() passed it on to send_control_msg()). This will finally eliminate the false-positive.

2012-12-15target-xtensa: fix ITLB/DTLB page protection flagsMax Filippov
With MMU option xtensa architecture has two TLBs: ITLB and DTLB. ITLB is only used for code access, DTLB is only for data. However TLB entries in both TLBs have attribute field controlling write and exec access. These bits need to be properly masked off depending on TLB type before being used as tlb_set_page prot argument. Otherwise the following happens: (1) ITLB entry for some PFN gets invalidated (2) DTLB entry for the same PFN gets updated, attributes allow code execution (3) code at the page with that PFN is executed (possible due to step 2), entry for the TB is written into the jump cache (4) QEMU TLB entry for the PFN gets replaced with an entry for some other PFN (5) code in the TB from step 3 is executed (possible due to jump cache) and it accesses data, for which there's no DTLB entry, causing DTLB miss exception (6) re-translation of the TB from step 5 is attempted, but there's no QEMU TLB entry nor xtensa ITLB entry for that PFN, which causes ITLB miss exception at the TB start address (7) ITLB miss exception is handled by the guest, but execution is resumed from the beginning of the faulting TB (the point where ITLB miss occured), not from the point where DTLB miss occured, which is wrong. With that fix the above scenario causes ITLB miss exception (that used to be step 7) at step 3, right at the beginning of the TB.

2012-12-14pseries: Increase default NVRAM sizeDavid Gibson
If no image file for NVRAM is specified, the pseries machine currently creates a 16K non-persistent NVRAM by default. This basically works, but is not large enough for current firmware and guest kernels to create all the NVRAM partitions they would like to. Increasing the default size to 64K addresses this and stops the guest generating error messages.

2012-12-14target-ppc: Don't use hwaddr to represent hardware stateDavid Gibson
The hwaddr type is somewhat vaguely defined as being able to contain bus addresses on the widest possible bus in the system. For that reason it's discouraged for representing specific pieces of persistent hardware state, which should instead use an explicit width type that matches the bits available in real hardware. In particular, because of the possibility that the size of hwaddr might change if different buses are added to the target in future, it's not suitable for use in vm state descriptions for savevm and migration. This patch purges such unwise uses of hwaddr from the ppc target code, which turns out to be just one. The ppcemb_tlb_t struct, used on a number of embedded ppc models to represent a TLB entry contains a hwaddr for the real address field. This patch changes it to be a fixed uint64_t which is suitable enough for all machine types which use this structure. Other uses of hwaddr in CPUPPCState turn out not to be problematic: htab_base and htab_mask are just used for the convenience of the TCG code; the underlying machine state is the SDR1 register, which is stored with a suitable type already. Likewise the mpic_cpu_base field is only used internally and does not represent fundamental hardware state which needs to be saved.

2012-12-14PPC: E500plat: Make a lot of PCI slots availableAlexander Graf
