* mem: add missed MAP_HUGETLB mmap flagKirill A. Shutemov2014-01-05

* tile: remove MAP_CACHE_xxx support in mem.cChris Metcalf2013-05-23
| | | | | | | | | | | | | These flags support functionality in mmap() that has not been pushed back to the community, and which may or may not eventually end up being the final community model. In the interim, having these flags unconditionally present for "#ifdef TILE" just means that the TILE build breaks if using the community versions of the kernel and glibc, so just revert the code until such time as it may end up in the community.

* Clean up mmap decodingDenys Vlasenko2013-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous code merges too many similar, but different ways of decoding mmap. For example, sys_old_mmap is "params in memory" API... except SH[64], where it is "params in regs", i.e. what sys_mmap ("new mmap") function does on other arches! It's much simpler when every mmap handler has same API regardless of arch. Where API means whether params are in regs or in memory, and whether offset is in bytes, pages, or 4k blocks. Then we just insert correct function pointers into arch syscall tables. It turns out there are four common mmap APIs over all architectures which exist in Linux kernel, and one outlier for S390. A number of mmap decoders were plain wrong in arch tables. For example, BFIN has no old_mmap. It returns ENOSYS. I checked kernel sources for all arches nad fixed the tables. There was dead code for x86_64 for old_mmap: x86_64 has no old_mmap. * mem.c: Refactor mmap functions so that we have five mmap syscall handlers, each with the fixed API (not varying by arch). * pathtrace.c (pathtrace_match): Adjust sys_func == mmap_func checks. * linux/syscall.h: Declare new mmap syscall handler functions. * linux/arm/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/avr32/syscallent.h: mmap is sys_mmap_pgoff. * linux/bfin/syscallent.h: old_mmap is ENOSYS, mmap2 is sys_mmap_pgoff. * linux/hppa/syscallent.h: mmap2 is sys_mmap_4koff. * linux/i386/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/ia64/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/m68k/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/microblaze/syscallent.h: old_mmap is sys_mmap, mmap2 is sys_mmap_pgoff. * linux/mips/syscallent.h: mmap is sys_mmap_4kgoff. * linux/or1k/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/powerpc/syscallent.h: mmap2 is sys_mmap_4kgoff. * linux/s390/syscallent.h: mmap2 is sys_old_mmap_pgoff. * linux/s390x/syscallent.h: mmap is sys_old_mmap and thus has 1 arg. * linux/sh/syscallent.h: old_mmap2 is sys_mmap, mmap2 is sys_mmap_4koff. * linux/sh64/syscallent.h: Likewise. * linux/sparc/syscallent1.h: mmap is TD|TM. * linux/tile/syscallent1.h: mmap2 is sys_mmap_4koff.

* Remove code which supports systems with long long off_t.Denys Vlasenko2013-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While looking at mmap mess, did experimenting in order to figure out what gets used when. Tried building armv4tl, armv5l, armv6l, mips, mipsel, i686, x86_64 and none of they have long long off_t, which isn't suprprising: we aren't using glibc defines which enable that. Moreover, we SHOULD NOT use off_t in syscall decode! Its size depends on libc, not on arch! I.e. it is essentially unpredictable and can even in theory vary on the same arch with different libc. We should use longs or long longs, in a way which matches architectural ABI for the given syscall. There are usually *at most* two permutations, no need to add yet another variable (sizeof(off_t)) to the mix. This change removes almost all HAVE_LONG_LONG_OFF_T conditionals, which will reveal further possible simplifications. * mem.c: Remove code conditional on HAVE_LONG_LONG_OFF_T. As a result, never remap sys_mmap64 to sys_mmap. (print_mmap): Compile unconditionally. (sys_old_mmap): Compile unconditionally. (sys_mmap): Compile unconditionally. * io.c (sys_sendfile): Add a FIXME comment. * file.c: Remove code conditional on HAVE_LONG_LONG_OFF_T.
