Strange thing is that this file does not look to have changed.
Maybe it's a result of enabling the new config option CRYPTO_DEV_MV_CESA?

Seems unrelated. Kernel compiles fine with CRYPTO_DEV_MV_CESA set and
CRYPTO_CAST6 unset. I did have CRYPTO_CAST6 set to m for .31 kernel
builds without seeing any problems.
As I'm running Debian stable there've no major changes (if any) in the
build environment.

* [PATCH] arm: new W macro to WORD_ACCESS

Cc: linux-kernel, linux-crypto, Herbert Xu, Catalin Marinas,
linux-arm-kernel
As reported by Frans Pop the new global macro W on ARM which is included
via
|arch/arm/include/asm/uaccess.h:20
|include/linux/uaccess.h:5
|include/linux/crypto.h:26
|crypto/cast6.c:23
leads to a build error because the crypto/cast6.c defines a function
which is named W.

please don't blame my shiny new driver :)
Catalin: bisect leads to 8b592783a. I've renamed the macro in this
commit and everything else I found due to compile error. Hope the new
name is acceptable. I think W in global name space is a bad thing to do.
In crypto there are many one letter identifier.
Since you use this in assembly code only you might want to move it to
another header file which does get included from every .c file.

* [PATCH] arm: new W macro to WORD_ACCESS
@ 2009-09-16 17:58 ` Sebastian Andrzej Siewior

From: Sebastian Andrzej Siewior @ 2009-09-16 17:58 UTC (permalink / raw)
To: linux-arm-kernel
As reported by Frans Pop the new global macro W on ARM which is included
via
|arch/arm/include/asm/uaccess.h:20
|include/linux/uaccess.h:5
|include/linux/crypto.h:26
|crypto/cast6.c:23
leads to a build error because the crypto/cast6.c defines a function
which is named W.

>Maybe it's a result of enabling the new config option CRYPTO_DEV_MV_CESA?
please don't blame my shiny new driver :)
Catalin: bisect leads to 8b592783a. I've renamed the macro in this
commit and everything else I found due to compile error. Hope the new
name is acceptable. I think W in global name space is a bad thing to do.
In crypto there are many one letter identifier.
Since you use this in assembly code only you might want to move it to
another header file which does get included from every .c file.

W has nothing to do with the access size, so this change makes it _really_
confusing. What it's about is telling the compiler to use the ARM 32-bit
version of the instruction coding when building for Thumb2 (which
can intermix Thumb and ARM instruction sets.)
So the macro needs to be renamed... NAK on this patch as it stands.

This was already reported by Alexey Dobriyan and I included his patch in
my Thumb-2 branch (and -next for now):
http://linux-arm.org/git?p=linux-2.6.git;a=commitdiff;h=4fb3c2e2ab3549308a1b1663296d165e45d72ba5
Since this macro is only used in ARM assembly code, the patch simply
adds some ifdefs around it.
Russell, if you are OK with Alexey's patch, I'll send you a pull request
(though for only one patch, alternatively just merge it manually).
