| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Minor cleanups to the OMAP RNG: - Comment update re RNG status: * yes, it works on 16xx; "rngtest" is quite happy * it's fast enough that polling vs IRQ is a non-issue - Get rid of BUG_ON - Help GCC not be stupid about inlining (object code shrink) - Remove "sparse" warning - Cope with new hotplug rule requiring "platform:" modalias And make the file header match kernel conventions.

| * [CRYPTO] tcrypt: Change the XTEA test vectorsSebastian Siewior2008-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The third test vector of ECB-XTEA-ENC fails for me all other are fine. I could not find a RFC or something else where they are defined. The test vector has not been modified since git started recording histrory. The implementation is very close (not to say equal) to what is available as Public Domain (they recommend 64 rounds and the in kernel uses 32). Therefore I belive that there is typo somewhere and tcrypt reported always *fail* instead of *okey*. This patch replaces input + result of the third test vector with result + input from the third decryption vector. The key is the same, the other three test vectors are also the reverse.

| * [CRYPTO] tcrypt: Shrink the tcrypt moduleSebastian Siewior2008-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the tcrypt module is about 2 MiB on x86-32. The main reason for the huge size is the data segment which contains all the test vectors for each algorithm. The test vectors are staticly allocated in an array and the size of the array has been drastically increased by the merge of the Salsa20 test vectors. With a hint from Benedigt Spranger I found a way how I could convert those fixed-length arrays to strings which are flexible in size. VIM and regex were also very helpfull :) So, I am talking about a shrinking of ~97% on x86-32: text data bss dec hex filename 18309 2039708 20 2058037 1f6735 tcrypt-b4.ko 45628 23516 80 69224 10e68 tcrypt.ko Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | ptrace: compat_ptrace_request siginfoRoland McGrath2008-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for PTRACE_GETSIGINFO and PTRACE_SETSIGINFO in compat_ptrace_request. It relies on existing arch definitions for copy_siginfo_to_user32 and copy_siginfo_from_user32. On powerpc, this fixes a longstanding regression of 32-bit ptrace calls on 64-bit kernels vs native calls (64-bit calls or 32-bit kernels). This can be seen in a 32-bit call using PTRACE_GETSIGINFO to examine e.g. siginfo_t.si_addr from a signal that sets it. (This was broken as of 2.6.24 and, I presume, many or all prior versions.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lockdep found out that we can occasionally take the device-tree lock for reading from softirq time (from rtas_token called by the rtas real time clock code called by the NTP code), while we take it occasionally for writing without masking interrupts. The combination of those two can thus deadlock. While some of those cases of interrupt read lock could be fixed (such as caching the RTAS tokens) I figured that taking the lock for writing is so rare (device-tree modification) that we may as well penalize that case and allow reading from interrupts. Thus, this turns all the writers to take the lock with irqs masked to avoid the situation.

| * | [POWERPC] Turn xics_setup_8259_cascade() into a generic ↵Michael Ellerman2008-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pseries_setup_i8259_cascade() Remove the xics references from xics_setup_8259_cascade(), and merge the good bits from the almost identical logic in pseries_mpic_init_IRQ().

| * | [POWERPC] Move xics_setup_8259_cascade() into platforms/pseries/setup.cMichael Ellerman2008-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in xics.c to setup the i8259 cascaded irq handler is not really xics specific, so move it into setup.c - we will clean this up further in a subsequent patch.

| * | [POWERPC] Use asm-generic/bitops/find.h in bitops.hAlexander van Heukelum2008-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Powerpc and ppc have some code in their bitops.h that is exactly the same as asm-generic/bitops/find.h. Include this header instead of the private implementation. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Paul Mackerras <paulus@samba.org>
