8372c3a0cb MAINTAINERS: Update my email address
The old Wind River email address (bin.meng@windriver.com) is no longer
available due to an internal infrastructure change within the company.
While a new email address (bin.meng.cn@windriver.com) has been assigned
to me, I am unable to find a way to send this patch directly from the
new address. Presumably, the basic authentication with client submission
(SMTP AUTH) [1] has been disabled by the company's IT.

Switch to use my personal email address instead.

285a8f209a qapi: Simplify QAPISchemaVariants @tag_member
For union types, the tag member is known only after .check().

We used to code this in a simple way: QAPISchemaVariants attribute
.tag_member was None for union types until .check().

Since this complicated typing, recent commit "qapi/schema: fix typing
for QAPISchemaVariants.tag_member" hid it behind a property.

The previous commit lets us treat .tag_member just like the other
attributes that become known only in .check(): declare, but don't
initialize it in .__init__().

QAPISchemaAlternatives.check(), where the conditions are always

QAPISchemaBranches.  Move it there.

1d067e3953 qapi: New QAPISchemaBranches, QAPISchemaAlternatives
QAPISchemaVariants represents either a union type's branches, or an
alternate type's alternatives.  Much of its code is conditional on
which one it actually is.

Create QAPISchemaBranches for branches, and QAPISchemaAlternatives for
alternatives, both subtypes of QAPISchemaVariants.

Replace QAPISchemaVariants by one of them where possible.  Keep it
only where we actually deal with either of them.

QAPISchemaVariants.__init__() takes @tag_name and @tag_member, where
exactly one must be None: @tag_name for alternatives, @tag_member for
branches.  Let QAPISchemaBranches.__init__() take just @tag_name, and
QAPISchemaAlternatives.__init__() take just @tag_member.

A later patch will move the conditional code to the subtypes.

2f0a771ddc Hexagon (target/hexagon) Only pass env to generated helper when needed
Currently, we pass env to every generated helper.  When the semantics of
the instruction only depend on the arguments, this is unnecessary and
adds extra overhead to the helper call.

We add the TCG_CALL_NO_RWG_SE flag to any non-HVX helpers that don't get
the ptr to env.

The A2_nop and SA1_setin1 instructions end up with no arguments.  This
results in a "old-style function definition" error from the compiler, so
we write overrides for them.

With this change, the number of helpers with env argument is
    idef-parser enabled:    329 total, 23 with env
    idef-parser disabled:   1543 total, 550 with env
