fb0b6ed0cf doc/go1.14: remove TODO about Solaris port
The solaris-amd64-oraclerel builder is passing for the main Go repo
(on tip and release branches for 1.13 and 1.12), and golang.org/x repos
(also on tip and release branches for 1.13 and 1.12).

The builder is still maintained as described at
https://golang.org/issue/15581#issuecomment-550368581.

fccf2edbe1 doc/go1.14: remove TODO about Illumos port
There is an active builder that was added in CL 201597,
and it is passing on Go tip and release-branch.go1.13
(with one failure that appears to be flaky due to being
out of memory). It's also passing on all golang.org/x repos
on tip and release-branch.go1.13. It's not configured to
run on Go 1.12 release branches.

6e592c2b6d go/types: unexport Checker.LookupFieldOrMethod
Implementation changes in go/types for #6977 required that internal
LookupFieldOrMethod calls had access to the current *Checker. In
order to make quick progress, I added a *Checker receiver to the
function LookupFieldOrMethod (thus making it a method), and added
a new function LookupFieldOrMethod. The plan was always to rename
that function (Checker.LookupFieldOrMethod) such that it wouldn't
be exported; with the obvious name being Checker.lookupFieldOrMethod.
But that name was already in use which is why I postponed the rename.
Eventually I forgot to clean it up. This CL fixes that with the
following renames:

Checker.lookupFieldOrMethod => Checker.rawLookupFieldOrMethod
Checker.LookupFieldOrMethod => Checker.lookupFieldOrMethod

Updates #6977.
Fixes #36916.

67fee6005d go/build: update TestImportDirNotExist to accept more detailed error strings
In CL 203820, we switched go/build to use the caller's working
directory for the main module (rather than srcDir), so that go/build
resolution now respects the requirements and replacements of the main
module. When the passed-in srcDir is empty, as of that CL we use "go
list" instead of falling back to in-process (GOPATH-mode) path lookup.

Unfortunately, that broke go/build.TestImportDirNotExist when
GO111MODULE=on: the test was looking for the specific error message
produced by the in-process lookup.

This change relaxes the test to accept the error message produced by
"go list" when srcDir is empty.

2e4f490b31 cmd/compile,cmd/link: fix and re-enable open-coded defers on riscv64
The R_CALLRISCV relocation marker is on the JALR instruction, however the actual
relocation is currently two instructions previous for the AUIPC+ADDI sequence.
Adjust the platform dependent offset accordingly and re-enable open-coded defers.

Fixes #36786.

c436eadbc3 net/http: don't treat an alternate protocol as a known round tripper
As of CL 175857, the client code checks for known round tripper
implementations, and uses simpler cancellation code when it finds one.
However, this code was not considering the case of a request that uses
a user-defined protocol, where the user-defined protocol was
registered with the transport to use a different round tripper.
The effect was that round trippers that worked with earlier
releases would not see the expected cancellation semantics with tip.

Fixes #36820

e7f9e17b79 runtime: ensure that searchAddr always refers to inUse memory
This change formalizes an assumption made by the page allocator, which
is that (*pageAlloc).searchAddr should never refer to memory that is not
represented by (*pageAlloc).inUse. The portion of address space covered
by (*pageAlloc).inUse reflects the parts of the summary arrays which are
guaranteed to mapped, and so looking at any summary which is not
reflected there may cause a segfault.

In fact, this can happen today. This change thus also removes a
micro-optimization which is the only case which may cause
(*pageAlloc).searchAddr to point outside of any region covered by
(*pageAlloc).inUse, and adds a test verifying that the current segfault
can no longer occur.

b13ce14c4a src/go.mod: import x/crypto/cryptobyte security fix for 32-bit archs
cryptobyte: fix panic due to malformed ASN.1 inputs on 32-bit archs

	When int is 32 bits wide (on 32-bit architectures like 386 and arm), an
	overflow could occur, causing a panic, due to malformed ASN.1 being
	passed to any of the ASN1 methods of String.

	Tested on linux/386 and darwin/amd64.

	This fixes CVE-2020-7919 and was found thanks to the Project Wycheproof
	test vectors.

x/crypto/cryptobyte is used in crypto/x509 for parsing certificates.
Malformed certificates might cause a panic during parsing on 32-bit
architectures (like arm and 386).
