These were noticed when building sandbox on a Raspberry Pi 400, which uses
32-bit linux.
To make this work, I enabled CONFIG_HOST_32BIT in 'make menuconfig'. It
would be nice if that were automatic, since we have the logic already in
arch/sandbox/config.mk
So this series adds that.
It also fixes the unicode warnings of the form:
/usr/bin/ld: warning: arch/sandbox/cpu/start.o uses 2-byte wchar_t yet the
output is to use 4-byte wchar_t; use of wchar_t values across objects
may fail
as suggested by Heinrich.
Changes in v5:
- Resync with upstream instead
Changes in v4:
- Rebase to master
- Use $(HOSTCC) instead of gcc
- Add proper Kconfig help
Changes in v3:
- Change some things EFI things missed (or new since) last time
- Use 'bitness' instead of 'bit'
- Add a new patch to change non-EFI occurences
Changes in v2:
- Drop patches previously applied
- Put all the packages in gcc.rst

This resyncs us with the version found in v5.16 of the Linux kernel with
the following exceptions:
- Keep our u-boot specific tests / code area.
- Change the location of checkpatch.rst
- Drop the "use strscpy" test as we don't have that, but do have strlcpy
and want that used now.
- Keep debug/printf in the list for $logFunctions
This also syncs the spdxcheck.py tool and all the associated
documentation.

+ Use of __constant_<foo> form is discouraged for the following functions::
+
+ __constant_cpu_to_be[x]
+ __constant_cpu_to_le[x]
+ __constant_be[x]_to_cpu
+ __constant_le[x]_to_cpu
+ __constant_htons

+
+ Using any of these outside of include/uapi/ is not preferred as using the
+ function without __constant_ is identical when the argument is a
+ constant.
+
+ In big endian systems, the macros like __constant_cpu_to_be32(x) and
+ cpu_to_be32(x) expand to the same expression::
+
+ #define __constant_cpu_to_be32(x) ((__force __be32)(__u32)(x))

+
+ In little endian systems, the macros __constant_cpu_to_be32(x) and

+ has a __builtin_constant_p check::
+
+ #define __swab32(x) \
+ (__builtin_constant_p((__u32)(x)) ? \
+ ___constant_swab32(x) : \
+ __fswab32(x))
+
+ So ultimately they have a special case for constants.
+ Similar is the case with all of the macros in the list. Thus
+ using the __constant_... forms are unnecessarily verbose and
+ not preferred outside of include/uapi.
+
+ See: https://lore.kernel.org/lkml/1400106425.12666.6.camel@joe-AO725/

+
+ **DEVICE_ATTR_FUNCTIONS**
+ The function names used in DEVICE_ATTR is unusual.
+ Typically, the store and show functions are used with <attr>_store and
+ <attr>_show, where <attr> is a named attribute variable of the device.
+
+ Consider the following examples::
+
+ static DEVICE_ATTR(type, 0444, type_show, NULL);
+ static DEVICE_ATTR(power, 0644, power_show, power_store);
+
+ The function names should preferably follow the above pattern.
+
+ See: https://www.kernel.org/doc/html/latest/driver-api/driver-model/device.html#attributes
+
+ **DEVICE_ATTR_RO**
+ The DEVICE_ATTR_RO(name) helper macro can be used instead of
+ DEVICE_ATTR(name, 0444, name_show, NULL);
+
+ Note that the macro automatically appends _show to the named
+ attribute variable of the device for the show method.
+
+ See: https://www.kernel.org/doc/html/latest/driver-api/driver-model/device.html#attributes
+
+ **DEVICE_ATTR_RW**
+ The DEVICE_ATTR_RW(name) helper macro can be used instead of
+ DEVICE_ATTR(name, 0644, name_show, name_store);
+
+ Note that the macro automatically appends _show and _store to the
+ named attribute variable of the device for the show and store methods.

+ See: https://www.kernel.org/doc/html/latest/driver-api/driver-model/device.html#attributes

+ named attribute variable of the device for the store method.

+ Commit d91bff3011cf ("proc/sysctl: add shared variables for range
+ check") added some shared const variables to be used instead of a local
+ copy in each source file.
+
+ Consider replacing the sysctl range checking value with the shared
+ one in include/linux/sysctl.h. The following conversion scheme may
+ be used::

+ &one -> SYSCTL_ONE
+ &int_max -> SYSCTL_INT_MAX

+ **IN_ATOMIC**
+ in_atomic() is not for driver use so any such use is reported as an ERROR.

+
+ **MULTILINE_DEREFERENCE**
+ A single dereferencing identifier spanned on multiple lines like::
+
+ struct_identifier->member[index].
+ member = <foo>;
+
+ is generally hard to follow. It can easily lead to typos and so makes
+ the code vulnerable to bugs.
+
+ If fixing the multiple line dereferencing leads to an 80 column
+ violation, then either rewrite the code in a more simple way or if the
+ starting part of the dereferencing identifier is the same and used at
+ multiple places then store it in a temporary variable, and use that
+ temporary variable only at all the places. For example, if there are
+ two dereferencing identifiers::
+
+ member1->member2->member3.foo1;
+ member1->member2->member3.foo2;
+
+ then store the member1->member2->member3 part in a temporary variable.
+ It not only helps to avoid the 80 column violation but also reduces
+ the program size by removing the unnecessary dereferences.
+
+ But if none of the above methods work then ignore the 80 column
+ violation because it is much easier to read a dereferencing identifier
+ on a single line.
+
+ **TRAILING_STATEMENTS**
+ Trailing statements (for example after any conditional) should be
+ on the next line.
+ Statements, such as::
+
+ if (x == y) break;

+ should be::

+ **SINGLE_STATEMENT_DO_WHILE_MACRO**
+ For the multi-statement macros, it is necessary to use the do-while
+ loop to avoid unpredictable code paths. The do-while loop helps to
+ group the multiple statements into a single one so that a

+
+ But for the single statement macros, it is unnecessary to use the
+ do-while loop. Although the code is syntactically correct but using
+ the do-while loop is redundant. So remove the do-while loop for single
+ statement macros.

At present if you build sandbox on a 32-bit host a lot of errors are
produced. This is because CONFIG_HOST_64BIT is enabled by default.
It is quite annoying to have to change that manually before building
sandbox. It is also quite confusing for new users.
Add a way to detect the setting and add the appropriate
CONFIG_HOST_64BIT=y or CONFIG_HOST_32BIT=y to the defconfig, to avoid
this issue.
Tidy up the Kconfig help for the above two options while we are here.

Changes in v4:
- Use $(HOSTCC) instead of gcc
- Add proper Kconfig help
Changes in v3:
- Use 'bitness' instead of 'bit'
Changes in v2:
- Drop patches previously applied
- Put all the packages in gcc.rst

At present we use wide characters for unicode but this is not necessary.
Change the code to use the 'u' literal instead. This helps to fix build
warnings for sandbox on rpi.
Note: This applies tree-wide

This pretty reliably fails to build for me with
CONFIG_HOST_DETECT_BITNESS=y resulting in CONFIG_SANDBOX_BITS_PER_LONG
not being set. It's as easy to trigger as "make O=/tmp/fail
sandbox_config all" for me (over on bill-the-cat if it works for you
locally).

This does not compile on Alpine Linux:

This text is really confusing me.
Does HOST_32BIT relate to the bitness of HOSTCC that we use to compile
tools? I would not know why I should have to set HOSTCC manually.
The bitness of the binary that we build is orthogonal to the bitness of
the system that we are building on.
You can build a 64bit ARM binary on a 32bit machine and vice versa.
An i386 binary can be run on a x86_64 host. Same with ARMv7 on an ARMv8
host.
Normally I would call the machine I am building on host. But that does
not imply the bitness of the target machine nor does it imply the
bitness of the binary.
What does your usage of HOST relate to?
Best regards

Why do we need this in the commit message? You patch changes lib/ and
