[POWERPC] Better check in show_instructions

2006-10-16T05:53:30+00:00

Instead of just checking that an address is in the right range, use the
provided __kernel_text_address() helper which covers both the kernel and
module text sections.

[PATCH] namespaces: utsname: use init_utsname when appropriate

2006-10-02T14:57:21+00:00

In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use.  This patch replaces those with a the init_utsname
helper.

Changes: Removed several uses of init_utsname().  Hope I picked all the
	right ones in net/ipv4/ipconfig.c.  These are now changed to
	utsname() (the per-process namespace utsname) in the previous
	patch (2/7)

[PATCH] powerpc: Implement PR_[GS]ET_UNALIGN prctls for powerpc

2006-06-09T11:24:16+00:00

This gives the ability to control whether alignment exceptions get
fixed up or reported to the process as a SIGBUS, using the existing
PR_SET_UNALIGN and PR_GET_UNALIGN prctls.  We do not implement the
option of logging a message on alignment exceptions.

[PATCH] powerpc: Implement support for setting little-endian mode via prctl

2006-06-09T11:24:15+00:00

This adds the PowerPC part of the code to allow processes to change
their endian mode via prctl.

This also extends the alignment exception handler to be able to fix up
alignment exceptions that occur in little-endian mode, both for
"PowerPC" little-endian and true little-endian.

We always enter signal handlers in big-endian mode -- the support for
little-endian mode does not amount to the creation of a little-endian
user/kernel ABI.  If the signal handler returns, the endian mode is
restored to what it was when the signal was delivered.

We have two new kernel CPU feature bits, one for PPC little-endian and
one for true little-endian.  Most of the classic 32-bit processors
support PPC little-endian, and this is reflected in the CPU feature
table.  There are two corresponding feature bits reported to userland
in the AT_HWCAP aux vector entry.

This is based on an earlier patch by Anton Blanchard.

[PATCH] unexport get_wchan

2006-03-31T20:19:01+00:00

The only user of get_wchan is the proc fs - and proc can't be built modular.

[PATCH] powerpc: export validate_sp for oprofile calltrace

Export validate_sp so we can use it in the oprofile calltrace code.

[PATCH] powerpc: declare arch syscalls in

2006-03-27T03:48:22+00:00

powerpc currently declares some of its own system calls
in , but not all of them. That place also
contains remainders of the now almost unused kernel syscall
hack.

 - Add a new  with clean declarations
 - Include that file from every source that implements one
   of these
 - Get rid of old declarations in 

This patch is required as a base for implementing system
calls from an SPU, but also makes sense as a general
cleanup.

[PATCH] kretprobe instance recycled by parent process

2006-03-26T16:57:04+00:00

When kretprobe probes the schedule() function, if the probed process exits
then schedule() will never return, so some kretprobe instances will never
be recycled.

In this patch the parent process will recycle retprobe instances of the
probed function and there will be no memory leak of kretprobe instances.
