* [PATCH] atomic: inc_not_zeroNick Piggin2005-11-141-0/+19
| | | | | | | | | | | Introduce an atomic_inc_not_zero operation. Make this a special case of atomic_add_unless because lockless pagecache actually wants atomic_inc_not_negativeone due to its offset refcount.

| * Define MAX_UDELAY_MSAtsushi Nemoto2005-11-071-0/+9
| | | | | | | | | | | | | | | | If HZ was 1000, mdelay(2) cause overflow on multiplication in __udelay. We should define MAX_UDELAY_MS properly to prevent this. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * Use rtc_lock to protect RTC operationsAtsushi Nemoto2005-11-072-2/+25
| | | | | | | | | | | | | | | | | | Many RTC routines were not protected against each other, so there are potential races, for example, ntp-update against /dev/rtc. This patch fixes them using rtc_lock. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * Remove mips_rtc_lockAtsushi Nemoto2005-11-071-7/+0
| | | | | | | | | | | | | | | | | | | | | | The mips_rtc_lock is no longer needed because RTC operations should be protected already by other mechanism. (rtc_lock, local_irq_save, etc.) Also, locking whole rtc_get_time/rtc_set_time should be avoided while some RTC routines might take very long time (a few seconds).

* [PATCH] vm: remove unused/broken page_pte[_prot] macrosTejun Heo2005-10-312-2/+0
| | | | | | | | | | | | | | | | | | | | | | | This patch removes page_pte_prot and page_pte macros from all architectures. Some architectures define both, some only page_pte (broken) and others none. These macros are not used anywhere. page_pte_prot(page, prot) is identical to mk_pte(page, prot) and page_pte(page) is identical to page_pte_prot(page, __pgprot(0)). * The following architectures define both page_pte_prot and page_pte arm, arm26, ia64, sh64, sparc, sparc64 * The following architectures define only page_pte (broken) frv, i386, m32r, mips, sh, x86-64 * All other architectures define neither Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* The type of sum in csum_tcpudp_nofold is "unsigned int", so when we assignRalf Baechle2005-10-291-1/+1
| | | | | | | | | | | | | | | to it in an asm() block, and we're running on a system with 64-bit registers, it is vitally important that we sign extend it correctly before returning to C. Otherwise the stray high bits will be preserved into csum_fold, and on the SB-1 processor, 32-bit arithmetic on a non sign-extended register will yield surprising results. This caused incorrect checksums in some UDP packets for NFS root. The problem was mild when using a 10.0.1.x IP address, but severe when using 192.168.1.x.
