It is half that on\n64-bit because the pointers are twice the size.

For each atomic operation, the address\nof the atomic64_t variable is hashed to an index into an array of 16\nspinlocks. That spinlock is taken (with interrupts disabled) around the\noperation, which can then be coded non-atomically within the lock.\n\nOn UP, all the spinlock manipulation goes away and we simply disable\ninterrupts around each operation. In fact gcc eliminates the whole\natomic64_lock variable as well.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "cd166bd0dde265a97dd9aa8e3451a2646d96d04b", "tree": "3a7fb5b8bb8d7676e804845b75977be380b8dcff", "parents": [ "6b702462cbe5b6f372966a53f4465d745d86b65c", "5b02ee3d219f9e01b6e9146e25613822cfc2e5ce" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 12 18:15:51 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 12 18:15:51 2009 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:\n add generic lib/checksum.c\n asm-generic: add a generic uaccess.h\n asm-generic: add generic NOMMU versions of some headers\n asm-generic: add generic atomic.h and io.h\n asm-generic: add legacy I/O header files\n asm-generic: add generic versions of common headers\n asm-generic: make bitops.h usable\n asm-generic: make pci.h usable directly\n asm-generic: make get_rtc_time overridable\n asm-generic: rename page.h and uaccess.h\n asm-generic: rename atomic.h to atomic-long.h\n asm-generic: add a generic unistd.h\n asm-generic: add generic ABI headers\n asm-generic: add generic sysv ipc headers\n asm-generic: introduce asm/bitsperlong.h\n asm-generic: rename termios.h, signal.h and mman.h\n" }, { "commit": "ad6561dffa17f17bb68d7207d422c26c381c4313", "tree": "04cf6480ccd6732ab0ffe3d552bd32599390ff65", "parents": [ "c398df30d5caad626ac72bfab0361a7b0f67a661" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Fri Jun 12 21:47:03 2009 -0600" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Fri Jun 12 21:47:04 2009 +0930" }, "message": "module: trim exception table on init free.\n\nIt\u0027s theoretically possible that there are exception table entries\nwhich point into the (freed) init text of modules.
