14 If you say Y here then read-write lock processing will count how many
15 times it has tried to get the lock and issue an error message after
16 too many attempts. If you suspect a rwlock problem or a kernel
17 hacker asks for this option then say Y. Otherwise say N.
19 config DEBUG_SEMAPHORE
20 bool "Semaphore debugging"
21 depends on DEBUG_KERNEL
23 If you say Y here then semaphore processing will issue lots of
24 verbose debugging messages. If you suspect a semaphore problem or a
25 kernel hacker asks for this option then say Y. Otherwise say N.

28 bool "Legacy kernel start address"
29 depends on ALPHA_GENERIC
32 The 2.4 kernel changed the kernel start address from 0x310000
33 to 0x810000 to make room for the Wildfire's larger SRM console.
34 Recent consoles on Titan and Marvel machines also require the
37 If you're using aboot 0.7 or later, the bootloader will examine the
38 ELF headers to determine where to transfer control. Unfortunately,
39 most older bootloaders -- APB or MILO -- hardcoded the kernel start
40 address rather than examining the ELF headers, and the result is a
43 Say Y if you have a broken bootloader. Say N if you do not, or if
44 you wish to run on Wildfire, Titan, or Marvel.

55 This option is required for IEEE compliant floating point arithmetic
56 on the Alpha. The only time you would ever not say Y is to say M in
57 order to debug the code. Say Y unless you know what you are doing.
