[PARISC] fix personality flag check in copy_thread()

2012-08-03T10:25:12+00:00

Directly comparing task_struct->personality against PER_* is not fully
correct, as it doesn't take flags potentially stored in top three bytes
into account.

Analogically, directly forcefully setting personality to PER_LINUX32 or
PER_LINUX discards any flags stored in the top three bytes.

improve sys_newuname() for compat architectures

2010-03-12T23:52:32+00:00

On an architecture that supports 32-bit compat we need to override the
reported machine in uname with the 32-bit value.  Instead of doing this
separately in every architecture introduce a COMPAT_UTS_MACHINE define in
 and apply it directly in sys_newuname().

unified (weak) sys_pipe implementation

2008-05-03T20:50:33+00:00

This replaces the duplicated arch-specific versions of "sys_pipe()" with
one unified implementation.  This removes almost 250 lines of duplicated
code.

It's marked __weak, so that *if* an architecture wants to override the
default implementation it can do so by simply having its own replacement
version, since many architectures use alternate calling conventions for
the 'pipe()' system call for legacy reasons (ie traditional UNIX
implementations often return the two file descriptors in registers)

I still haven't changed the cris version even though Linus says the BKL
isn't needed.  The arch maintainer can easily do it if there are really
no obstacles.

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

get_unmapped_area handles MAP_FIXED on parisc

2007-05-07T19:12:56+00:00

Handle MAP_FIXED in parisc arch_get_unmapped_area(), just return the address.
We might want to also check for possible cache aliasing issues now that we get
called in that case (like ARM or MIPS), leave a comment for the maintainers to
pick up.

[PA-RISC] Fix parisc_newuname()

2006-10-05T01:48:18+00:00

The utsname virtualisation broke parisc_newuname compilation.
Rewrite the implementation to call sys_newuname() like sparc64 does.

[PARISC] Add new entries to the syscall table
