Heinrich Schuchardt 11353d7b62 getrandom.2: Clarification of open questions 
With his last patches for getrandom.2 Michael Kerrisk posed a few
questions and left some comments in the man-page. This patch
seeks to clarify the open issues.

 72 For example, if the call is interrupted by a signal handler,
 73 it may return a partially filled buffer, or fail with the error
 74 .BR EINTR .
 75 .\" Tested with buffer sizes > 256 bytes: both partial reads
 76 .\" and EINTR can occur, with the former being more frequent.
 77 .\"

Michael's observation agrees with the code.
For buffer size > 256: If the buffer is still empty EINTR occurs.
If any number of bytes has been read to the buffer, that number
is returned.  The comment can be removed.

 78 .\" mtk: In the absence of signals, in my testing, even very large reads
 79 .\" return full buffers. I found that reads of up to 33554431 always
 80 .\" returned a filled buffer. Specifying 'buflen' > 33554431 always
 81 .\" returned just 33554431 bytes. (I'm not sure where that number comes
        from.

The maximum number of bytes transferred is limited for
/dev/urandom to:

    nbytes = min_t(size_t, nbytes, INT_MAX >> (ENTROPY_SHIFT + 3));
    // <= 0x1fffff

and for /dev/random to
nbytes = min_t(size_t, nbytes, SEC_XFER_SIZE); // <= 0x200

Lets put this into the NOTES section.

 224 When reading from
 225 .IR /dev/random ,
 226 blocking requests of any size can be interrupted by a signal
 227 (the call fails with the error
 228 .BR EINTR ).

Thats ok.

 82 If the pool has not yet been initialized, then the call blocks, unless
 83 .B GRND_RANDOM
 84 is specified in
 85 .IR flags .
 86 .\" FIXME We need a bit more information here.
 87 .\"       The reader will ask: when is /dev/urandom initialized?
 88 .\"       There should be some text here to explain that.

Entropy is collected from different sources, e.g.
 - time of reaping a thread
 - MAC address of a network interfaces
 - Allwinner security ID
 - ROM content of a firewire device
 - ...

When more than 128 bits have been collected, the pool is set
to initialized.

I suggest that detailed information about the initialization
should be provided on the random.4 page.

I added a paragraph in the NOTES section.

Vince Weaver 747a6e7ce0 perf_event_open.2: srcfix: add git commit references 
I noticed you were adding git commit references to the various
Linux version markers.

This adds git commit references for all Linux kernel version
notes in perf_event_open.2

mtk: I backed out two pieces of Vince's patch that were not
source comments. They can be dealt with as separate commits.
