MFC r331797:

2018-04-08T16:54:07Z

Use an accessor function to access ifr_data. This fixes 32-bit compat (no ioctl command defintions are required as struct ifreq is the same size). Reviewed by: kib Obtained from: CheriBSD Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D14900

sys/dev: minor spelling fixes.

Most affect comments, very few have user-visible effects.

sys: use our roundup2/rounddown2() macros when param.h is available.

2016-04-21T19:57:40Z

rounddown2 tends to produce longer lines than the original code and when the code has a high indentation level it was not really advantageous to do the replacement. This tries to strike a balance between readability using the macros and flexibility of having the expressions, so not everything is converted.

sys/dev: use our nitems() macro when it is avaliable through param.h.

No functional change, only trivial cases are done in this sweep, Drivers that can get further enhancements will be done independently. Discussed in: freebsd-current

Fix multiple incorrect SYSCTL arguments in the kernel:

2014-10-21T07:31:21Z

- Wrong integer type was specified. - Wrong or missing "access" specifier. The "access" specifier sometimes included the SYSCTL type, which it should not, except for procedural SYSCTL nodes. - Logical OR where binary OR was expected. - Properly assert the "access" argument passed to all SYSCTL macros, using the CTASSERT macro. This applies to both static- and dynamically created SYSCTLs. - Properly assert the the data type for both static and dynamic SYSCTLs. In the case of static SYSCTLs we only assert that the data pointed to by the SYSCTL data pointer has the correct size, hence there is no easy way to assert types in the C language outside a C-function. - Rewrote some code which doesn't pass a constant "access" specifier when creating dynamic SYSCTL nodes, which is now a requirement. - Updated "EXAMPLES" section in SYSCTL manual page.

shifts into the sign bit. Instead use (1U << 31) which gets the expected result. This fix is not ideal as it assumes a 32 bit int, but does fix the issue for most cases. A similar change was made in OpenBSD. Discussed with: -arch, rdivacky Reviewed by: cperciva
