 2010/??/??	*** Release of OpenSSI 2.0.0rc1 ***
 
+2010/04/18	rogertsang <[email protected]>
+	* CVS Tags: OPENSSI-FC-1-9-6-PRE38
+
+	* MOSIX (#ifdef SSI_BALANCE_MEMORY):
+	- Use cond_resched_lock() instead of run_over_maxchunk,
+	  sort_age_maxchunk. Prevent needless re-traversing of the page table.
+	- run_over_dirty_pages(), sort_and_age_pages() support 4-level page
+	  table.
+
+	* VPROC:
+	- as_do_pg() use pud_alloc() like install_arg_page() in Linux base;
+	  based on John Hughes' findings.
+	- Fix inappropriate inlining of as_pull_pgdir(), as_count_pgdir().
+	- No need to hold page_table_lock while traversing struct mm->mmap list
+	  of VMA's in as_count_mm_info().
+	- Fix array bounds violation due to as_saved_auxv array in as_info
+	  struct is smaller than saved_auxv array in mm struct.
+	- Use cond_resched_lock() instead of run_over_maxchunk. Prevent
+	  needless re-traversing of the page table.
+	- Fix memory corruption due to do_swap_page() unmapping unmapped PTE in
+	  as_pull_pgdir() path. Memory corruption occurs when the PTE passed to
+	  do_swap_page() is not the first PTE in the list of PTE's because in
+	  as_pull_pgdir() only the first PTE is mapped. Bug only affects
+	  kernels with CONFIG_HIGHPTE defined.
+	- Process migration to support 4-level page table.

+	* CVS Tags: OPENSSI-FC-1-9-6-PRE37
+
+	* IPC Semaphores:
+	- Avoid duplicate pid alive checks when there are multiple
+	  semundo_nodedown_thread()'s. Last thread to reset
+	  sem_semundo->pid_checked. This will prevent the process_is_alive()
+	  storm but depending on timing may leave behind some sem_semundo
+	  structs until the next node down event or until the shared semaphore
+	  is removed.
+	- Fix semundo_nodedown_thread() skipped remaining sem_semundo structs
+	  in sem_array after encountering sem_semundo with pid_checked and pid
+	  was not dead. Bug introduced in OPENSSI-FC-1-9-6-PRE30.
+	- Remove redundant code in semundo_nodedown_thread(). Call
+	  __ssi_semexit() instead.
+	- Move beginning of __ssi_semexit() into ssi_semexit() so that
+	  semundo_nodedown_thread() can use __ssi_semexit().
