03841f4eec Eliminate potential overflows by allocating softc dynamically,
removing at the same time the need for this to be a "count" config

90af4afacb - Merge struct procsig with struct sigacts.
- Move struct sigacts out of the u-area and malloc() it using the
  M_SUBPROC malloc bucket.
- Add a small sigacts_*() API for managing sigacts structures: sigacts_alloc(),
  sigacts_free(), sigacts_copy(), sigacts_share(), and sigacts_shared().
- Remove the p_sigignore, p_sigacts, and p_sigcatch macros.
- Add a mutex to struct sigacts that protects all the members of the struct.
- Add sigacts locking.
- Remove Giant from nosys(), kill(), killpg(), and kern_sigaction() now
  that sigacts is locked.
- Several in-kernel functions such as psignal(), tdsignal(), trapsignal(),
  and thread_stopped() are now MP safe.

1328e1c4be Add an argument to get_mcontext() which specified whether the
syscall return values should be cleared.  The system calls
getcontext() and swapcontext() want to return 0 on success
but these contexts can be switched to at a later time so
the return values need to be cleared in the saved register
sets.  Other callers of get_mcontext() would normally want
the context without clearing the return values.

Remove the i386-specific context saving from the KSE code.
get_mcontext() is not i386-specific any more.

Fix a bad pointer in the alpha get_mcontext() code.  The
context was being bcopy()'d from &td->tf_frame, but tf_frame
is itself a pointer, so the thread was being copied instead.

of the infrastructure for the gamma driver which was removed a while back.
The DRM_LINUX option is removed because the handler is now provided by the

87b4a25958 Add device driver support for the ASIX Electronics AX88172 USB 2.0
ethernet controller. The driver has been tested with the LinkSys
USB200M adapter. I know for a fact that there are other devices out
there with this chip but don't have all the USB vendor/device IDs.

Note: I'm not sure if this will force the driver to end up in the
install kernel image or not. Special magic needs to be done to exclude
it to keep the boot floppies from bloating again, someone please
advise.

b8db34d280 - Define a new md function 'casuptr'. This atomically compares and sets
a pointer that is in user space.  It will be used as the basic primitive
   for a kernel supported user space lock implementation.
 - Implement this function in x86's support.s
 - Provide stubs that return -1 in all other architectures.  Implementations
   will follow along shortly.

227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

Ruslan Ermilov
824018495d Implemented "nooption" and "nomakeoption" config(8) tokens.
Fixed memory leak in the "nodevice" option implementation.

Use these instead of sed(1) in MD NOTES.

Use a single makefile (sys/conf/makeLINT.mk) to generate
LINT for all architectures.  (Previous versions missed
the LINT dependency on Makefile, and i386 version also
missed the dependency on ${NOTES}.)

Fixed bugs in the previous NOTES conversion using the
"nodevice" token and sed(1):

- i386 LINT lost "device pst".

- pc98 LINT lost SC_*, MAXCONS and KBD_DISABLE_KEYMAP_LOAD
  options, and got needless DPT_* options.

- Added nooptions PPC_DEBUG, PPC_PROBE_CHIPSET, KBD_INSTALL_CDEV
  to sparc64 LINT so that it has a chance to config(8).

This basically returns us to where we were before.

b9deb009c2 Convert one more d_mmap_t consumer I missed in my previous commit. 2003-02-25 13:30:50 +00:00
Maxime Henrion
07159f9c56 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.
