Revision 05d43ed8a89c159ff641d472f970e3f1baa66318 authored by H. Peter Anvin on 29 January 2010, 06:14:43 UTC, committed by Linus Torvalds on 29 January 2010, 16:22:01 UTC 
x86: get rid of the insane TIF_ABI_PENDING bit
 
Now that the previous commit made it possible to do the personality
setting at the point of no return, we do just that for ELF binaries.
And suddenly all the reasons for that insane TIF_ABI_PENDING bit go
away, and we can just make SET_PERSONALITY() just do the obvious thing
for a 32-bit compat process.

Everything becomes much more straightforward this way.

	help
	  If you say Y here, it will be possible to remotely debug the
	  kernel using gdb.  It is recommended but not required, that
	  you also turn on the kernel config option
	  CONFIG_FRAME_POINTER to aid in producing more reliable stack
	  backtraces in the external debugger.  Documentation of
	  kernel debugger is available at http://kgdb.sourceforge.net
	  as well as in DocBook form in Documentation/DocBook/.  If
	  unsure, say N.

	  Share a serial console with kgdb. Sysrq-g must be used

	help
	  This is a kgdb I/O module specifically designed to test
	  kgdb's internal functions.  This kgdb I/O module is
	  intended to for the development of new kgdb stubs
	  as well as regression testing the kgdb internals.
	  See the drivers/misc/kgdbts.c for the details about
	  the tests.  The most basic of this I/O module is to boot
	  a kernel boot arguments "kgdbwait kgdbts=V1F100"

config KGDB_TESTS_ON_BOOT
	bool "KGDB: Run tests on boot"
	depends on KGDB_TESTS
	default n
	help
	  Run the kgdb tests on boot up automatically without the need
	  to pass in a kernel parameter

config KGDB_TESTS_BOOT_STRING
	string "KGDB: which internal kgdb tests to run"
	depends on KGDB_TESTS_ON_BOOT
	default "V1F100"
	help
	  This is the command string to send the kgdb test suite on
	  boot.  See the drivers/misc/kgdbts.c for detailed
	  information about other strings you could use beyond the
	  default of V1F100.
