uml: LDT mutex conversion

2008-02-05T17:44:31+00:00

The ldt.semaphore conforms to the new struct mutex requirments, so I converted
it to use the new API and changed the name.

uml: fold mmu_context_skas into mm_context

2007-10-16T16:43:06+00:00

This patch folds mmu_context_skas into struct mm_context, changing all users
of these structures as needed.

[PATCH] uml: split ldt.h in arch-independent and arch-dependant code

2006-03-31T20:18:51+00:00

ldt-{i386,x86_64}.h is made of two different parts - some code for parsing of
LDT descriptors, which is arch-dependant, and the code to handle uml_ldt_t (an
LDT block inside UML), which is mostly arch-independant (among x86 and x86_64,
at least).

Join the common part in a single file (ldt.h) and split the rest away
(host_ldt-{i386,x86_64}.h).

This is needed because processor.h, with next patches, will start including
the LDT descriptor parsing macros in host_ldt.h, but it can't include ldt.h
because it uses semaphores (and to define semaphores one must first include
processor.h!).

[PATCH] uml: eliminate anonymous union and clean up symlink lossage

2005-11-22T17:13:41+00:00

This gives a name to the anonymous union introduced in skas-hold-own-ldt,
allowing to build on a wider range of gccs.

It also removes ldt.h, which somehow became real, and replaces it with a
symlink, and creates ldt-x86_64.h as a copy of ldt-i386.h for now.

[PATCH] uml: maintain own LDT entries

2005-11-07T15:53:31+00:00

Patch imlements full LDT handling in SKAS:
 * UML holds it's own LDT table, used to deliver data on
   modify_ldt(READ)
 * UML disables the default_ldt, inherited from the host (SKAS3)
   or resets LDT entries, set by host's clib and inherited in
   SKAS0
 * A new global variable skas_needs_stub is inserted, that
   can be used to decide, whether stub-pages must be supported
   or not.
 * Uses the syscall-stub to replace missing PTRACE_LDT (therefore,
   write_ldt_entry needs to be modified)

[PATCH] uml: consolidate modify_ldt

2005-07-14T16:00:24+00:00

*) Reorganize the two cases of sys_modify_ldt to share all the reasonably
   common code.

*) Avoid memory allocation when unneeded (i.e.  when we are writing and the
   passed buffer size is known), thus not returning ENOMEM (which isn't
   allowed for this syscall, even if there is no strict "specification").

*) Add copy_{from,to}_user to modify_ldt for TT mode.
