Ulrich Spörlein b93ce255b5 Document the detrimental effect of kern.cam.XX.retry_count for recoverdisk(1)
recoverdisk(1) wants to know about read errors when doing the 1MB/64k
reads as fast as possible so it can continue and retry them later with
smaller reads (down to sector size). Any retries by lower layers will
only slow it down.

Ulrich Spörlein cabdddae57 Pull up vendor changes to mdoc(7)
This switches us to using -isoC-2011 as the symbol name which is used by
groff and mdocml. It follows the change to 4 digit years as done with
IEEE Std 1003 post-1999.

John Baldwin a2cb1d522b Add new variants of the IF_ADDR_*LOCK*() macros used for protecting
interface address lists that distinguish read locks from write locks.
To preserve the KPI, the previous operations are mapped to the write
lock macros.  The lock is still kept as a mutex for now.

Robert Watson 19d52de5f4 When extracting the VLAN tag from if_em and if_lem receive descriptor
rings, copy the whole VLAN tag, not just the VLAN ID.  This fixes a
problem in which VLAN priority information was dropped when using

Ed Schouten cede7d22fe Remove _Complex_I workaround from <tgmath.h>.
This removes the use of __typeof() from this header, thus making it work
with a plain C11 compiler.
2012-01-05 12:06:49 +00:00
Ed Schouten f92d9d7d37 Make _Complex_I a proper float _Complex when using GCC 4.2.
It turns out our GCC has quite an interesting bug:

	typeof(1.0fi) != float _Complex
	typeof((float _Complex)1.0fi) != float _Complex
	typeof((float _Complex)1.0i) == float _Complex

In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.

To prevent foot-shooting, add a _Static_assert() to guarantee that
_Complex_I is always a float _Complex. I'm not going to MFC this part of
the diff.

Ed Schouten 069a43171f Reimplement <tgmath.h> on top of __generic().
The macro construction used now, is almost identical to the code
provided in C11 proposal N1404. This new version doesn't seem to
introduce any regressions according to the regression test in tools/,
but still seems to malfunction with Clang on certain aspects.

The new code does work successfully with GCC 4.2, 4.6 and 4.7. With 4.7,
it also works when __generic() is implemented on top of _Generic().

Ed Schouten f8fd121ca4 Add __generic(), to be able to use a very simple _Generic().
Already introducing this allows us to be forward compatible with C11
compilers. By implementing <tgmath.h> on top of this interface, it
becomes trivial to support both our existing GCC and newer compilers.

all pages are cleared after the vm_object_page_clean() returned.
