Linux 4.5-rc1

Linux 4.5-rc1

[Linus Torvalds]

So the merge window is over, and rc1 is out there.  Go test!

It's a fairly normal release - neither unusually big or unusually
small. The statistics look fairly normal too, with drivers being a bit
over 70% of the bulk (the big driver areas being gpu, networking,
sound, staging, fbdev, but its all over). The shortlog is too big and
unwieldly to post, but I'm appending my "mergelog" which credits the
maintainers I merge from - not necessarily the people who did the
actual individual patches.

Aside from drivers, we have architecture updates (over half of it
being arm - both 32- and 64-bit this time around, the rest is powerpc,
x86, mips, s390). On the arch front, it's probably worth mentioning
that apparently the arm people have finalized their platform work, and
that you really can build a generic ARM kernel for all the ARMv6/7
platforms (and describe the hardware with devicetree). It's been many
years in coming. Good job.

There's also obviously the usual documentation, filesystem, generic
networking, and core kernel updates. A number of nice MM cleanuips
came in through Andrew this time around, for example, and Al Viro made
pathname lookup stay in RCU mode even over symlink traveral.

So there's a little something for anybody.

Here are some early test results:

Build results:
	total: 146 pass: 142 fail: 4
Failed builds:
	alpha:allmodconfig
	m68k:allmodconfig
	parisc:allmodconfig
	xtensa:allmodconfig

Qemu test results:
	total: 96 pass: 94 fail: 2
Failed tests:
	arm64:smp:defconfig
	arm64:nosmp:defconfig

The allmodconfig builds fail due to a problem in drm/vc4 [1]. This problem
affects all builds which have drm/vc4 enabled and pm disabled. The arm64
qemu tests fail due to access to a register which is unimplemented in qemu
for arm64 [2]. Details are available at [3].

And for me powerpc allmodconfig with:
sound/core/compress_offload.c: In function 'snd_compr_ioctl':
sound/core/compress_offload.c:804:2: error: case label does not reduce to an integer constant
  case _IOC_NR(SNDRV_COMPRESS_GET_CODEC_CAPS):
	    ^
Stephen also complained about this.
http://www.gossamer-threads.com/lists/linux/kernel/2345968

I think this is outside my boundary for any attempt to fix. Maybe with
some suggestion/guidance I can try. 

Apart from powerpc:allmodconfig:
m32r:allmodconfig
tilegx:allmodconfig
tilepro:allmodconfig

These three are for the same problem as in drm/vc4 which you mentioned.

powerpc:allmodconfig passes for me. Did you enable some additional build options ?
If not, what is your toolchain version ?

Given the discussion around it, I would not want to touch it myself.

Does any of those tend to fail differently than other allmodconfig builds ?
I am hesitant to add more builds to my tests - my build system is already
on its knees.

No extra options. Only allmodconfig.

5.3.0

No, its that same problem. Hopefully that patch will get into rc2.

I assume that means gcc.

Did you build the toolchain yourself, or did you get it from somewhere ?

Built it. Started building my own when I was having internal compiler
error with an old version of cris compiler, and there was no support as
it was very old. And when i tried to search for a new version, i could
not find any.

This 5.3.0 powerpc compiler you can find at:
http://chat.vectorindia.net/crosstool/x86_64/5.3.0/powerpc64-linux.tar.xz
