3383 5751 d 13 h svoboda /trunk/kernel/generic/src/mm/ Fix panic caused by not setting new area flags in as_area_change_flags(), as pointed out by Jakub.  
3382 5752 d 1 h jermar /trunk/kernel/generic/src/mm/ Fix the rare case when the anon or ELF backend uses PFN 0 for mapping.  
3240 5784 d 12 h decky / move unfinished ObjC support to a separate branch  
3222 5807 d 7 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5809 d 3 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.		  
3207 5809 d 3 h jermar /trunk/kernel/generic/ Introduce FRAME_LOW_16_GiB slab/frame allocator flag. When specified, the
allocators will not allocate memory above 16 GiB. Each architecture needs to
make sure not to merge zones from below and above 16 GiB. Allocations that
require memory below 16 GiB need to be altered to use this flag.		  
3206 5809 d 5 h jermar /trunk/kernel/generic/ Avoid deadlock during the 'zone n' kconsole command. Buddy allocator detail is
no longer printed because the effort to avoid the deadlock was simply not worth
it.		  
3205 5809 d 7 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3188 5822 d 0 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5822 d 4 h jermar /trunk/kernel/generic/src/mm/ Get rid of the infamous "Sleep not implemented" panic during low memory
condition. Use a condition variable to implement the sleep. As of now, the
condition is rather coarse and can cause that threads may sleep unnecessarily.
Needs to be fine tuned and based on the amount of memory available.		  
3186 5822 d 4 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.		  
3185 5823 d 4 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3183 5823 d 8 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3180 5824 d 14 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3143 5831 d 6 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5831 d 7 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5831 d 10 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3130 5833 d 15 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5834 d 4 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3104 5839 d 15 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.
