[PATCH] sys_kexec_load() naming fixups

2006-04-11T13:18:42+00:00

__NR_sys_kexec_load should be __NR_kexec_load.  Mainly affects users of the
_syscallN() macros, and glibc is already checking for __NR_kexec_load.

[PATCH] unify PFN_* macros

2006-03-27T16:44:48+00:00

Just about every architecture defines some macros to do operations on pfns.
 They're all virtually identical.  This patch consolidates all of them.

One minor glitch is that at least i386 uses them in a very skeletal header
file.  To keep away from #include dependency hell, I stuck the new
definitions in a new, isolated header.

Of all of the implementations, sh64 is the only one that varied by a bit.
It used some masks to ensure that any sign-extension got ripped away before
the arithmetic is done.  This has been posted to that sh64 maintainers and
the development list.

Compiles on x86, x86_64, ia64 and ppc64.

[PATCH] bitops: use non atomic operations for minix__bit() and ext2__bit()

2006-03-26T16:57:10+00:00

Bitmap functions for the minix filesystem and the ext2 filesystem except
ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic
guarantees.

But these are defined by using atomic bit operations on several architectures.
 (cris, frv, h8300, ia64, m32r, m68k, m68knommu, mips, s390, sh, sh64, sparc,
sparc64, v850, and xtensa)

This patch switches to non atomic bit operation.

[PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notifications

2006-03-25T16:22:56+00:00

Implement the half-closed devices notifiation, by adding a new POLLRDHUP
(and its alias EPOLLRDHUP) bit to the existing poll/select sets.  Since the
existing POLLHUP handling, that does not report correctly half-closed
devices, was feared to be changed, this implementation leaves the current
POLLHUP reporting unchanged and simply add a new bit that is set in the few
places where it makes sense.  The same thing was discussed and conceptually
agreed quite some time ago:

http://lkml.org/lkml/2003/7/12/116

Since this new event bit is added to the existing Linux poll infrastruture,
even the existing poll/select system calls will be able to use it.  As far
as the existing POLLHUP handling, the patch leaves it as is.  The
pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing
archs and sets the bit in the six relevant files.  The other attached diff
is the simple change required to sys/epoll.h to add the EPOLLRDHUP
definition.

There is "a stupid program" to test POLLRDHUP delivery here:

 http://www.xmailserver.org/pollrdhup-test.c

It tests poll(2), but since the delivery is same epoll(2) will work equally.

set_pgdir isn't needed anymore for a very long time.  Remove the leftover
implementation on sh64 and the stub on s390.
