MADV_REMOVE fixes - change the test mapping to be MAP_SHARED instead of MAP_PRIVATE, as MADV_REMOVE on MAP_PRIVATE maps won't work. Also, use the kernel's definition of MADV_REMOVE instead of hardcoding it if there isn't a libc definition. Signed-off-by:

for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu. Signed-off-by:

While we can currently walk through thread groups, process groups, and sessions with just the rcu_read_lock, this opens the door to walking the entire task list. We already have all of the other RCU guarantees so there is no cost in doing this, this should be enough so that proc can stop taking the tasklist lock during readdir. prev_task was killed because it has no users, and using it will miss new tasks when doing an rcu traversal.

This is the minimal fix to make 64-bit UML binaries create 32-bit compatible COW files and read them. I've indeed tested that current code doesn't do this - the code gets SIGFPE for a division by a value read at the wrong place, where 0 is found. Signed-off-by:

This fixes kernel builds with gcc 3.2 (not 64-bit, that is looking like it is beyond recovery) and 3.3. With these bugs fixed we now also can get undo 3b4c4996a0c24da9e6f8be764e3950b756b18cc0 and similar bits for SMTC that were added in 79cc8007b93838a670b164b8a55ab3e735a12a8b. Signed-off-by: -

Saves like 1,600 lines of code, is way easier to debug, compilers frequently do a better job than the cut and paste type of handlers many boards had. And finally having all the stuff done in a single place also means alot of bug potencial for the MT ASE is gone. The only surviving handler in assembler is the DECstation one; I hope Maciej will rewrite it. Signed-off-by: -
