You have misread the statement; here is the interpretation, according to strict English rules: (some subtle problems in the code in locore.s, machdep.c, and pmap.c in the mp case, when interacting with the PG_G bit) || (some subtle problems in the code in locore.s, machdep.c, and pmap.c in the mp case, when interacting with the PG_PSE bit). To make this clear: this is why the final word "bits" was plural, ending with "PG_G and PG_PSE bits" rather than "PG_G bit and PG_PSE bit". The use of the conjunctive "and" was the same as in "cancer is caused in humans by exposure to benzine and amyl nitrate". Hope this clarifies my statement for you... -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
