For little-endian, the layout is the same, with\nsignals 1-32 in the first 4 bytes, signals 33-64 in the second, etc.; for\nbig-endian, userspace has that layout while in the kernel each 8 bytes have\nthe two halves swapped from the userspace layout.\n\nThe N32 sigsuspend syscall uses sigset_from_compat to convert the userspace\nsigset to kernel format. If __COMPAT_ENDIAN_SWAP__ is *not* set, this uses\nlogic of the form\n\n set-\u003esig[0] \u003d compat-\u003esig[0] | (((long)compat-\u003esig[1]) \u003c\u003c 32 )\n\nto convert the userspace sigset to a kernel one. This looks correct to me\nfor both big and little endian, given that in userspace compat-\u003esig[1] will\nrepresent signals 33-64, and so will the high 32 bits of set-\u003esig[0] in the\nkernel. If however __COMPAT_ENDIAN_SWAP__ *is* set, as it is for\n__MIPSEL__, it uses\n\n set-\u003esig[0] \u003d compat-\u003esig[1] | (((long)compat-\u003esig[0]) \u003c\u003c 32 );\n\nwhich seems incorrect for both big and little endian, and would\nexplain the observed symptoms.\n\nThis code is the only use of __COMPAT_ENDIAN_SWAP__, so if incorrect\nthen that macro serves no purpose, in which case something like the\nfollowing patch would seem appropriate to remove it.\n\nSigned-off-by: Joseph Myers \u003cjoseph@codesourcery.com\u003e\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9216dfad4fc97ab639ef0885efc713f3d7a20d5b", "tree": "546e301f3181f56133509327f9c5ed035dd4b50d", "parents": [ "1b2db9fb7adc4d67d9ce7d16ce79c41ee84730fe" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Fri Jun 23 02:03:57 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:42:53 2006 -0700" }, "message": "[PATCH] move_pages: fix 32 -\u003e 64 bit compat function\n\nThe definition of the third parameter is a pointer to an array of virtual\naddresses which give us some trouble.
