Blackfin: portmux: fix peripheral map overflow when requesting pins

Some processors have groups of pins that aren't an even number of 16.
This causes the array size calculation to under count the number of
needed entries due to integer truncation.  So on the BF51x, while we
should have 3 bitmaps (41 / 16), we end up with 2 and pin requests for
the 3rd bank end up scribbling over the top of the GPIO IRQ array.

docbook: use IDs as filenames to support multiple books

I'm trying to generate a <set> of <book>s in docbook for wireless to
link together all the cfg80211 and mac80211 documentation.

However, docbook will generate "re01.html" anew for each book for the
first <refentry>, presumably due to a bug in the stylesheets.

An effective workaround is to use IDs for the filenames, which makes
them more descriptive as well, e.g.  API-enum-ieee80211-band.html.

Jason Wessel [Thu, 5 Aug 2010 14:22:22 +0000]
gdbstub: do not directly use dbg_reg_def[] in gdb_cmd_reg_set()

Presently the usable registers definitions on x86 are not contiguous
for kgdb.  The x86 kgdb uses a case statement for the sparse register
accesses.  The array which defines the registers (dbg_reg_def) should
not be used directly in order to safely work with sparse register
definitions.

Specifically there was a problem when gdb accesses ORIG_AX, which is
accessed only through the case statement.

This patch encodes register memory using the size information provided
from the debugger which avoids the need to look up the size of the
register.  The dbg_set_reg() function always further validates the
inputs from the debugger.

9 years agogdbstub: Optimize kgdb's "thread:" response for the gdb serial protocol
Jason Wessel [Thu, 5 Aug 2010 14:22:19 +0000]
gdbstub: Optimize kgdb's "thread:" response for the gdb serial protocol

The gdb debugger understands how to parse short versions of the thread
reference string as long as the bytes are paired in sets of two
characters.  The kgdb implementation was always sending 8 leading
zeros which could be omitted, and further optimized in the case of
non-negative thread numbers.  The negative numbers are used to
reference a specific cpu in the case of kgdb.

An example of the previous i386 stop packet looks like:
    T05thread:00000000000003bb;

New stop packet response:
    T05thread:03bb;

The previous ThreadInfo response looks like:
    m00000000fffffffe,0000000000000001,0000000000000002,0000000000000003,0000000000000004,0000000000000005,0000000000000006,0000000000000007,000000000000000c,0000000000000088,000000000000008a,000000000000008b,000000000000008c,000000000000008d,000000000000008e,00000000000000d4,00000000000000d5,00000000000000dd

    mfffffffe,01,02,03,04,05,06,07,0c,88,8a,8b,8c,8d,8e,d4,d5,dd
