10a9794d8f MAINTAINERS: target/mips: Add MIPS files under default-configs directory
Add following files as maintained within the main MIPS target
section in MAINTAINERS:

default-configs/mips64el-linux-user.mak
default-configs/mips64-linux-user.mak
default-configs/mipsn32el-linux-user.mak
default-configs/mipsn32-linux-user.mak

default-configs/mips64-softmmu.mak
default-configs/mipsel-softmmu.mak
default-configs/mips-softmmu.mak
default-configs/mips-softmmu-common.mak

Future nanoMIPS user mode will also have its .mak file, and
because of that "*mips*" was used instead of "mips*" as a
shorthand in the new item in MAINTAINERS.

20d6c7312f RISC-V Changes for 3.2, Part 1
This pull request contains the first set of RISC-V patches I'd like to
 target for the 3.2 development cycle.  It's really just a collection of
 bug fixes with one major new feature: PCIe can now be attached to RISC-V
 guests.
 
 This has passed my usual test of booting the latest Linux RC into a
 Fedora disk image on the virt machine.

4250da1092 tcg: Improve call argument loading
Free the argument register only after we have verified that the
temporary is not already in that register.  This case is likely
now that we are back propagating the preferred register.

ae36a246ed tcg: Add TCG_OPF_BB_EXIT
Use this to notice the opcodes that exit the TB, which implies
that local temps are really dead and need not be synced.

Previously we so marked the true end of the TB, but that was
immediately overwritten by the la_bb_end invoked by any
TCG_OPF_BB_END opcode, like exit_tb.

No need for a "tcg_" prefix for a static function; we already

d62816f2db tcg: Improve register allocation for matching constraints
Try harder to honor the output_pref.  When we're forced to allocate
a second register for the input, it does not need to use the input
constraint; that will be honored by the register we allocate for the
output and a move is already required.

b016486e7b tcg: Add preferred_reg argument to tcg_reg_alloc
This new argument will aid register allocation by indicating how
the temporary will be used in future.  If the preference cannot
be satisfied, fall back to the constraints of the current insn.

Short circuit the preference when it cannot be satisfied or if
it does not further constrain the operation.

With an eye toward optimizing function call sequences, optimize
for the preferred_reg set containing a single register.

For the moment, all users pass 0 for preference.

f1e2e38ee0 pvrdma: check return value from pvrdma_idx_ring_has_ routines
pvrdma_idx_ring_has_[data/space] routines also return invalid
index PVRDMA_INVALID_IDX[=-1], if ring has no data/space. Check
return value from these routines to avoid plausible infinite loops.

509f57c98e pvrdma: release ring object in case of an error
create_cq and create_qp routines allocate ring object, but it's
not released in case of an error, leading to memory leakage.
