2006-04-19[PATCH] uml: physical memory map file fixesRob Landley
UML really wants shared memory semantics form its physical memory map file, and the place for that is /dev/shm. So move the default, and fix the error messages to recognize that this value can be overridden.

Clean up the jmpbuf code. Since softints, we no longer use sig_setjmp, so the UML_SIGSETJMP wrapper now has a misleading name. Also, I forgot to change the buffers from sigjmp_buf to jmp_buf.

2006-04-19[PATCH] m32r: Fix pt_regs for !COFNIG_ISA_DSP_LEVEL2 targetHirokazu Takata
This modification is required to fix debugging function for m32r targets with !CONFIG_ISA_DSP_LEVEL2, by unifying 'struct pt_regs' and 'struct sigcontext' size for all M32R ISA. Some m32r processor core with !CONFIG_ISA_DSP_LEVEL2 configuration has only single accumulator a0 (ex. VDEC2 core, M32102 core, etc.), the others with CONFIG_ISA_DSP_LEVEL2 has two accumulators, a0 and a1. This means there are two variations of thread context. So far, we reduced and changed stackframe size at a syscall for their context size. However, this causes a problem that a GDB for processors with CONFIG_ISA_DSP_LEVEL2 cannot be used for processors with !CONFIG_ISA_DSP_LEVEL2. From the viewpoint of GDB support, we should reduce such variation of stackframe size for simplicity. In this patch, dummy members are added to 'struct pt_regs' and 'struct sigcontext' to adjust their size for !CONFIG_ISA_DSP_LEVEL2. This modification is also a one step for a GDB update in future. Currently, on the m32r, GDB can access process's context by using ptrace functions in a simple way of register by register access. By unifying stackframe size, we have a possibility to make use of ptrace functions of not only a single register access but also block register access, PTRACE_{GETREGS,PUTREGS}. However, for this purpose, we might have to modify stackframe structure some more; for example, PSW (processor status word) register should be pre-processed before pushing to stack at a syscall, and so on. In this case, we must update carefully both kernel and GDB at a time...

2006-04-19[PATCH] uml: MADV_REMOVE fixesJeff Dike
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.

2006-04-19[PATCH] uml: make 64-bit COW files compatible with 32-bit onesPaolo 'Blaisorblade' Giarrusso
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.

2006-04-19[MIPS] Rewrite all the assembler interrupt handlers to C.Ralf Baechle
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: Ralf Baechle <ralf@linux-mips.org>
