Shiqing Gao d97224a4b5 hv: fix integer violations
fix the following integer violations:
1. Signed/unsigned conversion without cast
2. Literal value requires a U suffix
3. Implicit conversion of underlying type

v3 -> v4:
 * change the type of npk_loglevel/mem_loglevel/console_loglevel
   from uint32_t to uint16_t

v2 -> v3:
 * discard the return value of update_ept
 * discard changes related to npk loglevel

v1 -> v2:
 * remove the unnecessary changes related to the false positive
   issues caused by scanning tool
 * change the type of the local variable 'vlapic_id' from uint8_t
   to uint32_t in function 'vlapic_build_id'
 * change the type of the struct member 'flags' in shared_buf from
   uint64_t to uint32_t

Mingqiang Chi 2975f9fa65 hv:Replace dynamic memory with static for sbuf
--Config LOG_BUF_SIZE 256KB for per cpu
--Replace 'calloc' with static array for sbuf
--Rename 'alloc_earlylog_sbuf' to 'init_earlylog_sbuf'
--Remove deadcode sbuf_free

v2-->v3:
 -- put the buffer into per_cpu data structure
v1-->v2:
 -- add 'is_early_logbuf' in percpu data structure used for
    check if need to do 'do_copy_earlylog'

Chinthapally, Manisha cab93c053a HV:Added SBuf support to copy samples generated to guest.
sbuf.h:
    Added new shared buffer types for SEP and SOCWATCH

profiling.c
   sbuf_next_ptr - returns  address of next available buffer

profiling_sbuf_put_variable:
   This function allows to write data of variable size into shared buffer.

profiling_generate_data:
     Read profiling data and transfer to SOS
     Drops transfer of profiling data if sbuf is full/insufficient and log it

Huihuang Shi 2b53acb5f8 HV:change the return type of sbuf_get and sbuf_put
Because of the return type inconsistent,change the
sbuf return type to uint32_t to fix it,and make the
pre-condition to check the parameter whether is NULL.

V1->V2:
  1.add () to bool expression
  2.add pre-assumption to sbuf_get and sbuf_put

Junjun Shan 4fd5102edc hv:treewide:fix multiple MISRAC violations
MISRAC has requirements about literal value requires a U suffix and
signed/unsigned conversion with cast. This patch is used to solve
these violations.

v1->v2
 *Drop the cast of sz from uint32_t to int32_t, the signed/unsigned
  violation of nchars will be solved by other patch together with
  printf/sprintf/console/vuart/uart code.

 *Delete the unnecessary L suffix of shifting operand.

Huihuang Shi 91fdffb19a HV:debug:fix "signed/unsigned conversion without cast"
Misra C required signed/unsigned conversion with cast.

V1->V2:
  a.split patch to patch series

V2->V3:
  a.Change the API tgt_uart/ static int uart16550_get_rx_err(uint32_t rx_data) to return uint32_t
  b.modified the format of if from "if (length > 32*(length/32))" to
"if (length % 32U > 0)"

V3->V4:
  a.change the uint64_t type numeric constant's suffix from U to UL

Xiangyang Wu 3027bfab10 HV: treewide: enforce unsignedness of pcpu_id
In the hypervisor, physical cpu id is defined as "int" or "uint32_t"
type in the hypervisor. So there are some sign conversion issues
about  physical cpu id (pcpu_id) reported by static analysis tool.
Sign conversion violates the rules of MISRA C:2012.

In this patch, define physical cpu id as "uint16_t" type for all
modules in the hypervisor and change related codes. The valid
range of pcpu_id is 0~65534, INVALID_PCPU_ID is defined to the
invalid pcpu_id for error detection, BROADCAST_PCPU_ID is
broadcast pcpu_id used to notify all valid pcpu.

The type of pcpu_id in the struct vcpu and vcpu_id is "int" type,
this will be fixed in another patch.

V1-->V2:
    *  Change the type of pcpu_id from uint32_t to uint16_t;
    *  Define INVALID_PCPU_ID for error detection;
    *  Define BROADCAST_PCPU_ID to notify all valid pcpu.

V2-->V3:
    *  Update comments for INVALID_PCPU_ID and BROADCAST_PCPU_ID;
    *  Update addtional pcpu_id;
    *  Convert hexadecimals to unsigned to meet the type of pcpu_id;
    *  Clean up for MIN_PCPU_ID and MAX_PCPU_ID, they will be
       defined by configuration.
Note: fix bug in the init_lapic(), the pcpu_id shall be less than 8,
this is constraint by implement in the init_lapic().

Huihuang Shi e591315a65 HV:treewide:C99-friendly per_cpu implementation change the per_cpu method
The current implementation of per_cpu relies on several non-c99 features,
and in additional involves arbitrary pointer arithmetic which is not MIS-
RA C friendly.

This patch introduces struct per_cpu_region which holds all the per_cpu
variables. Allocation of per_cpu data regions and access to per_cpu vari-
ables are greatly simplified, at the cost of making all per_cpu varaibl-
es accessible in files.
